Problems solved by technology
Large ice crystals can damage the cell wall, causing cytoplasmic efflux, which in turn leads to a reduction in food quality
At the same time, when the food is frozen, the freezing speed decreases from the surface to the center, and the uneven distribution of the freezing speed can easily lead to a decrease in the quality of the food.
Frozen for a long time, not only the large ice crystals will destroy the tissue structure, but also the cells cannot return to their original shape after thawing, and a large amount of cell fluid will be lost, which will affect the flavor and quality of the food, and even make it inedible

Description
technical field [0001] The invention relates to the technical field of freezing equipment, in particular to a liquid quick-freezing equipment. Background technique [0002] Traditional refrigeration equipment uses air as the heat transfer carrier. This method is limited by the low thermal conductivity of air, and the freezing time of food is longer. During the freezing process, the extracellular solution first produces ice crystals, and under the action of vapor pressure, the water in the cells flows to the ice crystals outside the cells, and larger ice crystals are formed at this time, and the distribution is uneven. As the protein denatures, the cell membrane loses water more easily, which further increases the volume of the ice crystal. Large ice crystals will damage the cell wall, causing cytoplasmic efflux, which in turn will cause a reduction in food quality. At the same time, when the food is frozen, the freezing speed decreases from the surface to the center, and t...
