Vacuum microwave drying device is an item collection electronics, vacuum, the machinery of corresponding vacuum microwave drying technology and life
The new high-tech product that a variety of subjects such as, thermodynamics, program-controlled are integrated is that the physics to substance becomes in the drying process
Under change, the exchange of inside and outside caloic and vacuum condition on the basis of the further investigation of water translocation process, one to grow up is new
Technology, new process.Vacuum microwave drying device has the advantages such as dry yield is high, high-quality, and processing cost is low, however, certain
Special material or drug will appear during vacuum microwave drying have peculiar smell and or active ingredient overflow the case where, effectively at
Divide to overflow and can reduce drug effect;And ambient enviroment can be generated pollution by peculiar smell occur, be would have to meet environmental requirement enterprise
Peculiar smell eliminating equipment is installed, which improves except useless cost.
