Da Cocktails in Top-Bars immer anspruchsvoller werden, ist mehr Arbeit erforderlich, um sie zu perfektionieren, und vieles davon geschieht jetzt hinter den Kulissen.Anstatt Obst in einen großen matel cup & mug zu gießen, der auf der Theke sitzt, verbringen Barkeeper Zeit in einer Küche oder einem Labor mit Vakuummaschinen, Tischstillständen, Industriefiltern und anderen Geräten.Eis ist nicht mehr schnellschmelzende Stücke, die aus einer Maschine ausgespuckt werden;es wird mittels Spezialgetriebe oder handgeschnitzt aus kristallklaren Blöcken durch professionelle Eisschneider in bestimmte Formen eingefroren.Ein leckeres Daiquiri kann Zutaten enthalten, die mit flüssigem Stickstoff eingefroren wurden, destilliert und geklärt wurden, alles, um Ihnen davor zu ersparen, MinzsBruchstücke in Ihrem Stroh zu bekommen.
Die Barkeeper verwenden immer noch frische und lokale Produkte, aber sie verfeinern jeden Aspekt der Cocktails, in denen sie verwendet werden, von der Temperatur über die Textur bis hin zum physischen Format.In dieser Diashow schauen wir uns einige der modernsten Geräte an, die in Bars auf der ganzen Welt eingesetzt werden.
Bei der Herstellung von Infusionen, Tinkturen, Bitter und Sirup setzen Barkeeper feste Zutaten in Flüssigkeiten ein und filtern sie dann aus.Herkömmliche Filtrationsmethoden umfassen den Einsatz von Sieben, Käsetüchern und Kaffeefiltern, aber zunehmend wenden sich Barkeeper zu anspruchsvolleren Techniken wie Buchner Trichter, und zumindest in diesem Fall, ein Weinfilter namens Mini-Jet.Das Gerät wird hergestellt, um Weißweine zu filtern, um Sediment zu entfernen und den wine tools zu polieren.Bei Canon in Seattle nutzt der Besitzer Jamie Boudreau den Mini-Jet, um Infusionen und Bitter zu filtern, die er an der Bar zum Verkauf anbietet und in den Getränken verwendet.Boudreau sagt, dass dieser Filter sowohl schneller als auch gründlicher als andere Filter ist, obwohl er nur die gröbsten verfügbaren Filterpads verwendet, um Sediment unter Beibehaltung des Geschmacks zu entfernen.Derzeit macht er drei verschiedene Bitter: Kirsche, Rhabarber und eine Rekonstruktion einer seit langem bestehenden Marke namens Boker's Bitters.Diese werden in einer Reihe von Getränken verwendet, einschließlich der Fighattan mit Feigengetränktem Bourbon und Boker's Bitters.
Die Artesian hat die beste bar set der Welt in 2013 für das zweite Jahr hintereinander aufgestellt, sie umarmt Opulenz in ihrem Cocktailprogramm, serviert Getränke wie eine, die mit einem schwebenden Duft-Ballon über dem Getränk kommt, und eine andere inspiriert von The Picture of Dorian Gray, die hinter einem Spiegel serviert wird, so dass Sie sich ansehen müssen, während Sie es trinken.Sogar das ice bucket in Artesian ist schick, speziell für die Bar mit einer Computer Numerical Control (CNC) Maschine wie diese geschnitzt.Sie verwenden diese Maschinen, um sowohl runde Eiskugeln aus Blöcken zu schnitzen, als auch um Logos auf große Eispucks zu prägen.Diese Pucks schwimmen auf den Getränken, die in ihren riesigen Cocktailgläsern serviert werden.
Viele Bars und Restaurants wachsen jetzt ihre eigenen Kräuter, Früchte und Gemüse auf den Dachgärten, aber das ist wahrscheinlich eine Herausforderung während der Winter in Kanada.Der Besitzer der Victoria Bar Shawn Soole hat in Little Jumbo ein hydroponisches System installiert, um das ganze Jahr über Produkte anzubauen.Das Gerät ist mit dem Hauptwassersystem verbunden und hat Lichter an Zeitschaltern, so dass sie, sobald sie die richtige Sequenz herausgefunden haben, es einstellen und vergessen können (bis sie hineingreifen müssen und etwas für die Getränke pflücken müssen).Sie haben Minze angebaut, um Getränke wie die traditionelle Mint Julep und die Pontarlier Julep, plus Basilikum zu machen Gin-Basil Smashes, ein Cocktail, der ein beliebtes Sommergetränk in Deutschland ist.Während sie mit der Maschine immer noch die richtigen Wachstumszeiten wählen, sagt Soole, er wolle Verbena, Zitronenbaum und Thymian für zukünftige Cocktails anbauen.
In den letzten Jahren sind Cocktails auf dem Wasserhahn zu einem Trend geworden, weil Kunden ausgefallene, leckere Cocktails mit frischen, hochwertigen Zutaten wollen, aber sie wollen nicht auf 20-Minuten warten, bis Barkeeper in jedem Getränk Tropfen und Spritzen von 12-verschiedenen Dingen hinzufügen.Mit Cocktails können Barkeeper eine große Charge auf einmal machen und sie so schnell wie möglich ein Bier servieren.Und obwohl viele Bars jetzt ein oder zwei auf dem Wasserhahn anbieten, haben sie in Tavernita alle Arten von Bier und wine glass, plus zehn Cocktails auf dem Wasserhahn, und diese beinhalten Zutaten wie Paprika-getränkter RoggenWhisky, wine rack-Birnensirup und BBQ-Bitter.Der einfachste Weg, einen Cocktail am Wasserhahn zu servieren, ist, ein inertes Gas wie Stickstoff zu verwenden und es durch die Linie zu schieben, wie man es für Wein am Wasserhahn tun würde.Aber das funktioniert nur bei nicht-carbonatierten Getränken wie Netronis und Manhattans (und Sangria auch bei Tavernita).Hier gibt es auch Cocktails, die karboniert sind, wie einen Gin & Tonic mit hausgemachtem Tonikum und einen Cachaca-Drink mit Trauben-Soda.Die Fässer werden alle gekühlt und von ihrem „batchologen“ zubereitet, deren Aufgabe es ist, mit Präparaten sehr anspruchsvoll zu sein und die Inhaltsstoffe nicht nach Volumen, sondern nach Gewicht zu messen.Sie berechnen sogar die Verdünnung im Voraus und fügen dem Fass Wasser hinzu, je nachdem, ob das Getränk auf Eis serviert wird oder nicht.
Viele Barkeeper haben sich an Sous-vide Kochtechniken gewandt, um die Infusionen zu beschleunigen und ihre Konsistenz zwischen den Chargen zu verbessern.Die Methode umfasst vakuumdichtende Inhaltsstoffe (und Schnaps) in Plastiktüten und deren Beheizung bei niedriger, kontrollierter Temperatur.Bei Pint Jigger, wahrscheinlich der fortschrittlichsten Cocktailbar Hawaii, heiratet der Besitzer Dave Newman die Sous-Vide-Küche mit einer anderen, neu bekannten Technik: Fass-Aging.Statt einen Cocktail zu mischen und ihn für einen Monat oder mehr in einem kleinen Fass zu altern, kauft Newman Jack Daniel s Holzschips zum Rauchen (aus Whisky-Fässern hergestellt) und legt sie stattdessen mit den Cocktailzutaten in Mason-Gläsern in das Sous-vide-Bad.Die Getränke nehmen holzige Aromen und eine seidigere Textur nach nur zwei oder drei Tagen im Sous-vide auf, anstatt die gleiche Anzahl von Monaten in einem Fass.Newman hat mit dieser Technik flattergealterte Cocktails gemacht, darunter Boulevardier, Martini, Dark N Stormy und Vieux Carre.
"Wahrscheinlich siebzig Prozent der Cocktails auf der Speisekarte haben etwas, das durch die Zentrifuge gegangen ist", sagt Dave Arnold von Booker && Dax.Die Zentrifuge wird mit einer erstaunlich großen Anzahl von Zutaten verwendet, und diese Zutaten werden durch die Zentrifuge, je nachdem, wie sie in Cocktails verwendet werden.Schließlich wird die Zentrifuge einfach verwendet, um Zutaten nach ihrem Gewicht zu trennen.In einigen Fällen kann dies als wirklich guter Filter funktionieren, wie wenn Arnold Mandel-Sirup-Orgeat macht oder das Sediment der Bitterstoffe filtert.Er verwendet auch die Zentrifuge bei der Klärung von Säften und bei der Trennung von "milchpwed" Spirituosen.Zur Klarstellung Säfte Arnold die Frucht oder die Zitrusfrüchte, fügt Enzyme hinzu, um sie weiter zu zerlegen (manchmal auch mit Weinfiniermitteln), dann spinnt er sie in der Zentrifuge, um die Flüssigkeiten von den Feststoffen zu trennen.Er sagt, das macht nicht nur schöne klare Säfte, sondern erhöht auch den Ertrag über nur mit einem Entsafter allein.Zum Waschen von Milch fügt er Milch zu Spirituosen hinzu und trennt dann die zerkleinerten Milchstückchen.Es klingt widerlich, aber Getränke wie klassische Milk Punches unterziehen diesen Prozess auch, nur nicht in einer Zentrifuge).Die milchgewaschenen Geister haben eine weiche Textur, und wenn sie in Cocktails geschüttelt werden, erzeugen sie einen schönen Schaumkopf.Die gereinigten Säfte werden in Rührgetränken (in der Regel werden alle Getränke mit Säften geschüttelt, aber diese brauchen sie nicht mehr) sowie in kohlensäurehaltigen Cocktails verwendet, wo sie besser die Fizz des Getränks behalten.
Ein Rotary Verdampfer ist eine Miniatur, die immer noch typisch für Chemiker ist, die einige Barkeeper in letzter Zeit verwendet haben.In den meisten Ländern ist es illegal, die Ausrüstung zu verwenden, um selbstgemachten Wodka zu produzieren, zum Beispiel (zum Teil weil die Regierung Steuern auf den Alkohol erheben will), aber in einigen Ländern nutzen Barkeeper es, um High-Level-Infusionen, Reduktionen und andere Flüssigkeiten zu schaffen.Sowohl in einem traditionellen Still als auch in einem Rotavap werden Mischungen durch Verdunstung durch unterschiedliche Siedepunkte (in der Regel trennen Alkohol von Wasser) getrennt, aber in einem Rotavap kann dies bei weit niedrigeren Temperaturen getan werden, um empfindlichere Aromen herauszuziehen und zu vermeiden, sie zu verbrennen.Als der führende molekulare Mixologe Tony Conigliaro von der Bar ohne Namen sagt in seinem Buch The Cocktail Lab,"Was ich an dem Rotavar liebe, ist, dass es eines der kompliziertesten Geräte des Labors ist, aber die daraus hergestellten Produkte sind unglaublich poetisch." Conigliaro betreibt dies immer noch, um Dinge wie Pferdradische Wodka, die in einer Bloody Mary verwendet wird, und eine Portweinreduktion, die in einem Getränk mit dunklem Rum und Grenadine verwendet wird.Es kann auch verwendet werden, um alkoholfreie Zutaten wie Orangenblütenwasser, das in einem Ramos Gin Fizz verwendet wird.
Ein Super-Kühler, oder das zirkulierende Bad, kühlt schnell die Zutaten ab, die in seine super-kalte Mischung aus Ethanol und Wasser getaucht werden.In Chicago's Progressive Aviary schwimmen sie etwa acht Minuten lang mit Wasser-Ballons im Bad.Das ist genug, um eine Schicht Wasser im Ballon einzufrieren.Dann knallen sie den Ballon, stechen ein kleines Loch in die Eiskugel, um das flüssige Wasser in der Mitte zu saugen, und ersetzen es durch einen Cocktail wie den Vieux Carre.Dann, um etwas extra schick zu machen, knacken die Trinker diesen Cocktail "in den Felsen" mit einer Schleuder am Tisch.) Staff hier auch tauchen hohe Collins-Gläser mit Wasser in das Bad, damit ein Ärmel aus Eis um die Innenseite erfrieren kann.Anschließend spülen sie den restlichen slush ab und werden mit einem eisgesäumten Glas, in dem sie kohlensäurehaltige Cocktails servieren, gelassen, da die Blasen so sprudelnd bleiben.Sehen Sie sich dieses coole Video des Eisprogramms an.Foto von Christian Seel

