The technological innovation of food processing industry is also developing constantly. The traditional ammonia food quick-freezing machine has been unable to keep up with the pace of food processing industry. This is because the traditional ammonia machine has poor ability to adjust and adapt to temperature changes, and the temperature is often in fluctuation occasions, and its heat transfer temperature difference will be large under the condition of changing temperature, which means that the efficiency will decline. In addition, the increase of heat transfer temperature difference means the increase of dry consumption, which will directly lead to the decline of food quality and the loss of goods quality. In addition, the selection of ammonia machine requires a lot of on-site installation work, and the ammonia machine occupies a larger factory area. Ten advantages of liquid nitrogen quick freezing machine;

Liquid nitrogen is by far the most environmentally friendly and economical freezing and cooling medium in the world. ?

With the least investment, we can create a number of high-quality freezing and cooling production lines.

Fast freezing in 5 minutes greatly shortens the time to market and does not need to store a large number of products.

Reduce water loss, no loss, no weight loss, maintain original freshness, improve product quality, and improve output rate (more products can be operated at the same time). ?

Save factory space, and it is easier to be connected to the existing production line. ?

Minimum installation cost. ?

Low maintenance cost. ?

Save cleaning time. ?

The shelf life is longer, which is 1~3 times that of traditional quick freezing. ?

Completely solve the problems of overproduction, expiration and deterioration.
