Description of Vacuum Tray Dryer

Vacuum Tray Dryer is a most often used static chamber dryer under vacuum condition. Inside the drying chamber, trays loaded with wet material are placed on top of each other in a drying shelf.

In drying process, heat medium, such as steam, hot water or thermal oil, is connected to the drying shelf which transfers heat to wet material. Under vacuum condition, boiling point of moisture is much lower. So the moisture can be evaporated under low temperature. The vacuum pump constantly sucks out the evaporated moisture to speed the drying process. Vacuum pump, tubular condenser and buffer tank are equipped to recover the evaporated moisture.

Features of vacuum tray dryer

1) Flexibility in heat medium: Heat mediums can be steam, hot water or thermal oil to obtain different temperature according to special drying requirements.
2) Uniform drying: Four exhaust vents are equipped to make sure the evaporated moisture can be sucked out immediately.
3) Energy saving: The boiling point of moisture is much lower under vacuum. Low drying temperature can reach high evaporation rate.
4) GMP standard: Drying chamber is fully welded without dead corners to meet GMP standard.

Application of Vacuum tray dryer

This machine is mainly used for drying fruits, vegetables, herbal plants, herbal extracts, heat sensitivity materials such as explosive, the materials that state is not stable and shape is easy to be destroyed, the materials that need to recover organic solvent such as ethanol, etc.
