Mechanical refrigeration relies on circulating chemical refrigerants to lower temperatures. Cryogenic refrigeration , on the other hand, uses liquid gas, which comes into direct contact with food for cooling. The latter is a powerful refrigeration technique with several advantages for food businesses.  What Are the Benefits of Cryogenic Refrigeration?  1. Higher Efficiency in Freezing  Image-by-pixelshot Mechanical refrigeration gradually lowers the temperature to achieve full freezing. Even in the most efficient systems, it takes hours or even days to freeze a product completely. The mechanical properties of liquid gas, for example, liquid nitrogen allow complete freezing of food products within minutes of exposure. Also, liquid nitrogen has a lower freezing temperature, whic...
