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.