You may have noticed that women basic socks aren’t what they used to be. Think back: for a long time socks were just something you used to cover your feet. Possibly black, probably ankle-height and definitely an afterthought. Socks are now an important part of your outfit at the least, the making of an outfit at most.

Socks have become an area of diplomacy and woke-signalling – the Canadian prime minister Justin Trudeau is perhaps the biggest name to use socks in this way, choosing pointedly themed ones for public occasions. Or a telling insight into a political mind: Boris Johnson was criticised recently for not washing his lucky socks, emblazoned with a ruler of the Neo-Assyrian empire King Ashurbanipal, often enough.
Socks are such a basic item that they're easy to take for granted...and leave on the floor, shove under beds, or lose to the dryer monster. (It happens to the best of us.) But socks actually deserve mad props for keeping our wiggly and sometimes stinky feet dry, warm, and free from blisters, so in honor of National Sock Day, here's a little history of how they became a thing and some guidelines on what kind to wear and when…or not.

Until the 17th century, men basic socks were called stockings, but according to Wikipedia, the modern English word sock (first recorded in 1690, btw), evolved from the Old English socc which evolved from the Latin soccus…"a lightweight shoe worn by ancient Greek and Roman comic actors." Socks are worn on our feet (mostly) and come in various lengths, fabrics, colors, patterns, and styles, depending on their intended purpose, i.e. thick wool socks for skiing, thin wool dress socks for business, and short white socks for running. But the first socks were actually made from leather or matted animal hair – called "piloi" in 8th century BC Greece. A thousand years later in the 2nd century AD, the Romans were the first ones to sew woven fabrics together and make fitted socks ("udones").

