呼和浩特Impact tunnel freezing machine

The impact tunnel freezer is a new type of high efficiency clean tunnel freezer. It is suitable for fast freezing of granular, small lumps flat foods, such as shrimp products, fish fillets, hamburger patties other flake foods.

Compared with the traditional tunnel freezer, its advantages are:

1. Freeze quickly without producing large ice crystals, keep the quality of the food as much as possible, as fresh as ever after thawing.

2. The surface of the food quickly hardens crusts, locks the internal moisture, minimizes the drying consumption of frozen products.

3. The freezing time is extremely short the work efficiency is high (fluidized quick-freezer wholesale).

4. The quick-freezer with the same capacity has a small footprint.

The evaporator of the impact tunnel quick-freezing machine is placed on both sides of the conveyor belt, the centrifugal fan with large air volume is placed directly above the conveyor belt. A high-pressure air chamber is formed under the air outlet of the fan. The strong cold air of this high-pressure air chamber is immediately drawn the evaporation fins by the centrifugal fan, the temperature is below -40°C. One wind direction is directly blown to the frozen products on the conveyor belt through the gap between the air deflectors below. The frozen products placed on the conveyor belt have the same effect as an air knife in the width direction (locally extremely high wind speeds low wind speeds nearby); the other wind direction is set on both sides of the conveyor belt between the two conveyor belts. The air duct is forced to the bottom of the conveyor belt through the air guide hole above the air duct. In this way, the frozen products on the conveyor belt can be cooled frozen extremely quickly.

The structure of the impact tunnel freezer is more reasonable than the traditional tunnel freezer: (price of the fluidized freezer)

1. The cold air high-pressure zone is located in the center of the quick-freezer, there is a buffer zone in the inlet outlet sections of the heat preservation enclosure. At the same time, the high-pressure zone, the buffer zone the inlet outlet sections are equipped with wind shields to prevent Run cold.

2. There is a straight passage with a width of 500mm a height of 1600mm under the evaporator. The opening of the air passage is equipped with a cleaning door that is easy to disassemble. There is a sliding maintenance door between the evaporators, which can easily enter the space above the second floor platform. Water frost, internal cleaning of tunnel machine maintenance of centrifugal fan.
