原理

所謂真空干燥，就是將干燥物料處在真空條件下，進行加熱干燥，如果利用真空泵進行抽氣抽濕，則加快了干燥速率。

注：如采用冷凝器，物料中的溶劑可通過冷凝器加以回收；如采用SK系列水環真空泵，可不用冷凝器，節省能源投資。

Principle

Vacuum drying means to heat the materials to be dried under vacuum conditions. If a vacuum pump is used for air evacuation and humidity removal, the drying speed will be increased.

Note: If a condenser is adopted, the solvent in the materials can be recovered through the condenser. It the SK series water loop vacuum pump is adopted, there is no need to use the condenser, so that energy is saved.

技術特點

●真空下物料溶液的沸點降低，使蒸發器的傳熱推動力增大，因此對一定的傳熱量可以節省蒸發器的傳熱面積。

●蒸發操作的熱源可采用低壓蒸汽或廢熱蒸汽。

●蒸發器熱損失少。

●在干燥前可進行消毒處理，干燥過程中無任何不純物混入，符合GMP要求。

●屬于靜態真空干燥器，故干燥物料的形體不會損壞。

Technical features

●Under vacuum, the material solution boiling point decreases, and the heat transfer driving force increases, so that heat transfer area of the evaporator can be saved.

●The heat source for evaporation can be low pressure steam or waste heat steam.

●The evaporator heat loss is low.

●The machine can carry out sterilization before drying, and does not have any impurities during drying, conforming to GMP requirements.

●The machine is a static vacuum dryer. Therefore, the shape of dried materials will not be damaged.
