Freeze-drying operation precautions for vacuum freeze dryer
Freeze drying of a vacuum freeze dryer refers to the process of removing moisture or other solvent from a frozen biological product by sublimation. Sublimation refers to the process of solvents, such as water, like dry ice, which does not pass through a liquid state and changes from a solid to a gaseous state.

Advantages of freeze drying technology for laboratory freeze dryers
Drying methods are various, such as drying, boiling, drying, spray drying, and vacuum drying, but ordinary drying methods are usually carried out at temperatures above 0 ° C or higher. The products obtained by drying generally have problems of shrinking size and hardening of the texture. Most of the volatile components are lost, some heat-sensitive substances are denatured and deactivated, and some substances are even oxidized. Therefore, the dried product has a large difference in properties compared with that before drying. The freeze drying technology of the laboratory freeze dryer has the following advantages over the advantages of ordinary drying technology:

How to choose a suitable freeze dryer?
The principle of a freeze dryer is a technical method of preliminarily freezing an aqueous article and then sublimating its water under vacuum to obtain a dried article. The freeze-dried articles are easy to store for a long time, and can be restored to the state before lyophilization and retain the original biochemical characteristics after adding water.
