Tunnel-type compressor quick-freezing machine is a more commonly used traditional one. Generally, the theoretical temperature can reach minus 35 degrees, and the freezing time is generally about half an hour. The machine itself is relatively expensive. The later operating cost is mainly the compressor's electricity cost, and the later maintenance is compared. Trouble, no preservation effect.
The tunnel-type liquid nitrogen quick-freezing machine is a relatively new quick-freezing method that has emerged in China in recent years. It has been used more abroad before. This technology has gradually matured and developed in China in recent years. The requirements are getting higher and higher, and there will be more and more companies using liquid nitrogen quick freezers in the later period. The cost of the machine itself is much lower than that of the compressor. The later operating costs are mainly the cost of liquid nitrogen consumption, because the liquid nitrogen quick freezers are constantly freezing food. For liquid nitrogen, the theoretical consumption is that it takes 10-15 minutes to freeze one ton of food, and consumes about 0.7 tons of liquid nitrogen.
Speaking of this, it is inevitable to mention liquid nitrogen. Liquid nitrogen has a fresh-keeping effect, so many companies are beginning to pay attention to liquid nitrogen quick freezing, but many food manufacturers do not know that liquid nitrogen needs a large amount of regular consumption when purchasing, so if they plan to use liquid nitrogen For nitrogen quick-freezers, it is recommended to check the price of local liquid nitrogen first. The ex-factory price of liquid nitrogen itself is not high, and it is expensive in freight.
