The advantages of cryogenic freezing

Cryogenic freezing (cryofreezing) is a method of freezing in which the food is exposed to an atmosphere below -60 °C through direct contact with liquified gases such as nitrogen or carbon dioxide.

Cryogenic technologies are generally used for food processing and food preservation many industries are use cryogenic technology in this time for better food quality and good products.

Compared to conventional freezing techniques, the cryogenic method has the following advantages: rapid freezing, inhibition of bacterial growth, limited dehydration, considerable reduction of quantitative losses, good retention of original quality attributes, maintenance of the appearance and taste of the food.

Cryogenic freezing helps minimize dehydration of the frozen items, while retaining item quality, texture, color, and, in the case of food items, flavor.

Using cryogenic systems one can avoid the large investment required for a compression refrigeration system, using only liquefied cryogenic fluid delivery from time to time.

Other advantages of cryogenic freezing: less energy requirement, low capital investment, minimal space requirement, maintenance space requirements, simplicity of operation, continuous in-line freezing, minimum off stream time.
