Vacuum Tray Dryer Model: AI-VTD is suitable for rapid drying of thermal sensitive materials easily resolved, polymerized of deteriorated under higher temperature. Sterilization can be conducted prior to the drying process, during which no matter is allowed to enter the product. Static vacuum dryer eliminates the configuration damage of the drying materials therefore widely used in pharmaceutical, chemicals and foodstuff etc.
Principally, drying under vacuum is environmentally friendly because the Evaporated Solvents can easily be re-condensed. These solvents can then either be recycled or disposed of without any problem.
Drying of solvents in Ex-proof ovens may solve the safety problem in the oven but not the environmental aspect. The solvent vapour is blown out of the oven through the exhaust system Furthermore, there is a risk of uncontrolled mixture formation.
