quick frozen

The spiral quick-freezing machine consists of a flexible conveyor belt, a rotating drum, a fan, and an air curtain. It consists of transmission, variable speed, flushing, safety, refrigeration and other devices. The flexible conveyor belt (chain) constitutes a spiral loop. When the drum rotates, the friction force between the slats and the chain installed on the drum is used to move the chain around the drum. The material is fed in through the entrance and placed On the flexible transmission belt, the revolving drum spirally moves upward from the lower part, while the cold air passes through the refrigerator, fan and conveyor belt to freeze the material. recycle. The material is discharged from the upper part after freezing. In order to prolong the service life of the chain, an overturning mechanism is installed to make the two ends of the chain wear in turn. The air curtain is installed at the material inlet and outlet to reduce the loss of cold capacity. The spiral quick-freezer adopts a compressor refrigeration system, and the cold air temperature is -5～-40℃, which can be adjusted. Under the condition of cold air temperature -35℃ and freezing time of 30min, the processing capacity is 100～500kg/h. The machine is characterized by compact structure, small footprint, continuous operation, rapid freezing, and is suitable for processing thin meat slices, fish slices, ice cream and cold snacks.

The processing method of preserving fruits by low temperature quick freezing. After the fruit is frozen, the internal biochemical process stops. Since most of the water content has been frozen into ice, the microorganisms have no water necessary for life, and the low temperature also hinders the activity and reproduction of the microorganisms, so the fruit can be preserved for a long time.
