Freeze-drying is a technique for drying by the principle of sublimation, which is to quickly freeze the dried material at low temperature. Then the frozen water molecules are directly sublimated into a process of water vapor evolution in a proper vacuum environment. The product of this process is called Freeze-dried product.

Product Features

1.Dry chamber door and cold well door adopt aviation acrylic materials with high strength and no leakage.
