Introduction： Vacuum freeze drying technology, also known as sublimation drying, is a method to pre-freeze water-containing material and sublimate its moisture under vacuum. The original biological and chemical properties of freeze-dried items are basically unchanged, which is easy to keep for a long time. After adding water, they can be restored to the state before freeze-drying and maintain their original biochemical properties. Therefore, vacuum freeze drying technology is widely used in food, chemical, biological products and other fields.

Introduce Vacuum freeze drying refers to the process of removing water or other solvents from frozen samples. During the whole drying process, sublimation prevents the sample from passing through the liquid state, and the sample is in a vacuum state, and the temperature is generally lower than -10°C. The purpose of vacuum freeze-drying is to restore the original characteristics of the sample after rehydration. Because the drying process is carried out at low temperatures, it can be used for some materials that are easily denatured at high temperatures, such as proteins, and can ensure that the properties of other compounds will not change. After vacuum freeze-drying, most biological products such as tissues, tissue extracts, bacteria, vaccines and serum will become dry samples, and no e.
