Principle
The WZ Microwave Vacuum Dryer under the condition of vacuum, material put on the hanging shelf made revolving motion will absorb the energy of microwave and make moisture inside material evaporate quickly under low temperature state and reach the purpose of drying. Because the heating source is microwave so evaporate the moisture from interior of materials, so it have fast drying speed. And under the vacuum state, the drying temperature is very lower.
Feature
1. Besides advantages of microwave heating drying equipment, such as quick heating speed, high thermal efficiency, 100% of material recovery.
2. Material making revolving motion, the energy of microwave received by material is constant basically. It avoids the phenomenon such as some materials are too dry and carbonization but the others are not dry.
3. Its structure is compact and it occupies small area.
4. The inner wall of container is smooth and does not exist dead corner and is easy to clean and conforms to the requirements of "GMP".
5. HMI and PLC control system, motor speed is controlled by VFD, and all process parameters can be recorded.
6. This machine adopts PLC automatic control, all the operation according to the requirements of the user to set the process parameters automatically, it can print all the process parameters, the original record is true and reliable. In full compliance with the GMP requirement of pharmaceutical production.
Applications
For drying all kinds of Chinese traditional medicine pill, it has low energy consumption and high output. Compared with helicoids vibration fluidized bed and plane vibration fluidized bed, its energy consumption will be 1/3 only.
