Freeze drying is a technology that uses the principle of sublimation to dry. It is a process that rapidly freezes the dried substance at low temperature, and then sublimates the frozen water molecules into water vapor in an appropriate vacuum environment. The products obtained by vacuum freeze-drying are called lyophilized products, and this process is called freeze-drying. The drug is always in a low temperature (frozen state) before drying, and ice crystals are evenly distributed in the drug. The sublimation process will not occur concentration due to dehydration, avoiding the side effects such as foam and oxidation caused by water vapor. The dried medicine is in the form of dry sponge and porous, and its volume is basically unchanged. It is very soluble in water and can be restored to its original state. To prevent the physical, chemical and biological denaturation of dry drugs.
The application advantages of freeze-drying machine in the biological field can prevent the degeneration and decomposition of biological products and drugs under the action of water and heat, cause less damage to biological tissues and cell bodies, and reduce the death of live bacteria and viruses. Low temperature drying, the loss of volatile components in the material is very small, the growth of microorganisms and the role of enzymes cannot be carried out, and the original properties can be maintained. As the drying is carried out under vacuum, there is less oxygen, so the substances that are easy to oxidize are protected. Drying can remove more than 95%~99% moisture, so that the dried products can be stored for a long time without deterioration. For example, human plasma can be stored in liquid state for only a few months, while it can be stored for 5-10 years after freeze-drying. For example, the effective period of live measles attenuated vaccine in liquid state is three months, and it can be extended for one year after freeze-drying. The disadvantages of vacuum freeze-drying are large investment, high maintenance cost and high product cost.
