What are the advantages of lyophilizers in the biological field?

A lyophilizer is an effective new type of drying device used to dry heat sensitive substances and substances that need to maintain biological activity. At present, many domestic pharmaceutical companies use freeze-drying methods to process drugs, such as various antibiotics, biological extracts, vaccines, enzyme products, etc., as well as in the beauty field, such as cosmetic freeze-dried powder, freeze-dried mask and so on.

The lyophilizer has advantages in the biological field, and it can prevent the biological products and drugs from being easily deformed and decomposed under the action of water and heat to a large extent, and has less damage to biological tissues and cell bodies, and can reduce live bacteria. Body and virus death. Low temperature drying, the loss of volatile components in the material is small, the growth of microorganisms and the action of enzymes cannot be carried out, and the original traits can be maintained. Since the drying is carried out under vacuum, the oxygen is less, so that the easily oxidizable substance is protected. Drying can eliminate 95%~99% of water, so that the dried product can be preserved for a long time without deterioration. For example, human plasma can only be stored for a few months in a liquid state, and can be stored for 5 to 10 years after lyophilization. For example, a live attenuated measles vaccine is valid for three months in liquid form and can be extended for one year after lyophilization. The disadvantage of vacuum freeze drying is that the investment is large, the maintenance cost is high, and the product cost is high.
