A Cornelius keg (also called a Corny keg or soda keg) is a stainless steel canister (keg) initially used as containers by the soft drink industry. They can be used to store and distribute carbonated or nitrogenated liquids. Cornelius kegs were initially created by Cornelius, Inc.
Inside the keg, fully created soda is kept below stress just like standard containers and bottles. The soft drinks is known as “premix” in the business, as compared to “postmix” handbag-in-box (BiB) packages that are concentrated syrup. BiB soda is less expensive but needs a higher-quality water resource and well-adjusted dispenser. Premix soft drinks costs more and requires more space, but can be applied anyplace, as well as the devices are easier and cheaper.
When the primary way of delivering and dispensing soft drinks, today kegs are largely obsolete in the soft drinks business. Cornelius kegs are actually widely used for homebrewed beer and other home made drinks like 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 seen at the top. Fittings are color-coded for whether or not they get connected to the gasoline (grey) or liquid (black or steel) dock; these specimens both are for liquid outlines.
A Cornelius keg is a stainless tube that can hold a maximum of 130 PSI. You will find three opportunities within the keg: a big central hole 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 permit reaching within for hand scrubbing. The individual steel lid for your main opening up offers a clamp mechanism that shuts and seals the cover against the keg using a big rubberized O-ring; this style helps to ensure that the lid can only be opened when the keg will not be pressurized. The lid offers a stress relief valve that is certainly typically identified by a circular draw-diamond ring (like a key ring). The relief valve can be manually opened up to discharge pressure in the keg; in case of an unsafe overpressure in the keg, the relief device automatically opens up to prevent the risk of bursting the cylinder.
The 2 plug-ins are utilized to distribute the drink, one for “gas in”, and the other for “liquid out”. Two metal or plastic pipes are attached to the ports on the inside of the keg. The “gas in” dock has a short tube, not reaching the fluid. The “fluid out” port features a long pipe (a “dip tube”) which gets to the base of the keg. Headspace gasoline stress (usually co2 and often nitrogen compelled in to the “gasoline in” port) forces the drink from the base of the keg up the tube and after that out of the “fluid out” port attached to a tap or some other dispensing device.
Fast-connect posts are attached to the plug-ins. The posts have integral poppet valves which open up each time a garden hose having an suitable fitted is attached to them. The quick-link articles and fixtures can be found in two mechanical varieties, namely pin lock and ball lock, which can be not interchangeable. Traditionally, pin lock kegs were used mainly through the Coca-Cola company, whilst ball lock kegs were utilized primarily by Pepsi. Pin lock kegs use a bayonet install composed of radial pins on the articles and related slots around the fixtures. When the connector is connected, these pins hold it in position. The “gasoline in” post has two pins, as the “liquid out” has 3, which makes it impossible to accidentally change the gas and liquid hoses (which will harmlessly result in carbon dioxide effervescent up via uhdgpy consume, while gas but no consume would be dispensed).
Ball-lock kegs have flared ridges externally of the articles, that are gripped by little metal balls inside the connections. The ridges are different sizes: a smaller ridge for the gasoline article, and a larger ridge for your fluid article. In comparison to pin hair, this may not be as easy to aesthetically differentiate, so extra visual cues are often provided: the gas and liquid articles may use different coloured rubber gaskets, the gasoline post may have small notches to differentiate it, and the kegs themselves may tag the plug-ins as “IN” and “OUT” or may possess a hit to tag one in the ports. Unlike pin hair, it is possible to erroneously force a ball lock fitting on the wrong post (usually the liquid connector onto the “gas in” post), then it really is very difficult to remove.
