Cornelius Keg
A Cornelius keg (also known as a Corny keg or soda keg) is a stainless steel canister ( keg) originally used as containers by the soft drink industry. They can be used to store and dispense carbonated or nitrogenated liquids. Cornelius kegs were originally made by Cornelius, Inc. In the keg, fully made soda is stored under pressure just like standard cans and bottles. The soda is referred to as " premix" in the industry, as compared to "postmix" bag-in-box (BiB) packages which are concentrated syrup. BiB soda is cheaper but requires a high-quality water source and well-calibrated dispenser. Premix soda costs more and takes up more space, but can be used anywhere, and the equipment is simpler and cheaper. Once the main method of delivering and dispensing soda, today kegs are largely obsolete in the soda industry. Cornelius kegs are now widely used for homebrewed beer and other homemade beverages such as soda or nitro cold brew coffee. Description A Cornelius keg is a stain ...

Ullage
Ullage or headspace is the unfilled space in a container, particularly with a liquid. Etymology The word ''ullage'' comes from the Latin word ''oculus'', used by the Romans to refer to a barrel cork hole. This word was, in turn, taken in medieval French as ''oeil'', from which a verb ''ouiller'' was created, meaning to fill a barrel to full capacity. Around 1300, the word ''ouillage'' was created by the Normans to refer to the amount of liquid needed to fill a barrel to capacity. Alcoholic beverages In winemaking, ''ullage'' came to refer to any amount by which a barrel is unfilled, perhaps because some of the contents have been used. It is also applied to the unfilled air space at the top of a bottle of wine, which in this case is essential to allow for expansion of the contents as the temperature changes. By further extension, in brewing and beer retail, ''ullage'' is the residue of beer left in a barrel that has been emptied. When calculating tax returns and the like, license ...

Kegerator
Kegerator, a portmanteau of ''keg'' and ''refrigerator'', a refrigerator that has been designed or altered to store and dispense kegs. The kegerator keeps the keg in a refrigerated environment and uses CO2 to pressurize and dispense beverages from the keg. This keeps the contents of the keg fresh and carbonated for an extended period of time, on average up to 60 days. Kegerators are specifically designed and available for both commercial and residential use, however, a common refrigerator can be reconfigured into a kegerator with a kegerator conversion kit. Not all standard refrigerators have enough room for a keg, so kegerators are designed in a manner that will allow one or more kegs to fit inside along with the dispensing system. Kegerators are typically used to dispense draft beer, but are also gaining popularity for dispensing wine, cold brew coffee, and kombucha with certain modifications. Components The kegerator contains the following components: * Stainless steel keg ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Threads Per Inch
A screw thread, often shortened to thread, is a helical structure used to convert between rotational and linear movement or force. A screw thread is a ridge wrapped around a cylinder or cone in the form of a helix, with the former being called a ''straight'' thread and the latter called a ''tapered'' thread. A screw thread is the essential feature of the screw as a simple machine and also as a threaded fastener. The mechanical advantage of a screw thread depends on its ''lead'', which is the linear distance the screw travels in one revolution. In most applications, the lead of a screw thread is chosen so that friction is sufficient to prevent linear motion being converted to rotary, that is so the screw does not slip even when linear force is applied, as long as no external rotational force is present. This characteristic is essential to the vast majority of its uses. The tightening of a fastener's screw thread is comparable to driving a wedge into a gap until it sticks fast thr ...

Bayonet Mount
A bayonet mount (mainly as a method of mechanical attachment, such as fitting a lens to a camera using a matching lens mount) or bayonet connector (for electrical use) is a fastening mechanism consisting of a cylindrical male side with one or more radial pins, and a female receptor with matching L-shaped slot(s) and with spring(s) to keep the two parts locked together. The slots are shaped like a capital letter L with serif (a short upward segment at the end of the horizontal arm); the pin slides into the vertical arm of the L, rotates across the horizontal arm, then is pushed slightly upwards into the short vertical "serif" by the spring; the connector is no longer free to rotate unless pushed down against the spring until the pin is out of the "serif". The bayonet mount is the standard light bulb fitting in the United Kingdom and in many countries that were members of the British Empire including Pakistan, Australia, Hong Kong, Fiji India, Sri Lanka, Ireland, and ...

