The principle of liquid nitrogen food quick freezing:

food quick freezing generally refers to the use of modern freezing technology, using liquid nitrogen as the refrigerant to reduce the temperature of the food to the expected low temperature below its freezing point. All or most of the moisture contained in the food will form reasonable tiny ice crystals along with the heat dissipation inside the food. At the same time, the liquid nitrogen quick-freezer freezes part of the free water of the cells and reduces the water activity without any preservatives and additives, and at the same time, the food nutrition is preserved to a great extent. It has the advantages of delicious, convenient, healthy, hygienic, nutritious and affordable original food
