Vacuum freeze drying technology is the most advanced technology for food dehydration processing at present. Compared with the common drying method, the freeze-dried food produced with this technology features long period of quality assurance, good re-hydration nature, good-looking color, good flavor, taste, shape and high content of nutritious components. The dried food basically remains unchanged in its volume and shape, it looks like sponge and has no shrinking. This kind drying technology can be widely used in process of vegetables, fruits, condiments, aquatic products, biological products, medicine, beverage and etc.
1. At least 1500kg/batch high capacity 2. Continuous running without trouble 3. Low energy consumption 4. Complete automatic.

1. Efficiency of Heating plates
The material of heating plates are aviation aluminum with anodized on the surface, over 100% heat release to the product by radiation way, keep good heating uniformity everywhere.
2. Alternate Vapor trap
Double vapor trap located under the heating plates inside drying chamber, Just trap 1 condensates water vapor until it can't catch vapor any more, then trap 2 starts condensation function, and trap 1 will begin to be defrost ice for another condensation cycle.
3. Continous De-icing
When the trap 2 begins to catch water vapor, the trap 1 begins to be defrost ice on the tube bundle during product drying, after de-icing, the empty and smooth tubes for another condensation cycle.
4. Automatic control system
Advanced intelligent control system keeps whole system stable and reliable running for a long term, furthermore, Simple operation method can be much easier to master.
