Vacuum freeze dry equipment

The functioning principle of the vacuum freeze dry equipment: to start with, freeze the raw product listed below the eutectic factor temperature level to make the water in the items into solid ice, and after that pack the pre-treated items right into drying chamber of the vacuum freeze dry equipment under reduced temperature level vacuum state.

The vacuum freeze dry equipment is mainly composed of vacuum freeze-drying chamber, vacuum system, refrigeration system, heating unit and also control system. The fundamental technological procedure adopted by vacuum freeze dry equipment is: pretreating → cold → vacuum drying → product packaging → finished item.

The warmth energy of items is supplied by the heating plate via heat transmission or radiation, to ensure that the water in the product is directly sublimated from ice to vapor status. The continually sublimated vapor is condensed and caught to the U-shaped coil up until the heating as well as vacuumizing are quit according to the freeze-drying curve to fulfill the specific requirements. After 15 ~ 24 hours, the products are dried, and the water is relocated to vapor condenser of the vacuum freeze dry equipment.
