Factory source Dewar Tank - Sea food freezing tank – Haishengjie

Overview:

Seafood liquid nitrogen cryopreservation technology is a 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 is in contact with seafood, The temperature difference is over 200 ℃, and the food could be rapidly freezed within 5 minutes.Rapid freezing process makes the ice crystals particals of seafood very small, prevents the loss of water, inhibits the destruction of 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 fast 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 regrigeration technology, which will bring profound changes to the operation of traditional freezer. 

Product Features:

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

○ Intelligent monitoring and management system of liquid nitrogen tank can monitor the temperature and liquid level of seafood tank in real time, realize automatic filling, alarm for various potential faults, and ensure the safe opertion 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. 

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

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

○ It can be stored in both gas and liquid to ensure that the temperature of the tank mouth reaches to -190 degree C.

Product advantages:

○Low evaporation rate of liquid nitrogen
High vacuum multilayer insulation technology ensures low evaporation loss rate of liquid nitrogen and low operating cost.

○ New technology keeps original taste
Liquid nitrogen rapid freezing, food ice crystal particles minimum, eliminate the loss of water, inhibit bacteria and other microorganisms damage to food, so that food almost no oxidation discoloration and only rancidity.

○ Intelligent monitoring system
Can be equipped with intelligent monitoring system, real-time network monitoring of each tank temperature, liquid level height, etc., can also realize automatic filling, all kinds of fault alarm.At the same time to provide inventory management system, goods in and out of storage management.