The oldest surviving socks are a red-orange pair from between 250 AD and 420 AD that were excavated from Oxyrhynchus on the Nile in Egypt. They were made with the nålebinding technique, which means "knotless netting" and uses a single thread...the precursor to modern-day knitting and crochet. And they have split toes specifically for—gasp!—wearing with sandals. (Which the ancient Romans and Greeks did more or less exclusively, so they get a pass on any fashion judgement.) Speaking of Egypt, socks were so important that alongside all of the gold and jewels, King Tut's tomb supposedly contained several pairs made from linen.

In the Middle Ages, socks were brightly-colored and started becoming more of a fashion statement. As trousers got shorter over the next few centuries, socks got longer…and more expensive. So expensive, in fact, that by the end of the first millennia, socks were actually a status symbol among the nobility, and had also become highly ornamental. #FunFact: a fancy design that's embroidered or woven on each side or the outer side of a sock beginning at the ankle is called a clock. Who knew?

As societies progressed, so did basketball function socks, and they were made from wool, silk, and cotton, depending on a person's economic class (nobles = silk; peasants = wool). Besides being a display of wealth, socks served an important utilitarian purpose since even nobles faced harsh conditions at times. (Indoor heating wasn't a thing until the 20th century, so keeping those piggies warm was essential…frostbite didn't care if someone was wealthy.) Peasants especially were exposed to the elements way more than we are today and needed to protect their feet from the wet and cold. (They also bathed less often, so if you think your teen's basketball socks are stinky, just imagine the funk of a 16th century pair.)

Socks were so critical to life that mending them—called "darning"—was a very important skill. Cold feet led to frostbite which could lead to gangrene which could lead to death, so when a sock had a hole in it, it most definitely got fixed! As early as the 12th century, the heel of a sock was the last part made, which made it easier to replace when it wore out…a very common practice. Sock owners took their maintenance seriously.

The knitting machine's arrival on the scene in 1589 was a game-changer since six pairs of football function socks could be made in the time it took to create one previously, but socks were still hand-knit alongside the machines for another couple hundred years. A tiny percentage are still made that way today. Socks were historically held up with ribbons or ties or by garters since elastic wasn't a thing yet. Until Jedediah Strut's Derby Rib machine in 1758, that is, but it was so expensive that it took almost two more centuries before more socks were held up by elastic than garters. To put it in perspective, in 1899 England, a pair of socks sold for the equivalent of $15 today…a LOT back then.

The next biggest thing to happen to socks was—drumroll please—the 1938 introduction of…nylon. The blended fabric was born, and synthetics changed the sock world, along with the rest of it. With socks now being made from recycled plastics, their evolution has come full circle in the last 80 years. The most common blends today include cotton, wool, and polyester or nylon, but socks are also made with silk, spandex, bamboo, and other fabrics.

Another big moment in the evolution of socks was globalizing production. In 2011, the Datang district of Zhuji in the Zhejiang Province of China was known as "Sock City." Why? Because it was producing 8 billion pairs of socks each year, which was a third of the world's annual total. Finding accurate sales numbers is challenging but suffice to say that BILLIONS of pairs of socks are sold each year for even more billions of dollars, the competition is fierce, and socks are almost as high-tech as electronics in some facets of their engineering.

The Rules of Socks
We've established that socks come in all kinds of fabric configurations and all kinds of styles, some of the common categories being: dress winter floor socks, athletic socks, hiking socks, ski socks, knee socks, tube socks, ankle socks, foot socks, boot socks, novelty socks, booties, slipper socks, tights, and pantyhose. There's no question that with the help of socks, shoes protect your feet from debris, disease, injury, and the elements. But sometimes, it's the outer world that needs to be protected from sweaty or smelly feet. To that end, businesses and venues with dress codes will usually tell you if socks are required (that would be yes 98% of the time). But what about when it's completely up to you? Socially and hygienically, are there times that you should always—or never—wear socks? (That would also be yes.)
Seriously, lost socks are a real and quantifiable phenomenon. But quantum physics theories aside, the average person loses 1,264 socks over his or her lifetime, so where do they GO? One clue is the way that some socks take a detour and mysteriously show up within the next couple of laundry loads. So, they weren't really lost, they were stuck in a fitted sheet, stuck to a sweater, stuck under the upper rim of the washing machine basket, or otherwise occupied for a bit. The socks that are actually lost could be under the bed, they could have fallen out of your gym bag in the locker room or landed in a gutter when you were walking, someone might have thrown a sock away because it had a hole and they didn't know how to darn it, they could be stuck to something neatly folded in a drawer somewhere, or they could actually be IN the washing machine in a hose, filter, or other part, especially if they're small, and ditto with the dryer! (Yes, really...certain models can literally eat your socks.)

