- 20Years Focus On Drying And Mixing Equipment
Principle
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 recovered. If the solvent is water, condenser might be canceled and the investment and every could be saved.
Features
●Under the condition of vacuum, the boiling point of raw material will decrease and make the evaporation efficiency higher. Therefore for a certain amount of heat transfer, the conducting area of dryer can be saved.
●The heat source for evaporation may be low pressure steam or surplus heat steam.
●The heat loss is less.
●Before drying, the treatment of disinfection may be carried out. During the period of drying, there is no impurity material mixed. It is in conformity with the requirement of GMP.
●It belongs to static dryer. So the shape of raw material to be dried should not be destroyed.
Application
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.

Note:
○ When ordering, please select the appropriate vacuum dryer according to the physical properties of the initial moisture content of the dry material, the temperature of the vacuum, the dryness of the drying time and other factors. 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 drying racks can be increased appropriately. Please promptly submit to our factory.。
○ The accessories in the vacuum drying system mentioned above in the instruction manual 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 user's vacuum drying system.。
○ The company's equipment implements quality three guarantees for users. All accessories, long-term supply, please rest assured。
