A Cornelius keg (also known as a Corny keg or soda keg) is a stainless steel canister (keg) initially utilized as containers by the soft drink business. They can be used to store and dispense carbonated or nitrogenated fluids. Cornelius kegs were initially created by Cornelius, Inc.
In the keg, completely created soda is stored below pressure just like standard cans and bottles. The soda is known as “premix” in the business, as compared to “postmix” bag-in-box (BiB) packages which can be concentrated syrup. BiB soda costs less but needs a higher-high quality water source and well-calibrated dispenser. Premix soda costs much more and requires much more space, but can be applied anyplace, and also the tools are easier and less expensive.
When the primary method of providing and dispensing soda, today kegs are mostly outdated within the soft drinks industry. Cornelius kegs are now widely used for homebrewed beer and other home made beverages including soft drinks or nitro cold make coffee.
Pin lock (left) and ball lock quick-link fittings, which mate towards the keg plug-ins. Hoses connect to the threaded flare fittings observed at the top. Fittings are colour-coded for if they connect to the gas (grey) or liquid (dark or metal) port; these specimens are both for fluid outlines.
A Cornelius keg is a stainless steel cylinder that can hold a maximum of 130 PSI. There are three openings in the keg: a big main opening for cleaning and satisfying, and 2 plug-ins for pressurizing and dispensing.
The main opening is used for satisfying and cleaning the keg and is also large enough to allow getting to inside for hand cleaning. The separate metal cover for your main opening up provides a clamp mechanism that shuts and seals the cover against the keg having a big rubber O-ring; this design helps to ensure that the cover can simply be opened up if the keg is not pressurized. The cover also provides a stress relief device that is usually recognized by a circular pull-ring (like a key diamond ring). The relief device can be manually opened to release the stress within the keg; in the case of an unsafe overpressure in the keg, the comfort device automatically opens to prevent the hazard of bursting the tube.
The two ports are used to dispense the beverage, one for “gasoline in”, and the other for “liquid out”. Two metal or plastic material tubes are connected to the ports within the keg. The “gasoline in” dock has a brief tube, not getting to the fluid. The “liquid out” port includes a long pipe (a “drop tube”) which gets to the bottom of the keg. Headspace gas stress (usually co2 and quite often nitrogen forced into the “gasoline in” port) pushes the drink from the base of the keg the pipe and after that from the “fluid out” port linked to a tap or any other dispensing device.
Fast-link articles are affixed to the plug-ins. The posts have integral poppet valves which open up when a hose with an suitable fitting is connected to them. The fast-link articles and fixtures come in two mechanical types, namely pin lock and ball lock, which can be not exchangeable. Traditionally, pin lock kegs were utilized mainly by the Coca-Cola company, while ball lock kegs were used mainly by Pepsi. Pin lock kegs utilize a bayonet mount consisting of radial pins around the articles and corresponding slot machines around the fixtures. When the connector is attached, these pins hold it in position. The “gasoline in” post has two pins, while the “liquid out” has 3, rendering it impossible to unintentionally change the gasoline and liquid hoses (which will harmlessly bring about fractional co2 bubbling up via uhdgpy drink, while gas but no consume will be dispensed).
Ball-lock kegs have flared ridges on the exterior of the posts, which can be gripped by little metal balls within the connections. The ridges will vary dimensions: a reduced ridge for that gas article, along with a larger ridge for that liquid article. In comparison to pin hair, this may not be as simple to visually distinguish, so additional visible cues are occasionally supplied: the gas and fluid posts may use various coloured rubber gaskets, the gas post may have little notches to differentiate it, and the kegs them selves may tag the plug-ins as “IN” and “OUT” or may use a hit to tag one in the plug-ins. In contrast to pin hair, it really is possible to mistakenly force a ball lock fitted on the wrong post (normally the fluid connector onto the “gasoline in” article), after which it is quite difficult to get rid of.
