The so-called vacuum drying is to heat and dry the dried materials under vacuum conditions. If a vacuum pump is used to extract air and moisture, the drying speed will be accelerated.
Note: If a condenser is used. The solvent in the material can be recovered through the condenser. If the solvent is water, the condenser can be omitted, saving energy investment.
◎The boiling point of the material solution is reduced under vacuum. Increase the heat transfer driving force of the evaporator. Therefore, the heat transfer area of the evaporator can be saved for a certain amount of heat transfer.
◎The heat source for evaporation operation can be low pressure steam or waste heat steam.
◎The evaporator has less heat loss.
◎It can be disinfected before drying, and there is no impurities in the drying process, which meets the requirements of GMP.
◎It is a static vacuum dryer. Therefore, the shape of the dried material will not be damaged.
Adapt to materials
It is suitable for low-temperature drying of heat-sensitive materials that are easy to decompose, polymerize and deteriorate at high temperatures; it is widely used in the pharmaceutical, chemical, food, and electronic industries.

◎When ordering, please select a suitable vacuum dryer according to factors such as the initial moisture content and final moisture content of the material to be dried, temperature, vacuum degree, drying capacity, and drying time. The vacuum dryer of the same model has four heating methods: steam, hot water, heat transfer oil, electric heating. For example, in order to increase the drying capacity, the number of drying racks can be appropriately increased. Please submit it to our factory in time.
◎The accessories in the vacuum drying system mentioned in the instruction manual can be provided and installed by our factory for users. Please specify when ordering.
◎The company can provide design, manufacture and installation for the special requirements in the vacuum drying system proposed by the user.
◎The company's equipment implements three quality guarantees for users. All accessories are provided for a long time, please rest assured.
