2、 Industry Knowledge: Core Science Popularization of Vacuum Freeze Drying Machine

（1） Core working principle

The vacuum freeze dryer works based on the principle of sublimation: first, it rapidly freezes the water containing substance into a solid state, and then in a specific vacuum environment, the solid water molecules are directly sublimated into steam to escape, achieving water removal. This process does not cause material concentration and can largely preserve the original physical and chemical properties and biological activity of the material. After drying, the material appears as a porous sponge with good rehydration properties.
