FZG square vacuum dryer
working principle
The so-called vacuum drying is to dry the material under vacuum and heat it. If the vacuum pump is used for pumping and dehumidifying, the drying speed is increased.
Note: If using a condenser. The solvent in the material can be recovered by a condenser. If the solvent is water, the condenser can be used, saving energy investment.
Performance characteristics
◎The boiling point of the material solution under vacuum is reduced. 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 the evaporation operation may use low pressure steam or waste heat steam.
◎The evaporator has less heat loss.
◎ It can be disinfected before drying. There is no impurity in the drying process, which meets GMP requirements.
◎ is a static vacuum dryer. Therefore, the shape of the dried material will not be damaged.
Adaptable material
It is suitable for low temperature drying of heat sensitive materials which are easy to decompose, polymerize and deteriorate at high temperature; it is widely used in pharmaceutical, chemical, food, electronics and other industries.

◎ When ordering, please select the appropriate vacuum dryer according to the physical properties of the initial moisture content of the dry material, the final moisture content of the vacuum, and the drying time of the vacuum drying amount. In the same type of vacuum dryer, there are four types of heating methods: steam hot water heat conduction oil and electric heating. For example, in order to increase the amount of drying, the number of layers of the drying rack can be appropriately increased. Please promptly submit it to our factory.
◎In the instruction manual, the accessories in the vacuum drying system mentioned above can be supplied and installed by the user. Please specify when ordering.
◎The company can provide design, manufacture and installation for the special requirements of the vacuum drying system proposed by the user.
◎The company's equipment implements quality three guarantees for users. All accessories, long-term supply, please rest assured.
