Jockey Box
A jockey box is an insulated container containing ice and water, as well as a long coil of hollow tubing. The device is used to cool beverages being served on tap in temporary locations. One end of the coiled tube in the box is fitted to the external supply of the beverage to be served (often moved from the supply container by gas pressure, as in the case of beer in kegs, and the other end is attached to taps for serving the beverage, which are often integrated into the box itself. Filling the jockey box with ice and water cools the coiled tubing, and when the beverage flows through the tube, the beverage is cooled to a temperature just above freezing, even if it was at room temperature before it entered the box. This allows cold drinks to be served on tap in temporary and outdoor venues. Apart from the coil and taps, the jockey box resembles a cool box. Some jockey boxes force the liquid through a solid cold plate rather than a coil of tubing (see Alternative Portable Cooler Dis ...

Drink
A drink or beverage is a liquid intended for human consumption. In addition to their basic function of satisfying thirst, drinks play important roles in human culture. Common types of drinks include plain drinking water, milk, juice, smoothies and soft drinks. Traditionally warm beverages include coffee, tea, and hot chocolate. Caffeinated drinks that contain the stimulant caffeine have a long history. In addition, alcoholic drinks such as wine, beer, and liquor, which contain the drug ethanol, have been part of human culture for more than 8,000 years. Non-alcoholic drinks often signify drinks that would normally contain alcohol, such as beer, wine and cocktails, but are made with a sufficiently low concentration of alcohol by volume. The category includes drinks that have undergone an alcohol removal process such as non-alcoholic beers and de-alcoholized wines. Biology When the human body becomes dehydrated, a person experiences thirst. This craving of fluids results ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Partial Pressure
In a mixture of gases, each constituent gas has a partial pressure which is the notional pressure of that constituent gas as if it alone occupied the entire volume of the original mixture at the same temperature. The total pressure of an ideal gas mixture is the sum of the partial pressures of the gases in the mixture ( Dalton's Law). The partial pressure of a gas is a measure of thermodynamic activity of the gas's molecules. Gases dissolve, diffuse, and react according to their partial pressures but not according to their concentrations in gas mixtures or liquids. This general property of gases is also true in chemical reactions of gases in biology. For example, the necessary amount of oxygen for human respiration, and the amount that is toxic, is set by the partial pressure of oxygen alone. This is true across a very wide range of different concentrations of oxygen present in various inhaled breathing gases or dissolved in blood; consequently, mixture ratios, like that of breat ...

Keg Beer
Draught beer, also spelt draft, is beer served from a cask or keg rather than from a bottle or can. Draught beer served from a pressurised keg is also known as Name Until Joseph Bramah patented the beer engine in 1785, beer was served directly from the barrel and carried to the customer. The Old English ' ("carry; pull") developed into a series of related words including ''drag'', ''draw'', and ''draught''. By the time Bramah's beer pumps became popular, the use of the term ''draught'' to refer to the acts of serving or drinking beer was well established and transferred easily to beer served via the hand pumps. In time, the word came to be restricted to only such beer. The usual spelling is now "draught" in the United Kingdom, Ireland, Australia, and New Zealand and more commonly "draft" in North America, although it can be spelt either way. Regardless of spelling, the word is pronounced or depending on the region the speaker is from. Canned draught is beer served fr ...

Freezing
Freezing is a phase transition where a liquid turns into a solid when its temperature is lowered below its freezing point. In accordance with the internationally established definition, freezing means the solidification phase change of a liquid or the liquid content of a substance, usually due to cooling. For most substances, the melting and freezing points are the same temperature; however, certain substances possess differing solid-liquid transition temperatures. For example, agar displays a hysteresis in its melting point and freezing point. It melts at 85 °C (185 °F) and solidifies from 32 °C to 40 °C (89.6 °F to 104 °F). Crystallization Most liquids freeze by crystallization, formation of crystalline solid from the uniform liquid. This is a first-order thermodynamic phase transition, which means that as long as solid and liquid coexist, the temperature of the whole system remains very nearly equal to the melting point due to the slow re ...

Room Temperature
Colloquially, "room temperature" is a range of air temperatures that most people prefer for indoor settings. It feels comfortable to a person when they are wearing typical indoor clothing. Human comfort can extend beyond this range depending on humidity, air circulation and other factors. Food or beverages may be served at ''room temperature'', meaning neither heated nor cooled. In certain fields, like science and engineering, and within a particular context, ''room temperature'' can mean different agreed-upon ranges. In contrast, ''ambient temperature'' is the actual temperature, as measured by a thermometer, of the air (or other medium and surroundings) in any particular place. The ambient temperature (e.g. an unheated room in winter) may be very different from an ideal ''room temperature''. Comfort temperatures ''The American Heritage Dictionary of the English Language'' identifies room temperature as around , while the ''Oxford English Dictionary'' states that it is "co ...

Cool Box
A cooler, portable ice chest, ice box, cool box, chilly bin (in New Zealand), or esky (Australia) is an insulated box used to keep food or drink cool. Ice cubes are most commonly placed in it to help the contents inside stay cool. Ice packs are sometimes used, as they either contain the melting water inside, or have a gel sealed inside that stays cold longer than plain ice (absorbing heat as it changes phase). Coolers are often taken on picnics, and on vacation or holiday. Where summers are hot, they may also be used just for getting cold groceries home from the store, such as keeping ice cream from melting in a hot automobile. Even without adding ice, this can be helpful, particularly if the trip home will be lengthy. Some coolers have built-in cupholders in the lid. They are usually made with interior and exterior shells of plastic, with a hard foam in between. They come in sizes from small personal ones to large family ones with wheels. Disposable ones are made solel ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Glove Compartment
A glove compartment or glove box is a compartment built into the dashboard of an automobile, located over the front-seat passenger's footwell, and often used for miscellaneous storage. The name derives from the original purpose of the compartment, to store driving gloves. They were sometimes in a box on the floorboard near the driver, hence the word "glove box". In most vehicles, the glove compartment closes with a latch, with the option of being locked with a key (often desirable when using valet service, when parking with the convertible top down, or when the compartment contains a mechanism to open the trunk). Other local names In Barbados, South Africa, and Zimbabwe, as well as parts of southern Minnesota and northwest Wyoming, the glove compartment is commonly referred to as a "cubby-hole" or "cubby". It is also occasionally called a '' jockey box'', especially in the upper Rocky Mountain states in the United States, such as Idaho. History An early innovation was the ...

Food Storage Containers
Food storage containers are widespread in use throughout the world and have probably been in use since the first human civilizations. Early civilizations In early civilizations cereal grains such as maize, wheat, barley etc. were stored in large airy buildings, often raised up from the ground to reduce infestation by pests and vermin. Ancient Egyptian and early Hebrew writings include reference to such buildings and their successors can still be seen in use in less developed countries and regions. Smaller quantities of food were stored in baskets made from woven grasses or leaves and such designs have remained in use to the present day. In more recent times but prior to the invention of the refrigerator many food products were stored in the home as preserves or pickles, often in heat sealed jars such as Kilner jars Modern containers In the modern developed world, a very wide range of food packaging and containers is now available made from many materials. ;Plastic contain ...
