Today, let's follow Guanfeng Vegetable Processing Machine manufacturer to see the little knowledge of quick freezing machine:

Food freezing speed is proportional to temperature difference. The pursuit of low temperature in quick freezer is for fast crystallization of food, and the set temperature is - 35 degrees. On the one hand, quick freezing is considered, and on the other hand, energy saving is considered. Therefore, the closer the food entry temperature is to the freezing point, the faster the food freezes. The high temperature before crystallization is reserved for that precool section to complete, thereby achieving the purposes of high-quality quick freezing and energy conservation. In addition, the entry temperature is close to freezing point or the key to reduce dry consumption of food. Avoiding the cooling consumption of the quick freezing machine also lies in avoiding the cooling consumption of the splicing gaps of the insulation boards of the enclosure structure.

The insulation board of the enclosure structure of the quick freezing machine adopts polyurethane integral foaming form, and all the joint seams of the storage boards are sealed with double-sided special sealing glue and are filled and foamed twice to prevent the joint seams of the insulation boards from running cold. There are different requirements for air volume and wind speed in various quick freezers, and their energy-saving methods are also different. The tunnel type mesh belt single quick freezer is designed with grid strip-shaped regulating and guiding components on the basis of ensuring the refrigerating air volume, thus greatly improving the surface wind speed of frozen products. At the same time, it also improves the surface area of frozen products and the circulation rate of wind.

In addition, the grid strip-shaped regulating and guiding component of the symmetrical wind direction regulating device can control the cold air to run from the inlet to the outlet. The operation power of the fan motor is reduced, thus reducing the cooling consumption of the fan motor ( reducing the wind pressure and increasing the wind speed ), thus improving the efficiency. In order to reduce the cold consumption of mechanical transmission and conveyor belt, the mechanical transmission and conveyor belt system are kept running at low temperature, and the inlet and outlet are insulated to save the cold consumption by using the cold air lingering in the quick freezing chamber.