Pepsi
Pepsi is a carbonated soft drink manufactured by PepsiCo. Originally created and developed in 1893 by Caleb Bradham and introduced as Brad's Drink, it was renamed as Pepsi-Cola in 1898, and then shortened to Pepsi in 1961. History Pepsi was first invented in 1893 as "Brad's Drink" by Caleb Bradham, who sold the drink at his drugstore in New Bern, North Carolina. It was renamed Pepsi-Cola in 1898, "Pepsi" because it was advertised to relieve dyspepsia (indigestion) and "Cola" referring to the cola flavor. Some have also suggested that "Pepsi" may have been a reference to the drink aiding digestion like the digestive enzyme pepsin, but pepsin itself was never used as an ingredient to Pepsi-Cola. The original recipe also included sugar and vanilla. Bradham sought to create a fountain drink that was appealing and would aid in digestion and boost energy. In 1903, Bradham moved the bottling of Pepsi from his drugstore to a rented warehouse. That year, Bradham sold 7,968 gal ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Coca-Cola
Coca-Cola, or Coke, is a carbonated soft drink manufactured by the Coca-Cola Company. Originally marketed as a temperance drink and intended as a patent medicine, it was invented in the late 19th century by John Stith Pemberton in Atlanta, Georgia. In 1888, Pemberton sold Coca-Cola's ownership rights to Asa Griggs Candler, a businessman, whose marketing tactics led Coca-Cola to its dominance of the global soft-drink market throughout the 20th and 21st century. The drink's name refers to two of its original ingredients: coca leaves and kola nuts (a source of caffeine). The current formula of Coca-Cola remains a closely guarded trade secret; however, a variety of reported recipes and experimental recreations have been published. The secrecy around the formula has been used by Coca-Cola in its marketing as only a handful of anonymous employees know the formula. The drink has inspired imitators and created a whole classification of soft drink: colas. The Coca-Cola Company p ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Poppet Valves
A poppet valve (also called mushroom valve) is a valve typically used to control the timing and quantity of gas or vapor flow into an engine. It consists of a hole or open-ended chamber, usually round or oval in cross-section, and a plug, usually a disk shape on the end of a shaft known as a valve stem. The working end of this plug, the valve face, is typically ground at a 45° bevel to seal against a corresponding valve seat ground into the rim of the chamber being sealed. The shaft travels through a valve guide to maintain its alignment. A pressure differential on either side of the valve can assist or impair its performance. In exhaust applications higher pressure against the valve helps to seal it, and in intake applications lower pressure helps open it. The poppet valve was invented in 1833 by American E.A.G. Young of the Newcastle and Frenchtown Railroad. Young had patented his idea, but the Patent Office fire of 1836 destroyed all records of it. Etymology The word ...

Nitrogen
Nitrogen is the chemical element with the symbol N and atomic number 7. Nitrogen is a nonmetal and the lightest member of group 15 of the periodic table, often called the pnictogens. It is a common element in the universe, estimated at seventh in total abundance in the Milky Way and the Solar System. At standard temperature and pressure, two atoms of the element bond to form N2, a colorless and odorless diatomic gas. N2 forms about 78% of Earth's atmosphere, making it the most abundant uncombined element. Nitrogen occurs in all organisms, primarily in amino acids (and thus proteins), in the nucleic acids ( DNA and RNA) and in the energy transfer molecule adenosine triphosphate. The human body contains about 3% nitrogen by mass, the fourth most abundant element in the body after oxygen, carbon, and hydrogen. The nitrogen cycle describes the movement of the element from the air, into the biosphere and organic compounds, then back into the atmosphere. Many indus ...

Carbon Dioxide
Carbon dioxide ( chemical formula ) is a chemical compound made up of molecules that each have one carbon atom covalently double bonded to two oxygen atoms. It is found in the gas state at room temperature. In the air, carbon dioxide is transparent to visible light but absorbs infrared radiation, acting as a greenhouse gas. It is a trace gas in Earth's atmosphere at 421 parts per million (ppm), or about 0.04% by volume (as of May 2022), having risen from pre-industrial levels of 280 ppm. Burning fossil fuels is the primary cause of these increased CO2 concentrations and also the primary cause of climate change.IPCC (2022Summary for policy makersiClimate Change 2022: Mitigation of Climate Change.

Pound Per Square Inch
The pound per square inch or, more accurately, pound-force per square inch (symbol: lbf/in2; abbreviation: psi) is a unit of pressure or of stress based on avoirdupois units. It is the pressure resulting from a force of one pound-force applied to an area of one square inch. In SI units, 1 psi is approximately equal to 6895 Pa. Pounds per square inch absolute (psia) is used to make it clear that the pressure is relative to a vacuum rather than the ambient atmospheric pressure. Since atmospheric pressure at sea level is around , this will be added to any pressure reading made in air at sea level. The converse is pounds per square inch gauge (psig), indicating that the pressure is relative to atmospheric pressure. For example, a bicycle tire pumped up to 65 psig in a local atmospheric pressure at sea level (14.7 psi) will have a pressure of 79.7 psia (14.7 psi + 65 psi). When gauge pressure is referenced to something other than ambient atmospheric pressure, then the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Soft Drink
A soft drink (see § Terminology for other names) is a 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 ... that usually contains water (often carbonated), a sweetener, and a natural and/or Artificial Flavoring, artificial flavoring. The sweetener may be a sugar, high-fructose corn syrup, fruit juice, a sugar substitute (in the case of diet drink, ''diet drinks''), or some combination of these. Soft drinks may also contain caffeine, Food coloring, colorings, preservatives, and/or other ingredients. Soft drinks are called "soft" in contrast with "Hard drink, hard" alcoholic drinks. Small amounts of alcohol (drug), alcohol may be present in a soft drink, but the Alcohol by volume, alcohol content must be less than 0.5% of the total volume of the drink in many countries and ...
