Product Profile of Batch Type Vacuum Tray Dryer

Batch type Vacuum Tray Dryer is mainly used for drying of high grade, temperature and oxygen sensitive products. The Vacuum Tray Dryer is most suitable for drying hygroscopic substances, which are dried to very low residual moisture, content level. The Vacuum Tray Dryer utilises frequently vacuum drying cabinets for drying lumpy, glutinous products or products of low pomposity. Batch type Vacuum Tray Dryer can also be used for drying of thermal sensitive materials easily resolved, polymerized or deteriorated under higher temperature.

Key Features of Batch Type Vacuum Tray Dryer

• Vacuum Tray dryer is commonly used batch dryer
• Vacuum Tray dryer is box-shaped and loaded and unloaded via a door
• Inside section has several heating plates mounted one above the other on which the product is placed in trays
• The bottoms of both heating plates and trays should be as smooth as possible to permit optimal heat transfer between plates and product
• The medium flowing through the heating plates is water, steam or thermal oil
• Frequently vacuum drying cabinets are utilised for drying lumpy, glutinous products or products of low pomposity
• The distance between the heating plates is determined primarily by the surface loading and the foaming of the product
• To avoid retrograde condensation the cabinet walls are indirectly preheated by the heating plates
• During the main drying phase the vacuum is in the range of 40 to 80 mbar abs and in the final drying phase vacuums of only few mbar abs are reached
• For some products the vacuum and temperature profiles are automatically controlled in order to prevent a pass over of the critical product temperature.
• On completion of the drying, the product can be cooled by circulating of cooling water through the heating plates
