freezing dryer: Drying area:0.5-200Sqm Capacity:5-2400kg/8-15hrs Drying temp.50-120C, Vacuum freeze dryer.

Working principle,Vacuum freeze dryer

After pretreatments, the raw materials are to be frozen in a cold room. After freezing, raw materials are to be exposed in a vacuum hot drying pot. Inner moisture of the materials is to sublimate from solid state to gaseous state, the condenser installed in the back side capture the gaseous state water, and change it to solid state again.

 

Application, vacuum freeze dryer

Fruit, vegetable, aquatic, meat, instant foodstuff, chemical stoneware ect.
