What are the advantages of liquid nitrogen quick freezing machine?

The quick-freezing machine has the following advantages: short quick-freezing time, long fresh-keeping time, good food quality, sanitation and environmental protection, and avoiding the formation of large ice crystals between cells. Reduce the extravasation of water in cells, reduce the loss of juice during thawing, significantly shorten the contact time of concentrated solute in cell tissues with food tissues, colloids and various components, minimize the harm of concentration, quickly reduce food below the temperature of microbial growth activities, and favorably resist the growth of microorganisms and their biochemical reactions. Liquid quick-freezing and fresh-keeping equipment for aquatic products: quick-freezing (only takes a few minutes to ten minutes), with high efficiency and low operating cost. Due to the adoption of ultra-low temperature freezing technology, the product can be thoroughly and effectively sterilized during quick freezing. The quick-frozen products can be directly put into the refrigerator for cold storage, so there is no need to worry about the proliferation of bacteria attached to food and destroying it. ?