La primera vez que camine detrás de la barra, notará todas las wine tools y dispositivos parpadeantes de la barra que pueden ser desconcertantes.En la parte superior de cada botella hay cucharas en espiral, palos de madera en forma elegante, agitadores en todas partes, medidores de nombres extraños, mezcladores, exprimidores, mazos, embudos y pequeños respiraderos.
¿Dónde quieres empezar?
¿Entender estas herramientas y su uso?
¿Invertir en su propio equipo para que pueda practicar haciendo cócteles deliciosos en casa?
Esto es lo que veremos en este artículo.Vamos a introducir las herramientas y equipos más importantes que los camareros utilizan para hacer bebidas maravillosas, y lo que usted necesita para empezar.
Empezaremos con las herramientas básicas del barman.Estas son las cosas que cada camarero debe llevar consigo en el trabajo.También son útiles para las personas que les gusta beber en casa.
Luego pasamos a un equipo de cóctel específico.Estas son las herramientas que usted debe invertir. Usted puede practicar en casa, celebrar cócteles, o preparar una buena bebida para usted después de un día de trabajo duro.
En el mundo real y en línea, usted puede comprar herramientas de bar en varios lugares.En primer lugar, considere comprar a un minorista local (si lo hay).En las ciudades más grandes, algunos minoristas se centrarán en bares y equipos de cocina.Usted debe ser capaz de comprar herramientas de alta calidad allí.
Para estar en línea, considere los siguientes minoristas:
Amazon.com – hoy en día, usted puede obtener casi cualquier cosa de Amazon.
Cocktailkit.com.au – especialmente útil para los consumidores australianos.Tienen una serie de equipos de alta calidad, a un precio razonable, con sede en Australia.
Productos de bar set. Com – cuenta con una amplia gama de instalaciones de bar, cristalería, cocina y bar familiar.¡Compruebe cuidadosamente su sitio web, que es impresionante!
Hay muy pocas herramientas de bar y cada camarero debe llevar consigo en el trabajo.En casi todos los hoteles en los que he trabajado, la gente quiere que los camareros los tengan y los lleven.
Si no lo haces, parece poco profesional y perezoso.Así que si eres camarero, hazte un favor y compra estos artículos lo antes posible.No puedes (y no deberías) esperar que un bar te ofrezca estos servicios.
Además, si usted está buscando un trabajo como camarero, usted debe llevar estos artículos a su clase de prueba.
Las herramientas básicas de camarero en servicio incluyen:
Hoja de Bar - se utiliza para abrir rápidamente botellas de cerveza y otros usos temporales.Nunca se sabe cuándo o qué hoja será útil.
Cuchillo de wine rack / amigo del camarero / llave de vino - para abrir botellas de corcho, botellas de cerveza y otros usos temporales.
2 bolígrafos – llevar al menos 2 bolígrafos.Uno puede usarlo, uno en caso de que pierdas el primero, dejará de funcionar, o tendrás que dejarlo.
Encendedor - incluso si no eres fumador, el encendedor es útil.Para los cócteles, se utilizan para encender el entusiasmo naranja o para encender a los tiradores.En el bar, se pueden utilizar para encender velas o ayudar a los fumadores necesitados.
Si desea practicar un camarero en casa, construir su propio bar familiar, o celebrar una fiesta de cócteles, estas herramientas no le llevarán lejos.
Claro, puedes encender cerveza y wine glass, encender velas y jugar a la Cruz de suma cero, pero si te vas allí, será un cóctel bastante malo.
Así que si realmente quieres hacer cócteles, tienes que invertir en equipos de cóctel.
He dividido este dispositivo en dos categorías."Lujo" de lo esencial y no esencial.
Lo más básico es que usted debe invertir en bartender tools y equipos de bar tan pronto como sea posible.Usted será capaz de utilizar estas herramientas para hacer una variedad de cócteles deliciosos, incluso si se trata de una List a minimalista.
Los artículos "de lujo" no esenciales son herramientas "bien poseídas" o que pueden ser útiles pero que pueden ser reemplazados por artículos de la lista de "necesidades".Cuando empezaste, no eran necesarios.
Un buen cuchillo formará parte de cualquier herramienta de mezcla sólida.Lo usarás todo el tiempo para cortar las raciones, limones y Lima, y cualquier fruta o verdura que finalmente aparecerá en tu cóctel.No hay nada peor que tratar de empuñar un cuchillo contundente y frágil, así que invertir en un buen cuchillo.
La tabla de cortar es una herramienta que no necesita usar la cabeza cuando está cortando.Necesitas algo para cortar, y las tablas de cortar son más higiénicas que los escritorios.También ayudará a mantener su cuchillo afilado durante más tiempo.
El hielo es la última cosa que la gente que acaba de llegar a un camarero quiere hacer.Esto se da por sentado y nunca se considera.Pero el hielo es uno de los ingredientes más importantes para hacer cócteles.Enfría su bebida y diluye el alcohol - una característica básica de un cóctel sabroso.
¡Así que necesitas herramientas para usar el poder del hielo!
Primero, necesitas un cubo de hielo para que no tengas que correr de ida y vuelta de la nevera.
Segundo, necesitas una cuchara de hielo.Trata de no usar tus manos para conseguir hielo.No es higiénico.¡Hagas lo que hagas, No uses un vaso!Los trozos de vidrio pueden romperse en hielo y terminar en la bebida de alguien.Es peligroso...
Por lo tanto, invertir en una cuchara de hielo: -).
Si no tienes una cuchara de hielo, puedes usar tu jarra de Boston como una cuchara de hielo temporal.Véase Boston Shaker infra.
JIG es un pequeño dispositivo de medición utilizado por los camareros detrás del bar.Se utilizan para medir con precisión los ingredientes de un cóctel para que pueda mantener el equilibrio.
Cuando empiece a trabajar, se recomienda encarecidamente el uso de jigs.Verter "latas" gratis es preciso y ciertamente más rápido, pero por eso la mayoría de los bares de cócteles prefieren usar jigs.Este es el método más fiable para medir con precisión el líquido en un vaso.
Aunque he sido camarero durante tanto tiempo & he trabajado en un bar gratuito, mi patrón predeterminado es usar jigs cada vez que hago cócteles.
El Decantador rápido es el respiradero que se encuentra al final de la botella del bar.Pueden ayudarle a controlar el flujo de vertido de la botella y medir su volumen de vertido libre con mayor precisión.En resumen, ayudan a acelerar el proceso de fabricación de bebidas.
No necesariamente llamo a la barra de casa de las aves de velocidad "esencias", porque usted puede simplemente medir con precisión con un cabrestante.Pero son esenciales detrás del bar.Si su objetivo es convertirse en un camarero, entonces sin ellos, la velocidad de la bebida será demasiado lenta, y será mejor que se acostumbre a ellos ahora.
Boston Shaker es un kit de vibración de dos piezas.Uno es más pequeño que el otro, así que puedes golpearlos juntos para formar un sello apretado, y cuando lo sacudes, el líquido no salpica en ninguna parte.
Casi todos los camareros del planeta usan el agitador de Boston como su herramienta preferida.Son rápidos, fáciles de usar, fáciles de filtrar, y pueden ser utilizados como sustitutos de cucharas de hielo o como contenedores de mezcla para mezclar cócteles.
Cuando quiera comprar un traje de Boston Shaker, elija un traje de lata de 2 piezas en lugar de un traje de lata de vidrio.Si usted utiliza un agitador Boston a menudo, el vidrio eventualmente se romperá, por lo que usted puede obtener una mejor relación calidad - precio con una caja de estaño.
Para cualquier tipo de bebedor, cantinero u otra persona, las herramientas de cantinero en servicio son esenciales.Así que asegúrate de conseguir los artículos primero.¡Las personas que beben en casa pueden irse sin cuchillas de bar, pero son baratas, así que cómpralas de todos modos!
Una vez que tenga esto, comience a navegar por la lista de artículos necesarios para hacer cócteles y anote cada elemento de la lista antes de ver artículos de lujo.
Si no tienes equipo, vale la pena considerar comprar un traje de cóctel.Un traje de cóctel robusto y decente como este incluirá la mayoría de los artículos necesarios & tal vez algunos artículos de lujo.
A continuación, usted puede simplemente recoger otras cosas por sí mismo, como la prensa de frutas, accesorios de hielo, tablas de cortar y cuchillos.
Usted debe ser capaz de encontrar todo en línea (Amazon es bueno), pero si le gusta ir de compras usted mismo, trate de encontrar una tienda de suministros de Bar profesional porque tienen un equipo de mejor calidad.
Esa es mi última sugerencia.Cuando invierta en estas herramientas y equipos de bar, elija productos de alta calidad.Confía en mí.Trate de evitar comprar un traje de cóctel de $12 y ver más inversión en alrededor de $100.
Si cuidas de estas herramientas, te beneficiarán de por vida.Y el equipo de camarero de alta calidad se ve mejor y se siente mejor cuando se utiliza.
¡Dicho esto, si usted está en problemas de dinero y necesita practicar sus habilidades de bebida, compre un conjunto de herramientas de $12!Cuando usted gana mucho dinero más tarde como camarero, usted siempre puede invertir en equipos de alta calidad.

Tom owns a production factory. Every day, the factory produces 10 kg of a certain product. Based on his experience, Tom knows that, on average, one trained worker with correct tools could manage to pack and ship out 1 kg of the product daily. Being a predictive man, Tom considers the probability that one worker might get sick. To be on the safe side, he has 11trained workers instead of 10. This helps him prevent an overcapacity situation in the warehouse in the event that one of them is sick or the factory has to increase its production capacity. With his 11 trained workers and correct tools, Tom’s factory operates smoothly every day without trouble.
Now, let’s compare this with the biological wastewater treatment process. The product is the organic load to be removed by means of wastewater treatment; the trained workers and tools are equivalent to the carrier media and biomass in the wastewater treatment process, respectively. Similar to the workers who cannot pack and ship out the products without tools, the carrier MBBR media cannot remove the organic load from the wastewater without biomass.
If one day Tom’s factory starts producing another product that requires a different packing method, he doesn’t dismiss his 11 workers and hire a new group. Rather, he allows his workers time to become familiar with their new working tools. The same applies to biological wastewater treatment: The biomass that grows on the carrier MBBR bio carrier media will gradually adapt itself to remove a different type of organic load or concentration.

