There are four types of liquid nitrogen quick freezing machines: quick freezing type, spiral type, box type, and immersion type; The liquid nitrogen quick freezing machine utilizes the low cooling capacity of liquid nitrogen -196 ℃ to quickly remove the heat from food, freeze quickly, lock in the moisture of frozen products, reduce water loss, and ensure the freshness and appearance of food. This is something that traditional compressor refrigeration does not have. With the development of the economy and the improvement of people's living standards, liquid nitrogen quick freezing machines will be more widely used for quick freezing and preservation in the food industry and marine fisheries.

Introduction and characteristics of quick freezing liquid nitrogen freezer:

1. Adopting a simple and easy to clean design concept, there is no need to shut down for defrosting, and continuous production can improve production efficiency;

2. The working temperature of the liquid nitrogen freezer can be set arbitrarily between -30 ° C and -120 ° C, and it can freeze various seafood, meat, fish and whole fish, fruits and vegetables, buns, instant fast food, baked goods, and more.

3. The operating system adopts a touch screen control panel with a one click start mode, which is simple and easy to learn. All operating data is clear at a glance, and the operating speed and freezing temperature can be adjusted at any time, monitoring the temperature changes inside the quick freezing in real time;

4. The internal cooling circulation and exhaust system of quick freezing is composed of a motor and a low-temperature fan (technology). The low-temperature fan inside the quick freezing does not need to be stopped for defrosting and can operate continuously without being frozen, while ensuring that the food is quickly and evenly frozen and the refrigerant is efficiently utilized;

5. The amount of liquid nitrogen required for quick freezing is automatically adjusted according to the set temperature to minimize the use of liquid nitrogen while ensuring uniform temperature inside the quick freezing process;

6. The top cover of the quick freezing machine can be vertically raised and lowered, making it easy to clean the frozen interior and ensure the hygiene of the frozen food;

7. The quick freezing machine adopts a segmented design, which makes on-site lifting and assembly quick and convenient.
