The tunnel type quick freezer utilizes the quick return characteristic of a four link mechanism to achieve material transportation. It is suitable for single quick freezing of granular, flaky, segmental and blocky materials such as melon slices, onions, potato chips, peas, potato blocks, Snow pea, spinach segments, grapes, apricots, dates, etc. Small size, flexible operation, high output, non sticking, non caking, no printing marks, and no ice sliding of materials.

Equipment principle:

Two conveyor belts are used to transport food. The characteristic of this structure is to divide the food into two sections for freezing, with the section being the surface freezing zone and the second section being the deep freezing zone; After the granular food enters the freezing chamber, it is quickly cooled in the first row, that is, the surface layer is cooled to the freezing point temperature. However, it enters the second section and undergoes deep freezing in an ideal fluidized bed.

The equipment adopts the principle of fluidization quick freezing, Freon refrigerant and tunnel quick freezing machine. Generally, it is customized according to the product characteristics and output. It is widely used:

1. It can be used to quickly freeze seafood, such as crayfish, scallops, fish, etc;

2. It can be used for frozen meat products, such as chicken products, chicken fillets, meat skewers, pork, beef, and mutton, etc;

3. It can be used to freeze fruits and vegetables, such as frozen corn, frozen beans, frozen soybeans, and so on.