In order for Tom to ensure his factory can run smoothly, he needs both skilled workers and a good set of tools for them to use. The lack of either will slow down the packing speed. For biological wastewater treatment with MBBR, the biomass as well as the carrier media that acts as the housing for the bacteria are very important.
A good MBBR carrier media provides more than just a protected habitat for the bacteria to grow; it also ensures that all bacteria that grow on it are sufficiently supplied with nutrients for their metabolism. During the biological treatment process, the bacteria consume dissolved organic substances. Without sufficient nutrients, the growth of the bacteria is hindered, or worse, the bacteria die off. These phenomena will reduce the removal efficiency and lead to an unqualified wastewater discharge. Hence, a proper selection of the carrier media is essential. This decision will affect both the organic removal performance and the cost required to run the plant.
A good MBBR carrier has the following characteristics:
• A large protected surface area to maximize the amount of biomass;
• A porous surface to strengthen the biomass’s adhesion;
• An optimal substrate diffusion depth to ensure the metabolism;
• Wear-resistance for durability.
In terms of treatment, a good MBBR carrier aquaculture filter media ensures that all biomass is active to remove the organic substances from the water. From the user’s perspective, a good MBBR carrier media eases the operation and provides a variety of savings, such as in construction and operation. 
In a wastewater treatment application, the required amount of MBBR carrier media depends on the organic load that needs to be removed by means of the bacteria’s metabolism, the rate of which is influenced by water temperature and the type of substrate.
Although MBBR carrier media might just be a little piece of plastic (or some other material), its role in wastewater treatment is vital to keep the biomass active in order to deliver the best possible organic removal performance. WW
Moving Bed Biofilm Reactors (MBBR) are used increasingly in closed systems for farming of fish. Scaling, i.e. design of units of increasing size, is an important issue in general bio-reactor design since mixing behaviour will differ between small and large scale. Research is mostly performed on small-scale biofilters and the question is to what extent this can be upscaled to a commercial level. Therefore, the objective of this research was to establish the effect of mixing and scale on MBBR performance. The research was done in two major parts; firstly effects of scale-sensitive factors were studied in small reactors. Secondly, performance of these small reactors was then compared to increasingly large reactor sizes, using the same inlet water quality and biofilm.
Firstly, a 200 L MBBR (medium scale) was operated continuously using a synthetic feed solution. Biofilm carriers from this reactor was used for short-term experiments in 0.8 L reactors (small scale) and compared with the performance of the 200 L medium scale reactor. Reactor geometry and superficial air velocity (m h−1) were identical in these experiments. Subsequently, the small reactors were incubated with biofilm carriers from three commercial farms and performance compared with these large scale reactors. In a number of additional experiments the effect of mixing and Total Ammonia Nitrogen (TAN) was tested at small and medium scale.
The results showed that MBBR scale has a significant effect on TAN removal rate. In general, the larger the scale the better the performance. TAN removal (rTAN) at small scale (0.8 L) is about 80% compared to that at medium scale (200 L). The difference between small scale and large scale (>20 m3) is even higher. These findings warrant further studies on whether a plateau is reached in rTAN at a certain scale; a study which will have considerable importance for optimal design and dimensioning of commercial scale RAS. It was further found that superficial air velocity is not a good scaling factor for MBBRs. Upscaling while maintaining geometry implies increasing air injection depth and therefore increased energy input will be required at a comparable superficial air velocity, which is not incorporated in the superficial air velocity term (m h−1). Superficial air velocity and plastic media filling% were found to have a strong effect on mixing time at small scale. An air velocity below a threshold of 5 m h−1 decreased TAN removal at both small and medium scale. Intense mixing at small scale increased TAN removal at low TAN concentration. However, at a high TAN concentration, the small scale MBBR always performed at not more than 80% of the capacity of the medium scale system, irrespective of the mixing conditions. Hence, the capacity of full scale systems will be under-estimated when based solely on small scale experiments.
Suspended particles in recirculating aquaculture systems (RAS) provide surface area that can be colonized by bacteria. More particles accumulate as the intensity of recirculation increases thus potentially increasing the bacterial carrying capacity of the systems. Applying a recent, rapid, culture-independent fluorometric detection method (Bactiquant®) for measuring bacterial activity, the current study explored the relationship between total particle surface area (TSA, derived from the size distribution of particles >5 μm) and bacterial activity in freshwater RAS operated at increasing intensity of recirculation (feed loading from 0.043 to 3.13 kg feed m−3 make-up water). Four independent sets of water samples from different systems were analyzed and compared including samples from: (i) two individual constructed wetlands treating the effluent system water from two commercial, freshwater rainbow trout (Oncorhynchus mykiss) farms of different recirculation intensity; (ii) an 8.5 m3 pilot scale RAS; and (iii) twelve identical, 1.7 m3 pilot scale RAS assigned one of four micro-screen treatments (no micro-screen, 100, 60, or 20 μm mesh size micro-screens) in triplicate. There was a strong, positive, linear correlation (p < 0.05) between TSA and bacterial activity in all systems with low to moderate recirculation intensity (i.e. feed loading ≤1 kg feed m−3 make-up water). However, the relationship apparently ceased to exist in the systems with highest recirculation intensity (feed loading 3.13 kg feed m−3 make-up water; corresponding to 0.32 m3 make-up water kg−1 feed). This was likely due to the accumulation of dissolved nutrients sustaining free-living bacterial populations, and/or accumulation of suspended colloids and fine particles less than 5 μm in diameter, which were not characterized in the study but may provide significant surface area. Hence, the study substantiates that particles in RAS provide surface area supporting bacterial activity, and that particles play a key role in controlling the bacterial carrying capacity at least in less intensive RAS. Applying fast, culture-independent techniques for determining bacterial activity might provide a means for future monitoring and assessment of microbial water quality in aquaculture farming systems.
Microbial water quality in recirculating aquaculture systems (RAS) is important for successful RAS operation but difficult to assess and control. There is a need to identify factors affecting changes in the bacterial dynamics – in terms of abundance and activity – to get the information needed to manage microbial stability in RAS. This study aimed to quantify bacterial activity in the water phase in six identical, pilot scale freshwater RAS stocked with rainbow trout (Oncorhynchus mykiss) during a three months period from start-up. Bacterial activity and dynamics were investigated by the use of a patented method, BactiQuant®. The method relies on the hydrolysis of a fluorescent enzyme-substrate and is a rapid technique for quantifying bacterial enzyme activity in a water sample. The results showed a forty-fold increase in bacterial activity within the first 24 days from start-up. Average BactiQuant® values (BQV) were below 1000 at Day 0 and stabilized around 40,000 BQV after four weeks from start. The study revealed considerable variation in initial BQV levels between identically operated and designed RAS; over time these differences diminished. Total ammonia nitrogen, nitrite and nitrate levels were very similar in all six RAS and were neither related to nor affected by BQV. Chemical oxygen demand (COD) and biological oxygen demand (BOD5) were highly reproducible parameters between RAS with a stable equilibrium dynamic over time. This study showed that bacterial activity was not a straightforward predictable parameter in the water phase as e.g. nitrate-N would be in identical RAS, and showed unexpected sudden changes/fluctuations within specific RAS. However, a bacterial activity stabilization phase was observed as systems matured and reached equilibrium, suggesting a successive transition from fragile to robust microbial community compositions.

