The freeze dryer should be stored in a place with good ventilation and no corrosive gas.
Vacuum freeze-drying technology is the gentlest way to dry substances. It is based on the principle of sublimation, the physical phenomenon in which a solid state is directly transformed into a gaseous state.
The material is dried in a vacuum drying chamber, and the water vapor evaporated from the material is re-condensed into ice by the cold trap to achieve the purpose of eliminating water vapor.
The vacuum pump is only used to remove the air from the drying chamber and does not include water vapor.
The baffle is equipped with a heating device and transfers heat to the material through conduction to provide the energy required for sublimation.
When the free water in the material is sublimated, the bound water inside can also leave the material under very low vacuum. This drying process is considered the final stage of drying- analytical drying.
