Zhuoda Yuntong Tunnel style Liquid Nitrogen Freezing Machine

Description :

　　Quick freezing characteristics of Chengdu Zhuoda Yuntong Tunnel:

　　1. Freezing speed is fast. Compared with traditional air forced circulation freezing devices, the heat transfer intensity has increased by about 30-40 times. This is because the thermal resistance during freezing decreases by about 15-18 times, the heat release coefficient between the product surface and the cold air increases by about 4-6 times, and the effective heat transfer area increases by about 3.5-10 times. So the freezing speed is several tens of times faster than that of ordinary freezing devices. Due to its fast freezing speed, it can maintain the original nutritional content and freshness of food to the greatest extent possible.

　　2. Realize rapid freezing of individual units. After freezing, food will not stick together, achieving IQF freezing. Not only is the quality good, but it is also convenient for packaging and consumer consumption.

　　3. Food consumption is low. Each frozen food has a thin layer of ice film on its surface, which is beneficial for maintaining the freshness of the food and preventing oxidation, while also reducing dry consumption. Comparative experiments conducted by Swedish scholars on mushrooms, strawberries, etc. have shown that the dry consumption of liquid nitrogen freezing is almost only about half of that of forced air tunnel freezing. This is particularly important for higher priced foods.

　　4. Easy to achieve mechanization and automation for continuous production, with high production efficiency. Workers can operate at room temperature, improving working conditions.
