Cryogenic liquid nitrogen freezer

 Liquid nitrogen deep-temperature freezing and quick-freezing machine is a series of quick-freezing equipment recently developed by our company. According to different frozen products, including continuous and intermittent two series, different specifications. Liquid nitrogen quick freezing can be used in various fields. With the development of the liquid nitrogen industry, prices have fallen. Currently, it is gradually being used in meat, freshwater fish, crayfish, seafood, fast food, instant food, pasta, fruits, milk Products and baking products are widely used.

>> LND Series Ultra-low Temperature Liquid Nitrogen Quick Freezer Features:

    1. Instant rapid temperature reduction: Compared with traditional air-cooled and quick-freezing equipment, the cooling rate of liquid nitrogen instantaneous vaporization can be increased by 5-10 times, and it can quickly pass through the food ice crystal point (0 ～ -5 ℃). The small ice crystals are not easy to damage the cell wall. Reduce juice loss and maintain good flavor and quality of food.

    2. Solve the air-cooled and quick-freezing long-term ice crystal generation area, greatly improving production efficiency

    3． Nitrogen is taken from the air and is attributed to the air, without worrying about the toxicity of ammonia and the destruction of the ozone layer by Freon.

    4． The food has low dry consumption and excellent quality: there is no air blowing on the surface of the food, and the heat can be transferred by heat to ensure that the product has the same quality on the surface, high yield, and good appearance.

    5． Small footprint.

    6. No hygienic dead corner, easy to clean.

    7. The diversion wind machine will automatically adjust the diversion speed according to the temperature in the warehouse to ensure that the discharge port does not run nitrogen.
