SLUSH MACHINE

Frozen uncarbonated beverages are made by freezing a non-carbonated juice or other liquid. Machines for producing these do not require a pressure chamber, and as a result, they are much cheaper and easier to maintain. There are variations including frozen carbonated beverages, typified by the Slush, which are made by freezing a carbonated drink. Machines for producing these are complicated and expensive, and notably require a carbon dioxide supply. They make a very fine and 'dry' slush. There are also frozen coffee beverages  as well as more conventional slush drinks. There are also "instant" slush drinks formed via supercooling.
