所谓真空干燥，就是将干燥物料在真空条件进行加热干燥，如果利用真空泵进行抽气抽湿，则加快了干燥速率。注：如采用冷凝器，物料中的溶剂可通过冷凝器加以回收；如溶剂为水，可不用冷凝器，节省能源投资、�/p>

It is well known that vacuum drying is to put raw material under the

state of vacuum for heating and drying. If use vacuum to pump air and

humidity out, the dry speed will be faster.

Note: if use condenser, the solvent in raw material can be recov-

ered. If the solvent is water, condenser might be canceled and the

investment and energy could be saved.

适用于在高温下易分解，聚合和变质的热敏性物料的低温干燥;被广泛地采用在制药、化工、食品、电子等行业、�/p>

It is suitable for drying heat sensitive raw materials that can decompose or polymerize or deteriorate at high temperature.

It is widely used in pharmaceutical, chemical, foodstuff and electronic industries.
