40 square pharmaceutical freeze-drying machine vacuum system is introduced:
vacuum system by freeze-drying box & middot;
Condenser & middot;
Vacuum valve & middot;
Vacuum pump & middot;
Vacuum line & middot;
Vacuum measurement and other parts.
use vacuum pump group, formed a powerful suction capacity, formed in the drying chamber and condenser vacuum, on the one hand, make indoor moisture evaporation under vacuum drying chamber,
Sublimation)
, on the other hand, the vacuum system between the condenser and the drying chamber to form a vacuum gradient (
The pressure difference)
。
The chamber water after sublimation is captured by the condenser.
