Freeze drying is a technique that utilizes the principle of sublimation for drying. It involves rapidly freezing the material to be dried at low temperatures, and then in an appropriate vacuum environment, the frozen water molecules are directly sublimated into water vapor and released. The substance is always at a low temperature (frozen state) before drying, and ice crystals are evenly distributed in the substance. During the sublimation process, concentration will not occur due to dehydration, and side effects such as foam and oxidation caused by water vapor are avoided. Freeze dried products have a sponge like appearance, no drying shrinkage, good rehydration properties, and low moisture content. After packaging, they can be stored and transported at room temperature for a long time.
