GZLS Freeze Vacuum Drying Machine (Vacuum freeze dryer ) (lyophilizer )( Freeze drying machine)

Preface

The vacuum freeze dryer is an advanced method for the material dewatering.It freezes the moisture materail 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 as that before drying. Therefore, as its large contact area, the processed material can be recovered quickly after being watered, and it can be stored for a long period in a sealed vessel.

3. Electric control unit has advanced measure system which can guarantee the quality of products.
4. The material of drying box, condensator, evaporator, vacuum tube is stainless steel according to the requirement of GMP.
5. The refrigeration system is unipolar or bipolar which can rach the perfect low temperature and can be conveniently operated and repaired.
6. The vacuum system is bipolar which can keep products in the best vacuum condition in order to have the drying process in a shorter term.
