Vacuum freeze dry equipment

The vacuum freeze dry equipment is generally made up of vacuum freeze-drying chamber, vacuum system, refrigeration system, heater as well as control system. The basic technical process adopted by vacuum freeze dry equipment is: pretreating → freezing → vacuum drying → packaging → ended up item.

The warmth power of items is supplied by the heating plate through warmth transmission or radiation, so that the water in the item is straight sublimated from ice to vapor standing. The constantly sublimated vapor is condensed and also captured to the U-shaped coil up until the heating and vacuumizing are stopped according to the freeze-drying curve to satisfy the specific demands. After 15 ~ 24 hours, the materials are dried, as well as the water is relocated to vapor condenser of the vacuum freeze dry equipment.

The working concept of the vacuum freeze dry equipment: first of all, freeze the raw product listed below the eutectic factor temperature 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 vacuum state.
