Working principle
The so-called vacuum drying is drying the material under vacuum conditions and performing heat drying. If vacuum pumping is used for dehumidification, the drying speed is accelerated.
Note: If using a condenser. The solvent in the material can be recovered through the condenser. If the solvent is water, the condenser can be used without saving energy investment.

Performance characteristics
◎ The boiling point of the material solution under vacuum is reduced. Increases 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 little heat loss.
◎ It can be disinfected before drying. No impurities are contaminated in the drying process. It meets GMP requirements.
◎ belongs to static vacuum dryer. Therefore, the shape of the dried material will not be damaged.

Adapt to the material
It is suitable for low-temperature drying of heat-sensitive materials that are easily decomposed, polymerized and degraded under high temperature; it is widely used in pharmaceutical, chemical, food, electronics and other industries.

◎When ordering, please select the proper vacuum dryer according to the factors such as the initial moisture content of the dried material, the final moisture content, the temperature, the vacuum degree, the drying amount, and the drying time. The same type of vacuum dryer has four heating methods: steam, hot water, thermal oil, and electric heating. For example, in order to increase the amount of drying can be appropriate to increase the number of drying rack please promptly to our factory.
◎ The accessories in the vacuum drying system mentioned in the user's manual can be provided and installed for users. Please specify when ordering.
◎The company can provide design, manufacture and installation of special requirements in the vacuum drying system proposed by users.
