Vacuum Freeze Dryer

The vacuum freeze drying is an advanced method for the material for the material dewatering. It freezes the moisture material in the low temperature and makes the water inside sublimate directly in the vacuum condition. Then it collects the sublimated vapor by means of the condensing way so as to dewater and dry the material. Being processed by the vacuum freeze drying, the physical, chemical and biological states of the material are basically unchanged. The volatile and
