Sea Food Liquid Nitrogen Freezing Tank

Seafood liquid nitrogen cryopreservation technology isa new food freezing technology in recent years. Standard temperature of liquid nitrogen is -195.8 and it is currently recognized as the most environmentally friendly, efficient and most economical cooling medium. When liquid nitrogen and seafood contacting, temperature difference is over 200 and the food could be rapidly frozen within five minutes. Rapid freezing makes ice crystals of seafood very small, eliminating the loss of moisture, inhibiting the destruction of bacteria and other microorganisms. The food would not meet any oxidation, discoloration and rancidity, so to keep the color, flavor and original nutrients; and long term cryopreservation can also maintain the best taste.

Overview:

Seafood being frozen in liquid nitrogen tank has advantages of rapidly frozen, long term preservation, low equipment investment costs, low operating costs, no energy costs, no noise and almost no maintenance costs etc. So it is firstly used in the upscale seafood freezing application. It is foreseeable that liquid nitrogen cryogenic freezing technology will gradually replace traditional mechanical refrigeration technology, and it will cause the revolution of products freezing area. Liquid nitrogen cryopreservation of seafood is a new food freezing technology in recent years. The standard tempera-true of liquid nitrogen is – 195.8°C, which is the most environmentally friendly, efficient and economical cooling medium recognized by the food science and technology circles. When liquid nitrogen is in contact with seafood, the difference of temperature is more than 200°C, and the rapid freezing of food can be realized within 5 minutes. Rapid freezing makes the ice crystal parties produced by seafood smallest, prevents the loss of water, inhibits the destruction of food by bacteria and other microorganisms, makes food almost free from oxidative discoloration and fats rancidity, and maintains the original color, flavor and nutrients of seafood, so long-term freezing can also ensure the best taste.

Seafood liquid nitrogen freezer is the first to be used in high-grade seafood freezing because of its fest refrigeration, long storage time, low equipment input cost, low operation cost, no energy consumption, no noise and no maintenance. It can be predicted that liquid nitrogen cryogenic refrigeration technology will gradually replace the traditional mechanical refrigeration and refrigeration technology, which will bring profound changes to the operation of traditional freezer.

Product Features:

1. High vacuum multi-layer insulation technology is adopted to ensure very low toss rate of liquid nitrogen evaporation (<0.8%) and very low operation cost;

2. Intelligent monitoring and management system of liquid nitrogen tank can monitor the temperature and liquid level of seafood tank in real time, realize automatic rehydration, alarm for various potential faults, and ensure the safe operation of equipment At the same time, it provides the storage goods management system, which makes the management of goods out of warehouse and in warehouse clear at a glance;

3. The inner and outer shells are made of food-grade stainless steel to ensure the product’s life for more than 10 years;

4. The internal revolving tray structure is designed to facilitate seafood access. Some models can be equipped with electric rotating structure to realize automatic access;

5. It can be stored in both gas and liquid to ensure that the temperature of the tank mouth reaches – 190°C.
