Vacuum Tray Dryer Working Principle

Vacuum Tray Dryer is used mainly for drying high-grade, temperature, and oxygen-sensitive products. Vacuum Tray Dryer is highly suitable for drying hygroscopic substances, which are dried to very low residual moisture, content levels. Frequently vacuum drying cabinets are the sole possibility for drying lumpy, glutinous products or products of low pomposity.
It’s also suitable for drying thermal-sensitive materials that easily resolved, polymerized, or deteriorated under higher temperatures. 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, foodstuff, etc.
