tunnel quick freezerit is an equipment used for food processing and freezing. it can quickly freeze food from normal temperature to the required low temperature. the equipment usually consists of a long, narrow tunnel through which food is gradually passed through on a conveyor belt.

the working principle of the tunnel freezer is to utilize a forced convection air circulation system. when the food passes through the tunnel on the conveyor belt, the cold air generated by the cooler is sprayed into the tunnel, and the air is circulated through the action of the fan to maintain uniform temperature distribution. in this way, the temperature on the surface and inside of the food can be quickly reduced to achieve a rapid freezing effect.

tunnel quick freezerit has the following advantages:

quick freezing: compared with traditional freezing methods, tunnel freezers can freeze food to the required temperature faster, thereby effectively retaining the quality and nutritional value of the food.

uniform cooling: through the forced convection air circulation system, the tunnel freezer can ensure uniform temperature distribution on the surface and interior of the food, avoiding the problems of freezing or uneven temperature during the freezing process.

high production efficiency:tunnel quick freezerusually an automated control system is used to achieve continuous production and efficient operation and improve production efficiency.

save energy:tunnel quick freezerusing a closed-loop circulation system, the cold air generated by the cooler can be recovered and reused to reduce energy consumption.

tunnel quick freezers are widely used in the food processing industry, especially for foods that need to be frozen quickly, such as meat products, seafood, fruits and vegetables, etc. it can not only extend the shelf life of food, but also maintain the taste and quality of food, meeting people's needs for safe, convenient and high-quality food.

it has been widely used by many domestic food manufacturers, providing a new generation of quick freezing machines for individual food quick freezing.

quick freezer refrigeration principle

low temperature refrigeration is carried out in a closed refrigeration system. the compressor sucks the low-pressure gas refrigerant in the evaporator from the low-pressure end, and compresses it into high-temperature and high-pressure gas and sends it to the condenser. by dissipating heat, it is condensed into high-pressure liquid.

it flows through the drying filter to remove water and impurities, and then throttles the liquid into the evaporator through the capillary tube. at this time, due to the sudden drop in pressure, the liquid boils and evaporates rapidly and absorbs heat, causing the temperature inside the box to drop.

the evaporated low-pressure gas refrigerant is then sucked back into the compressor, and the cycle repeats itself. the refrigerant has been charged before leaving the factory. under normal circumstances, the refrigerant does not need to be replaced or added.
