The vacuum freeze drying machine is an advanced method for the material for the material de-watering. 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 nutritious contents in the material, which are easy to be denatured in a warm condition, will be lost a little. When the material is freezing dried, it will be formed into a porous one and its volume be basically the same to that before drying. Therefore, the processed material can be recovered quickly if being watered again, because of its large contacting area and it can be stored for a long period in a sealed vessel.

Basic Parameter of the 10m² Vacuum Freeze Dryer

Main Feature 

1. All the parts contacting the products are made of  SUS 304L stainless steel, the surface roughness reaches Ra≤ 0.5 um

2. The inner circle of the chest has a smooth transition without dead corner, no objects accumulated.

3. Consider for user, the structure is easy to clean.

4. Automatic control system.Advanced intelligent control system keeps the system runningstably and reliably in a long time. Furthermore, simple opera-tion can be much easier to handle.
