Technical advantages of liquid nitrogen quick freezer

As the sales of quick-frozen food in the market continue to rise and industry leaders continue to introduce their own new products and excellent products, quick-frozen food has received widespread attention from many people for a while. Nutritionists even claim that quick-frozen food is a kind of food with extraordinary nutrition and taste. This is a single stone that has stirred up waves and has become the object of attention of many white-collar workers and young people.

Professor Meng Suhe, chairman of the Chinese Society of Food Science and Technology, said: “Frozen food contains some cuisines that often appear on our table, such as pork, onions, tomatoes, and celery. As long as the technology is good, the nutrients can be completely retained. "As soon as this statement came out, it attracted the attention of many consumers and triggered a hobby of consumption habits.

 Normally consumers are used to buying ingredients for a few days or a week at a time and putting them in the refrigerator, of course white-collar workers and office workers. This consumption habit is disapproved at all. The storage in the refrigerator at home is totally different from the quick freezing. The quick freezing preserves nutrients to a large extent, while the slow freezing at home is actually killing the nutrients. This is why Nutritionists advise white-collar workers not to store so many ingredients but the real reason to buy fresh ingredients every day.

The food quick-freezer is based on the extremely low temperature of -196C° of liquid nitrogen, and freezes the food for 5 minutes. This rapid cooling passes the ice crystal formation zone (-10C~-50C) to prevent large ice crystals from in the food cells The formation destroys the cell wall, greatly maintaining the original flavor and quality of the product. The excellent dumplings produced by food manufacturers use minus 35 degrees quick-freezing technology to freeze the cells in an instant to avoid the loss of nutrients and ensure the taste and quality of the food.

In addition to ensuring the quality of the food, Dahua retains the nutrients of the food, and more importantly, the quick-freezing equipment is pollution-free, environmentally friendly and energy-saving. Liquid Nitrogen Liquid nitrogen is non-toxic and inert to food ingredients. So far, it is a very environmentally friendly and economical freezing and cooling medium in the world. Moreover, the liquid nitrogen quick-freezing equipment consumes less power. The device relies on liquid nitrogen phase change refrigeration and the transformation of internal energy to achieve the purpose of quick freezing and preservation. From the principle of refrigeration, it does not need to directly consume electrical energy.

The operation is also very simple, and it can be easily connected to the existing production line, the structure is relatively simple, the system works under pressure, there are few failures, and no high-pressure equipment. Not only that, the liquid nitrogen quick-freezing equipment also occupies a small space in the plant, the one-time investment is also small, the operating cost is low, the maintenance cost is also low, the dry consumption of materials is small, and the dry consumption loss rate of ordinary equipment is 3 to 6%. Nitrogen quick freezing can be reduced to 0.25～0.5%
