原 理 Principles

所谓真空干燥，就是将干燥物料处在真空条件下进行加热干燥，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;如采用SK系列水环真空泵，可不用冷凝器，节省能源投资。

The so-called vacuum drying refers to heating and drying thedried materials under vacuum conditions. If the vacuum pump isused for air extraction and dehumidification, the drying rate willbe accelerated.

Note: If a condenser is used, the solvent in the material can berecovered through the condenser. lf SK series water ringvacuum pump is adopted, condenser is not needed, thus savinoenergy investment.

应用 Applications

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。

lt is suitable for low-temperature drying of heat-sensitive materialswhich are easy to decompose, polymerize and deteriorate at hightemperature. lt is widely used in pharmaceutical, chemical, food.electronics and other industries.

特点Features

真空下物料溶液的沸点降低，使蒸发器的传热推动力增大，因此对一定的传热量可以节省蒸发器的传热面积。

蒸发操作的热源可采用低压蒸汽或废热蒸汽。

蒸发器热损失少。

在干燥前可进行消毒处理，干燥过程中无任何不纯物混入，符合GMP要求。

本干燥器属于静态真空干燥器，故干燥物料的形体不会损坏。

The boiling point of the material solution decreases under vacuum, which increases the heat transfer driving force of the evaporator, thus saving the heat transfer area of the evaporator for a certain amount of heat transfer.

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

Evaporator has less heat loss.

Disinfection can be carried out before drying. No impurity is mixed in during drying, which meets GMP requirements.

This dryer is a static vacuum dryer, so the dried material will not be damaged.
