Tunnel type liquid nitrogen quick freezing machine for aquatic products

  At present, with the continuous improvement of people's living standards, the requirements for the quality of fish products are becoming higher and higher
As the storage method of fish products, freezing processing is the main method, but the so-called frozen products are not simply put the fish products into the cold storage for freezing and storage, but processed through the production process of ultra-low temperature frozen liquid
In use & mdash; When freezing food in a general freezer, the water in the food will expand and destroy the cell membrane when it freezes due to the long time required
However, the fish liquid nitrogen quick freezer developed and produced by keweigani can freeze aquatic products at ultra-low temperature and high speed through liquid nitrogen refrigerant of - 196 ℃
This high-speed freezing protects the cell membrane and various tissues in aquatic products from being damaged, water molecules will not expand, let alone lead to the rupture of cell wall
Moreover, it is evenly arranged, which effectively inhibits the growth of microorganisms in aquatic products and makes the food taste the same after thawing and before freezing, Fresh and delicious
Compared with other ordinary aquatic products quick freezing equipment, the small fish liquid nitrogen quick freezing machine developed and produced by keweigani has incomparable advantages

 
1
When liquid nitrogen comes into contact with frozen food, make the frozen goods pass through the largest ice crystal formation area in a very short time under the ultra-low temperature state of - 35 ℃ ~ - 85 ℃
 
2
Make the pressure inside and outside the food cells reach a relative balance, protect the cell tissue of the frozen goods to the greatest extent, maintain the cell activity, ensure the fresh quality of the frozen goods, and retain the original nutrients to the greatest extent
Reduce the exolysis of water in cells and reduce the loss of juice during thawing

 
3
The contact time between concentrated solute and food tissue, colloid and various components in cell tissue is significantly shortened, and the harm of concentration is reduced to the lowest level

 
  4
Rapidly reduce the food to the temperature of microbial growth activity, which is beneficial to resist the growth of microorganisms and their biochemical reactions
Due to the use of ultra-low temperature freezing technology, it can completely and effectively kill viruses and sterilize products during quick freezing
After quick freezing, the product can be directly refrigerated in the cold storage, and there is no need to worry about the bacterial reproduction attached to the food and damaging the food

 
5

After thawing, nutrients will not be lost, and the original flavor, taste and nutritional value of the food will be maintained, even better than fresh food in taste
 
6

Generally, conventional freezing takes more than 4 hours or even more than 10 hours, while quick freezing technology takes only a few minutes to more than 10 minutes

 
7

Liquid nitrogen quick freezing technology has impeccable advantages in crustacean, whole fish, shellfish, tuna, yellow croaker, lobster, other seafood and aquatic products, as well as single freezing of beef and mutton
Vacuum packaged sashimi and shrimp are also the advantages of liquid freezing technology, which is highly competitive in quality

 
Food stays in the freezing equipment for a short time, which is conducive to improving the utilization rate and continuous production of the equipment
Most foods begin to freeze when the temperature drops to - 1 ℃, and most ice crystals are formed between - 1 ℃ and - 5 ℃
This stage is called the highest ice crystallization stage
Liquid quick freezing can greatly shorten the freezing time at this stage and eliminate this part of heat as quickly as possible, which is of great significance to improve the quality of quick-frozen food

 
Keweijiani is the largest and largest professional manufacturer of liquid nitrogen quick freezing equipment in China
The products use the latest heating technology, temperature control technology and liquid nitrogen dispersion technology to make the process of programmed heating, constant temperature and cooling uniform and stable
In addition to the simple and stable operation of the unit, the unit is energy-saving and environment-friendly
It can meet the demand of 24-hour continuous production