Lotion pumps are used in a wide variety of liquid products – we’re talking about soaps, body wash, hand creams, and the likes. Products with lotion pump dispensers are more noticeable and preferable by consumers, and why wouldn’t they? Lotion pumps are incredibly convenient to use, plus they last long.
If you are thinking of buying a lotion pump dispenser but doesn’t know how to check which is better and which is not, then you bumped in the right article. We’re going to list down six factors that you have to look at to land on the ideal pump closure for your containers. More than that, we made an additional list of six lotion pumps from YEHPAK that you have to check out. So, let’s go!
See our checklist that you need to weigh in when deciding which variety of lotion pump to buy.
Material Composition
The material composition of the lotion pump will determine the durability of the equipment. Aside from the commonly used polypropylene (PP) plastic, there are quite a lot of varieties you can select from, such as ceramic, steel, and glass materials.
Before you opt for a lotion pump dispenser, you must first evaluate where do you plan to use it. Will it be for personal use? For commercial use? Or for business consumption? If it is for private or household access, then ceramic or steel type would be excellent for aesthetics and longevity. If it is for commercial use, steel is preferable for durability. Last but not least, if it is for business, then plastic and glass type is your best option since they are lightweight and cost-efficient.
Neck Size
It is essential to know what is the precision of the neck size you are looking for. Some variables include 20/410, 20/415, 24/410, and 24/415 – and these sizes can almost match to various bottleneck sizes. Through this, you can create a perfect bottle–dispenser match, while trying your selected pump into different bottles of your product.
Tube Length
You also have to check the tube length. Note that the plastic tube used inside the container can be cut to the ideal size of the chamber. Besides, the diameter of the tube will depend on the thickness of the liquid inside the bottle. So choose wisely. 
Pump Dosage
0.5ml,0.12ml, 0.28ml, 1.4ml, and 2.0ml are just some of the popular dosing amount variables. Choosing your airless pump bottles dose will rely on product specifications, expected usage, cost of the product, or bottle capacity.
Color
Since dispensing pumps are typically made of plastic in the manufacturing process, it would be effortless to add color along the process. This can be arranged easily if a client prefers dispensing pump customization in bulk. Frequently, they can also be colored with an aluminum sheath, which gives a compelling look and defines a luxury edge of a particular product. 
Price
Every person in business knows that quality is essential, so if you opt for a good quality product, then you better be prepared to pay more. However, if the type of quality is none of your concern, then you can always choose for an economical pump dispenser – as long as it provides its purpose, then you won’t have a problem.

Plastic lotion pumps, one of the most popular dispensing methods for viscous (thick liquid) products in the personal care and beauty industry, come in all shapes and sizes. When used as designed, pumps dispense the right amount of product time after time. But have you ever wondered what goes in a lotion pump to makes it work? While there are hundreds of different designs in the market today, the basic principle is the same, and Packaging Crash Course took apart one of these lotion pumps to give you an overview of these components, and how they contribute to the overall functionality of pumping the product from the bottle to your hand.
Generally speaking, a lotion pump consists of the following components :
Actuator : An actuator, or the pump head, is what the consumer presses down to pump the product out of the container. The actuator is often made of PP plastic and can have many different designs - and often come with a up-lock or down-lock features to prevent accidental output,. This is one of the component designs that can set one pump apart from another when it comes to the exterior design, it is also the part where ergonomics play a role in consumer satisfaction.
Closure : The component that screws the entire assembly onto the neck finish of the bottle. It is identified with the common neck finish destination such as 28-410, 33-400. Often made of PP plastic, it is often designed with a rib side or smooth side surface. In certain cases a shiny metal overshell can be installed to give the lotion pump a high-end, elegant look.
A lotion pump acts much like a air suction device that draws the product from the bottle to the consumer's hand despite the law of gravity telling it do the opposite. When the consumer presses down on the actuator, the piston moves to compress the spring and the upward air pressure draws the ball upwards, along with the product inside, into the dip tube and subsequently the chamber. As the user releases the actuator, the spring returns the piston and actuator into it's up position, and the ball is returned to it's resting position, sealing the chamber and preventing the liquid product from flowing back down into the bottle. This initial cycle is called "priming". When the user presses down on the actuator again, the product that is already in the chamber will be drawn from the chamber, through the stem and actuator, and dispense out of the pump and onto the consumer's hand. If the pump has a bigger chamber (common for high output pumps), it may require additional priming before the product will be dispensed through the actuator.
Lotion Pump Output
The output of a plastic foam pump is often measured in cc (or ml). Commonly in the range of 0.5 to 4cc, with some larger pumps with bigger chambers and longer piston / spring components having output up to 8cc. Many manufacturers have multiple output options for each of their lotion pump offerings, giving the product marketer full control of dosage. For more information about pump output, please see our other Quick Question Monday article here.

Choosing the right fluid dispensing pump for a given application is critical. Whether it’s accuracy and precision or the need to perform for millions of cycles, understanding the most suitable types of pumps available is the first step. This article describes several pumps commonly used for medical manufacturing applications. It examines their advantages and disadvantages. In addition, it discusses how to maximize accuracy by minimizing fluid slip, an important factor in the design of any positive displacement pump. It also looks at the importance of testing the fluid prior to determining what pump is best for the application.
There are essentially two types of drive systems that control fluid delivery using positive displacement. Linear drive systems and rotary drive systems. Positive displacement pumping refers to a pump that retracts in a cavity to generate volume on the suction side and extends into the cavity displacing the fluid on the discharge. This is a constant for each cycle. Both linear and rotary positive displacement pumps provide exceptional accuracy and precision. However, each method has its’ advantages and disadvantages.
Calibration. In a rotary application, the volume of displacement is a factor of the pump angle relative to the motor axis. Once the volume is calibrated, the pump module can be locked into position. The displacement is adjustable so it should be checked to confirm that calibration is still within specification. In a linear application, mechanical calibration is not required. The pump module is set in a static location, and volume is determined by how far the piston retracts in the cavity. There is no mechanical set point to change volume; only software is used to adjust this parameter.
Cycle Time. Rotary pumps can produce faster dispenses because the rotary valving motion and linear displacement motion are performed simultaneously. A single cycle is controlled by one revolution of the motor. Multiple revolutions will produce larger volumes based on the pumps fixed volume. Cycle time and the ability to produce a more constant flow rate (based on pump revolutions) are the rotary pumps’ strengths. The dispense profile of a rotary pump includes pulsations which are due to the sinusoidal waveform. This offers the unique advantage of firing off small volumes of fluid very quickly. An example of a rotary application would be dispensing microliter range dots of fluid onto a substrate passing through a high-speed automation system.
By contrast, a linear pump must retract from the suction port to draw fluid into the chamber valve to the discharge port, and then eject the fluid. In general, larger volumes require more time, depending on pump size. The linear dispense creates a flat dispense profile with no pulsation throughout the entire chamber capacity of the pump module. If more volume or a longer dispense is required, two pumps may be run out of phase so that one pump is discharging while the other is on the intake stroke. An example of a linear application would be dispensing a constant line over a distance, such as a diagnostic reagent, or precisely filling a substrate with slow absorption rates. Continuous web applications are ideal for this tandem approach.

