Technical advantages of tunnel freezer

　　 Tunnel-type quick-freezers usually require relatively large-scale refrigeration equipment. The cooling capacity of the equipment is directly proportional to the amount of quick-freezing of food and inversely proportional to the time of quick-freezing. The quick-freezer is to quickly pass the food through its large ice crystal formation area, and it freezes quickly when the center temperature reaches -18°C.

Food will undergo various changes during freezing, such as physical changes (volume, thermal conductivity, specific heat, dry consumption, etc.), chemical changes (protein denaturation, color change, etc.), cell tissue changes, and biological and microbial changes Wait. The characteristic of fast freezing food is to keep the original nutritional value, color and fragrance of the food to a large extent, that is to say, the cabinet type quick freezer guarantees the great reversibility of the above-mentioned changes in the food during the freezing process. The quick-frozen food has the following advantages:

　　 1. Avoid the formation of large ice crystals between cells;

　　2. Reduce the exudation of moisture in the cells, and less juice loss when thawing;

　　3. The time for condensed solutes, food tissues, colloids and various components in cell tissues to contact each other is significantly shortened, and the harm of concentration is reduced to a low level;

　　4. Rapidly reduce the food to below the temperature of microbial growth activity, which favorably resists the growth of microbes and their biochemical reactions;

　　5. The food stays in the cold storage for a short time, which is beneficial to improve the utilization rate and continuous production efficiency of refrigeration equipment.
