Liquid nitrogen tunnel quick-freezing machine
Liquid nitrogen tunnel quick-freezing machine is a kind of large-scale quick-freezing machine suitable for large output processing and production in factory lines. It has strong quick-freezing capacity, simple operation and high degree of automation. The liquid nitrogen quick-freezing machine adopts new heating technology, temperature control technology and liquid nitrogen dispersion technology, so that the process of program-controlled heating, constant temperature and cooling is uniform and stable. Liquid nitrogen is used as refrigerant to meet the requirements of cooling and environmental protection. Sudong equipment has a variety of specifications, and can be designed and manufactured according to user requirements. The low temperature of liquid nitrogen can reach -196 degrees. When it comes into contact with food, it vaporizes and takes away heat faster. Ultra-low temperature and high heat exchange rate enable rapid freezing. Such rapid freezing makes the resulting ice crystals small and helps maintain the texture of the food, which prevents the loss of water, almost no loss, and maintains the primary color, original flavor and original quality of the food. The refrigerant nitrogen after gasification is uniformly controlled to the front end of the refrigerator, achieving heat reverse exchange, thereby improving the utilization rate of nitrogen. The equipment uses...