An international group of scientists from India and Russia has created edible food transparent films for packaging fruits, vegetables, poultry, meat, and seafood. Films consist of natural ingredients, they are safe for health and the environment. In addition, films are water-soluble and dissolve by almost 90% in 24 hours. Description of the research and results of experiments are published in the Journal of Food Engineering.
"We have created three types of food super clear films based on the well-known naturally occurring seaweed biopolymer sodium alginate," said Rammohan Aluru, senior researcher Organic synthesis laboratory at Ural Federal University and co-author of the paper. "Its molecules have film-forming properties. Sodium alginate is an auspicious carbohydrate macromolecule that has the potential film-forming properties upon hydrolysis and abundantly existed in cell walls as a mixture of various salts. The greatest advantage of sodium alginate is that it performs as liquid-gel in an aqueous medium."
Alginate molecules were cross-linked with a natural antioxidant ferulic acid. It makes the film not only strong, but also homogeneous, more rigid, and prolongs the life of the products.
"Food stays fresh longer due to the antioxidant components that slow down the oxidation processes," said Grigory Zyryanov, professor of the Department of Organic and Biomolecular Chemistry at Ural Federal University. "In addition, we can add to the films natural antiviral agents, which will also extend the shelf life of food. Garlic, turmeric, and ginger contain compounds that may prevent the spread of the viruses."
According to the authors, no special equipment for the production of films is required. On an industrial scale, it can be created by food products and films manufacturers.
"It can also be produced at a polymer production plant. The only condition is that it must meet the standards that apply to food production. And if an inexhaustible source of algae the ocean is nearby it will be quite simple to create such films," said Grigory Zyryanov.

A plastic embossed film having a random embossed matte finish is provided. The random embossed matte film may be wound very easily into rolls and the roll contour achieved has superior uniformity. In addition, the film provides relatively equal tape adhesion and gloss properties on both sides which make it especially suitable for use in articles such as disposable diapers or underpads. Another advantageous property that renders it especially suitable for diaper conversion operations is its very low degree of edge curl. The clear embossed film provides a totally different appearance as compared to conventional diaper films in that the overall appearance is a dull matte finish but nonetheless having slight sparkles of brilliance throughout the surface, and it further provides a softer feel.

As the name suggests, decorative film is aesthetically pleasing. This type of window film can serve two purposes: it can make the workplace not as dull, plus it can attract customers from the outside.
Decorative film can come in a number of patterns and colors, as well as opacity (such as gradients), and some places even let you make custom designs. You can include window film in your branding and create something that’s truly unique.
Since you can control the opacity of decorative film, not only can it brighten up your workplace, but it can also be an interesting type of privacy film. So instead of looking at plain window film every day, your employees can enjoy looking at interesting patterns.

Plasticiser (US: plasticizers) have been used for decades to make toys soft, flexible and safe by replacing or protecting sharp edges and avoiding brittleness which could result in a choking hazard. The use of some ortho-phthalates has been restricted in the European Union since December 1999. In 2005 the temporary restrictions were formalised in the Marketing and Use Directive which in turn was incorporated into Annex XVII of REACH. DEHP, DBP and BBP are restricted in all toys and childcare articles based on their reproductive properties. DINP, DIDP and DNOP are restricted in toys and childcare articles which can be placed in the mouth based on ECHA and RAC not being able to exclude a risk (due to mild liver effects seen at high doses in rat studies). The precise restrictions can be found in REACH Annex XVII (Paragraphs 51 and 52).

Wind turbines work on a simple principle: instead of using electricity to make wind—like a fan—vertical wind turbines use wind to make electricity. Wind turns the propeller-like blades of a turbine around a rotor, which spins a generator, which creates electricity.

Wind is a form of solar energy caused by a combination of three concurrent events:
1. The sun unevenly heating the atmosphere
2 .Irregularities of the earth's surface
3. The rotation of the earth. 
Wind flow patterns and speeds vary greatly across the United States and are modified by bodies of water, vegetation, and differences in terrain. Humans use this wind flow, or motion energy, for many purposes: sailing, flying a kite, and even generating electricity.
The terms "wind energy" and "wind power" both describe the process by which the wind is used to generate mechanical power or electricity. This mechanical power can be used for specific tasks (such as grinding grain or pumping water) or a generator can convert this mechanical power into electricity.
A horizontal wind turbine turns wind energy into electricity using the aerodynamic force from the rotor blades, which work like an airplane wing or helicopter rotor blade. When wind flows across the blade, the air pressure on one side of the blade decreases. The difference in air pressure across the two sides of the blade creates both lift and drag. The force of the lift is stronger than the drag and this causes the rotor to spin. The rotor connects to the generator, either directly (if it’s a direct drive turbine) or through a shaft and a series of gears (a gearbox) that speed up the rotation and allow for a physically smaller generator. This translation of aerodynamic force to rotation of a generator creates electricity. 

Permanent magnets have been used to provide the magnetic field in small to medium sized generators for many years. The use of these in large renewable energy (RE)generators may offer performance advantages for future utility-scale generators.
Large (MW sized) permanent magnet generators (PMGs) are mainly found in the wind turbine sector today, but are not confined to this area. PMGs offer a number of advantages to the generator field and are being used in applications from standby plant to hydro generators. The PMG is finding particular application in renewable energy systems, where reduced size and higher efficiency give an advantage. The ability to find application in both low speed and high speed generators is accelerating the use of this type of equipment.

Solar panel connectors are crucial items in the installation of solar generation systems. The connector speeds up the installation and makes it relatively easy by ensuring continuity between cables that connect the modules in the solar array. This allows the current to flow from the solar panel to the solar charge controller, into the solar inverter, and then power every appliance at the home.
The solar cable connector plugged at the end of each wire is the main one responsible for simplifying modular installations for solar systems. By using these connectors, a solar installer can reconfigure the modules when increasing the size of the system, installing modules in parallel or series to achieve the desired array.
Using the right mc4 solar connector is important for the wiring of photovoltaic (PV) modules with other components in the system, especially when using a combiner box for larger systems. In this article, we will dive into the basics of solar connectors, you will learn about the different types of solar connectors, the differences among them, and many other important aspects that you should know.
Photovoltaic wire, also known as PV wire, is a single-conductor wire used to connect the panels of a photovoltaic electric energy system. A solar cable is the interconnection cable used in photovoltaic power generation. Solar cables interconnect solar panels and other electrical components of a photovoltaic system. Solar cables are designed to be ultraviolet resistant and weather resistant.

