Low temperature vacuum tray dryer machine

Description of Vacuum Tray Dryer

Vacuum drying refers to dry the materials under vacuum condition, and use vacuum pump to extract air and wet, thus accelerating drying rate. YZG round Vacuum Dryer and FZG square vacuum dryer belong to static Vacuum Drying Machine. Under vacuum conditions, the boiling point of material solvent is reduced, making this machine to dry unstable or thermosensitive materials. Additionally, the vacuum dryers have excellent sealing ability, so they are also used for drying the materials requiring solvent recovery or materials with poisonous gas.

Features of vacuum Tray Dryer

1. Under the condition of vacuum,the boiling point of raw material will decrease and make the evaporation efficiency increase. Therefore for a certain amount of heat transfer, the conducting area of dryer can be saved.
2. The heat source for evaporation may be low pressure steam or surplus heat steam.
3. The heat loss is less.
4. Before drying,the treatment of disinfection may be carried out during the period of drying,there is no impurity material mixed. It is in conformity.
5. It belongs to static dryer. So the shape of raw material to be dried should not be destroyed.

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.
