Frozen carbonated beverage

A frozen carbonated beverage (FCB) is a mixture of flavored sugar syrup, carbon dioxide, and water that is frozen by a custom machine creating a drink comprising a fine slush of suspended ice crystals, with liquid. The final ice crystal concentration changes from 10% to 50%. It dispenses on a type of beverage and a trade mark of each company producing FCB. Some common FCBs are the Slurpee, the ICEE, and the Froster and also known as Fizzy Slush Machines.

The FCB machine was invented by Omar Knedlik, then the owner of a Dairy Queen franchise. In the late 1950s, his restaurant lacked a soda fountain. Instead, he stored soda in his freezer. His customers loved the slushy drinks, so Knedlik tried to capture them with a machine. By the mid 1960s, about 300 machines had been manufactured. In 1965 7-Eleven licensed the machine, and began selling the Slurpee.

How a FCB machine works

The back-end of a FCB machine is very similar to a regular soda fountain. Concentrated flavor syrups are mixed with filtered water, then carbonated. This mixture is then injected into a cylinder surrounded by freezer coils. The mixture freezes to the wall of the cylinder, then is scraped off by a rotating dasher, which also keeps the mixture uniformly mixed. FCB machines will often freeze to a temperature well below the freezing point of water, but the combination of pressure (up to 40 p.s.i.), sugar, and the constant stirring prevent the mass from freezing solid.

Differences between FCBs and other drinks

FCB machines are distinctive from other slush drink machines in that they require a pressure chamber and a carbon dioxide source. Many modern non-carbonated slush machines use a spiral-shaped plastic dasher to scrape crystals off a freezing cylinder, often integrated into a clear hopper. This product is often much 'wetter' than a true FCB. On the other hand, non-carbonated machines are much simpler and less expensive, and so they are more common. A non-carbonated slush machine can be purchased for well under $2000, and rented for less than $100/day or from £65.00 per day in the UK for a single head machine. By comparison, FCB machines often must have a dedicated service staff.
