By far, the cryogenic freezing of food products is the hallmark of low temperature applications for the commodity that is carbon dioxide (CO2).
My personal experience with respect to low temperature applications for the commodity have been the lion’s share of the merchant work, in the past with the former AmeriGas, CO2 Division, by far. The same applies today when I work with independent gas companies outside of North America, such as in Africa and the Middle East, when developing and instructing such companies in the art of CO2 usage in food processing, cryogenic freezing, and temperature reduction.
Cryogenic freezing usage often represents the majority of new developments which these companies put into action. Since near 40% of North America’s merchant usage, on average, is found in food processing, it is impressive to find applications primarily in temperature reduction and cryogenic freezing.
