Product Detail


Vacuum freeze dryer is suitable for drying product such as food, drug products, biological products, Chinese medicine and more. It is to dry product at low temperature to preserve, stabilize, store and increase the life of products.. Freeze vacuum drying is a new type of box structure introduced by the vacuum freeze dryer that combines the refrigeration system, vacuum system, heat transfer oil heating system, and moisture removal system. It uses the space for storing materials in the box to dry.
