Pemasok yang Diaudit Freeze-drying (hereinafter referred to as lyophilization) is a method in which an aqueous substance is first frozen into a solid state, and then the water therein is sublimated from a solid state into a gaseous state to remove water and preserve the substance.
In the field of biotechnology products, freeze-drying technology is mainly used for the production of drugs such as serum, plasma, vaccines, enzymes, antibiotics, hormones; biochemical inspection drugs, immunology and bacteriology; drugs; blood, bacteria, arteries, bones Long-term preservation of skin, cornea, nerve tissue and various organs.
Application of Freeze Drying Machine:
Characteristics
* Many heat sensitive substances do not degenerate or inactivate.
* When drying at low temperatures, some of the volatile components in the material are lost.
* During the lyophilization process, the growth of microorganisms and the action of enzymes cannot be carried out, so that the original traits can be maintained.
* Since it is dried in a frozen state, the volume is almost constant, and the original structure is maintained, and concentration does not occur.
* The dried material is porous and spongy. After adding water, it dissolves quickly and completely, and almost immediately restores its original character.
* Since drying is carried out under vacuum, there is very little oxygen, so some easily oxidizable substances are protected.
* Drying can remove 95%~99% of water, so that the products can be preserved for a long time without deterioration.
