PSVD Plate Shelf Vacuum Tray Dryer
Product Descriptions
In the drying chamber, material will be dried under vacuum condition. Under the vacuum condition, the boiling point of material solution will reduce. It will increase impetus for heat and mass exchange. Therefore for certain heat exchange amount, it can save heat exchange area of evaporator.
Material is under static condition during operation of the equipment, which is benefit for keeping initial status of material. Intermittent operation can adjust process conditions at any time.
On the top of Pharmaceutical vacuum dryer, heating system is arranged to tackle the problem of return of condensed water, in addition, air suction is arranged at the side to improve drying efficiency.
This equipment can be used for low temperature drying and organic solvent recovery. Heat source can be steam, hot water and thermal oil. It is specially suitable for drying materials that is easily oxygenated during drying.
Working Principle
PSVD series vacuum shelf 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 pocess, 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.
Product Application
Pharmaceutical vacuum dryer is Suitable for drying of thermal sensitive materials easily resolved. Polymerized or deteriorated under higher temperature and it is wide used in pharmaceutical, chemical, foodstuff and electronic industries.
