Vacuum freeze dry equipment

The vacuum freeze dry equipment is primarily made up of vacuum freeze-drying chamber, vacuum system, refrigeration system, heating system and control system. The standard technological procedure adopted by vacuum freeze dry equipment is: pretreating → freezing → vacuum drying → product packaging → completed product.

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

The heat of products is supplied by the heating plate with warmth transmission or radiation, to make sure that the water in the item is straight sublimated from ice to vapor status. The continuously sublimated vapor is compressed and recorded to the U-shaped coil until the heating and vacuumizing are stopped according to the freeze-drying curve to satisfy the specified demands. After 15 ~ 24 hrs, the materials are dried, and the water is moved to vapor condenser of the vacuum freeze dry equipment.
