Freeze vacuum drying machine

The vacuum dryer is composed of a refrigeration system, a vacuum system, a heating system, and an electrical instrument control system. main department
The components are drying box, water trap (cold trap), refrigeration unit, vacuum pump, heating/cooling device, etc. It works by putting
The articles to be dried are first frozen to below the triple point temperature, and then the solid water (ice) in the articles is allowed to freeze under vacuum conditions.
It is then sublimated into water vapor, which is removed from the article to dry the article. After the materials are pre-treated, they are sent to the quick-freezing warehouse for freezing, and then
It is sent to the drying bin for sublimation and dehydration, and then packed in the post-processing workshop. The vacuum system establishes low pressure conditions for the sublimation drying chamber,
The heating system provides latent heat of sublimation to the material, and the refrigeration system provides the required cooling capacity to the cold trap and drying chamber.

Description

Vacuum Freeze Dryer Laboratory Lyophilizer Pharmaceutical Commercial Food Vegetables Fruit Dryer High Productivity LyophilizationThe 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.