HEATING ELEMENTS
About 5000 to 7000 furnaces for sintering zirconia are produced every year at the moment. The numbers are rising. There are two different heating element types that are installed in the dental furnaces on the market to achieve the extremely high temperatures, usually in excess of 1400°C (2552°F). By far the largest share of the furnaces on the market is built with molybdenum disilicide (MoSi2) heating elements. In some few cases, silicon carbide (SiC) heating elements will be used. These two element types differ in their properties in addition to the entirely different basic materials.
SiC heating elements are usually used up to a temperature of 1530°C (2786°F) as recommended by the furnace manufacturer. A firing cycle will take several hours. MoSi₂ heating elements can be used up to a temperature of 1750°C (3182°F), depending on the quality and furnace type. The maximum application temperature of these heating elements therefore is clearly above that of SiC heating elements. Additionally, the surface load, which means the power (W) that can be emitted per square centimeter (cm2) is more than twice that of SiC, at above 25 W/cm2. This permits much faster heating-up rates, to much higher application temperatures. Heating to 1550°C (2822°F) in less than 15 minutes is possible.
MolyCom®-Hyper 1800 (MoSi2) heating elements that have been used on the international dental market since 2005 have turned out to be much longer-lived than SiC elements in continuous tests and according to the experience of various furnace manufacturers. SiC elements usually need to be replaced after just a few hundred cycles due to the strong change of resistance, which corresponds to a service life of approx. 1-2 years at common use. MolyCom®-Hyper 1800 elements in contrast have been operated for more than 2500 cycles without any failure or need for exchange. Exchange of the defective element is usually sufficient in MoSi2 heating elements. In contrast to this, all parts of the SiC elements must be exchanged in one due to the strongly impaired resistance.

If we additionally compare the chemical analysis of the heating elements, the standard heating elements show a much higher degree of contamination, in particular by iron oxide. No contamination could be measured at use of the MolyCom®-Hyper 1800 elements up to a temperature of 1630°C (2966°F). No contamination was measured for MolyCom®-Hyper 1800 Super Clean elements up to 1680°C (3056°F).
Additionally, a contaminated zirconia sample on the surface was analyzed with a secondary ion mass spectrometry (SIMS). As the analysis shows, increased contents of iron oxide could be documented in the sample up to a depth of 0.15 μm. While the degree of contamination is very low, it has a considerable visual effect. The vapor pressures of many different oxides at the surface temperatures of the MoSi2 heating elements in the furnace were additionally calculated with Fact Sage. 

Among the ceramic materials, silicon nitride ceramics possess good overall performance (e.g., high hardness, high strength, low density, low thermal conductivity, low chemical activity, and high wear resistance), which promotes these applied as rolling bearing, machine tools, sliding bearing in water pumps.

Aluminum titanate has outstanding properties that make it ideally suited for applications involving molten aluminum, including complete resistance to wetting by aluminum alloys, total gas impermeability, and a very low thermal expansion coefficient. This material offers a longer service life and higher reliability when compared to cast iron, calcium silicate or fused silica components. All riser/stalk tubes are 100% leak-down tested, and parts are available with gasketing and ceramic foam filters to provide complete assemblies.

Alumina ceramic is an industrial ceramic that has high hardness, is long wearing, and can only be formed by diamond grinding. It is manufactured from bauxite and can be shaped using injection molding, die pressing, isostatic pressing, slip casting, and extrusion.

Reaction bonded silicon carbide has excellent wear, impact, and chemical resistance. The strength of RBSC is almost 50% greater than that of most nitride bonded silicon carbides. It can be formed into a variety of shapes, including cone and sleeve shapes, as well as more complex engineered pieces designed for equipment involved in the processing of raw materials.

Ceramic fiber paper is a must-have for those who work in the manufacturing industry. It’s a type of the high-temperature insulated paper that’s integral to many manufacturing functions. For one thing, ceramic fiber paper has a huge variety of applications — whether it’s protecting gaskets (like rope gaskets) from high temperatures or providing insulation — and there’s a range of grades and thermal conductivity, depending on what’s needed. If you’re looking to purchase ceramic fiber paper, we’re your best bet — we’ll discuss some of the benefits and applications that you might not have expected out of this material and what you should expect when ordering and handling it. 
One of the major benefits of using ceramic fiber paper is that it has a low thermal conductivity and doesn’t store much heat. It’s also thermal shock resistant and is resistant to most chemicals, which means it has a low corrosion rate. It’s great if you’re looking to die-cut or use automatic stamping and has high dielectric strength as well. 
Another benefit to this type of paper is that it’s lightweight and uniform in its structure, which makes it a great type of insulation. It’s also flexible and fire-resistant! 

Before purchasing a server cabinet or server rack it is import ant to understand the difference between the different products that are available. This will ensure that you purchase exactly what you need.

Server Cabinets
Server Rack Cabinets such as the 42u Server Cabinet are generally nineteen inches wide by industry standards. This products is mostly used to install servers, UPS ES, monitors or similar equipment. Server rack cabinets, for the most part, are twenty-four inches in width, and thirty six inches deep. Some companies offer other measurement options to meet customers’ needs, however. Floor standing network server rack cabinets usually have a perforated front and rear. This feature offers ventilation for the equipment being housed. This is crucial to providing a safe environment for this type of equipment which generates a good deal of heat.

Network Cabinets
Network cabinets or Network Racks are often confused with server cabinets. However, there is a difference. Network cabinets are generally used for the storage of routers, patch panels, switches and a wide variety of networking equipment as well as networking accessories. In most cases a network cabinet will be far shallower than a server rack cabinet, generally measuring in at less than thirty one inches deep. Outdoor network cabinets will sometimes have glass or a strong plastic front door. Network cabinets also generally do not have perforated enclosures. The type of equipment generally housed in network cabinets does not generate the same amount of heat as that housed inside a server rack.
Because one product can not fulfill the needs of all office equipment storage, it may become necessary to do a thorough evaluation of the type of equipment being used, or that will be used, in order to make the most informed purchasing decision. In many cases, office spaces will require the use of both a server rack and a networking cabinet in order to house the various equipment that will be used there.
It is important to note, that improperly housing heat generating equipment is dangerous. This could cause damage to your equipment, or worse could become a fire hazard due to the temperatures which some servers can generate. Good rack dealers will help you decide which product is best for you.

Monitoring can be done either at the incomer of the PDU sockets in terms of the total power being drawn from the whole PDU, or it can be focused on an individual device’s demands from the socket. The latter provides a greater granularity for analysis but not all meters have the same accuracy, it may range from one to five percent, so it is worth investigating into the technical specifications.
PDU electronics also consume power at levels which can be significant, especially in a large scale data centre, given that it can range from as little as six to 60 watts. If intelligent PDUs are installed in a 200 rack data centre with dual PDUs in the rack then their power consumption could be as little as 2.4kW or as much as 24kW.
The switching function allows users to remotely shutdown individual sockets and to ‘hard boot’ any device that is connected to it. It is worth checking which type of switch device (or relay) is within the PDU construction, either monostable or bi-stable. The monostable needs a permanent supply of power to change state and stay there. Bringing it back means removing the power. 
The bi-stable needs to be pulsed with electricity to change state and pulsed again to come back. Bi-stable therefore uses less power than monostable, which can again be significant in terms of the aggregate consumption from a lot of sockets.
