Freeze drying is a drying technology that uses the principle of sublimation. It freeze the dried material quickly at low temperature, and then in a proper vacuum environment, the frozen water molecules are directly sublimated into water vapor and overflow. The substance is always at a low temperature (frozen state) before drying, and the ice crystals are evenly distributed in the substance. During the sublimation process, concentration will not occur due to dehydration, thus avoiding side effects such as foaming and oxidation caused by water vapor. Freeze-dried products are spongy, have no shrinkage, good rehydration properties, and low water content. It can be stored and transported for a long time at room temperature after being packaged accordingly.
Freeze dryer is suitable for freeze drying, strain preservation, etc. in biological research, medicine and pharmaceuticals, chemical industry, food processing, colleges and universities, etc.
Freeze drying can protect the activity of heat-sensitive substances, preserve the nutritional value to prevent oxidation, have no additives, and maintain their freshness for an extended period of time. The dried substance is loose and porous, sponge-like. It dissolves quickly and completely after adding water, and almost immediately restoring its original shape.
