Working principle of vacuum freeze dryer

Instead of traditional vaporization dehydration method, the vacuum freeze drying technology is dehydrate products by sublimation directly from ice to vapor. During the Freeze drying process, the materials will be frozen to -18°c, then move into the vacuum drying tank for dehydration, automatic control system will set the vacuum and heating temperature according to the freeze drying cirve of each products to maintain the proper circumstances for FD processing. The materials stay in frozen status during the drying process and water vapor will be condensed on the surface of cold trap coils to absort the water out from the materials.

Application 

The vacuum freezing and drying machine can be widely used in various fields, such as vegetables, fruits, condiments, seafood, biological products, medicine, beverage, specimen, etc.
