Mesh Belt Tunnel Quick Freezer For Fish Seafood Lobster Deep Freezer
Product description
The conveyor belt moves the product along the tunnel. Controlled injection of low temperature liquefied gas can evaporate instantly and reduce the temperature in the tunnel. In the tunnel freezer, the resulting cold gas is rotated around the product surface by a circulating fan. The gas is pumped out after cooling. The temperature dropped rapidly to well below zero. Even the slightest moisture is enough to saturate the atmosphere. These products do not lose moisture and retain their weight.

1. What are the advantages of liquid nitrogen quick freezing compared with the traditional freezers and iqf freezer?
DJL reply: Before answering this question, it is necessary for us to clarify the standard definition of quick freezing: quick freezing of food is to place the pre-processed food into a low-temperature device, pass through the largest ice crystal formation zone within 30 minutes, and the central temperature drops from 0℃ to Below -5℃, the diameter of the ice crystals formed is less than 100μm, and the center temperature of the food after quick freezing must reach the food freezing technology below -18℃. Due to its fast speed, the cell integrity of liquid nitrogen quick-frozen food was much higher than that of traditional freezing method, and the cell damage rate was nearly 80% less than that of slow-freezing food, so its taste, nutrition and color are much better than slow freezing food, In terms of seafood, DJL liquid nitrogen quick-freezing technology can be comparable to seafood in fresh state after freezing and thawing. Therefore, liquid nitrogen quick-freezing technology can better maintain the color, aroma, flavor and taste of food, and its sales value will also be greatly improved.
2. How long can the liquid nitrogen freezer be used?
DJL reply: Due to different refrigeration methods and structural design, its service life can be up to 20 years, about twice as long as the traditional equipment.
