small capacity Vacuum lyophilizer freeze dryer machiney for food drying 

 

Vacuum freeze dryer is a kind of technical method which freezes the moisture in advance and sublimates the moisture in vacuum state. The freeze-dried products are easy to be preserved for a long time. After adding water, they can return to the state before freeze-drying and keep the original biochemical characteristics. For heat sensitive substances such as antibiotics, vaccines, blood products, enzyme hormones and other biological products, freeze-drying technology has many obvious advantages.

 

OR-HFD series small freeze dryer simplifies the tedious operation of small freeze-drying machine, prevents material pollution and accelerates material moisture sublimation. This series of machines have the functions of heating and temperature control, and can view the freeze-drying curve, which is convenient for users to observe the freeze-drying process of materials
