Advantages of freeze-drying:

Freeze drying has the following outstanding advantages compared with common drying, boiling drying, spray drying and vacuum drying.

a. Freeze drying is the process of drying at low temperatures, which does not cause protein denaturation but can cause microorganisms and other organisms to lose their biological vitality. This is particularly suitable for the dry storage of biologically active products, biochemical products, genetic engineering products, and blood products with poor thermal stability.

c. During the low-temperature drying process, the growth of microorganisms and the action of enzymes are almost impossible, thus maintaining the original properties of the substance relatively well.

d. After drying, the volume and shape remain basically unchanged, and the substance is sponge like without drying shrinkage. When rehydrated, it has a large contact surface with water and can quickly return to its original shape.

e. Because it is usually dried under vacuum, there is very little oxygen gas, which protects easily oxidizable substances.

f. It can remove 95% to 99.5% of the moisture in the substance, and the product has a long shelf life.
