Vacuum Tray Dryer

A Vacuum Tray Dryer is used for drying high-grade, temperature-sensitive & oxygen-sensitive materials. It is highly suitable for drying hygroscopic substances, lumpy, glutinous, and products of low pomposity. It is widely used in the pharmaceutical, chemical, & food industries.

Vacuum Tray Dryer works under vacuum conditions on the conduction principle. Inside the dryer are several shelves; product is placed on these shelves in trays. The topmost shelf is a dummy shelf placed there to ensure proper heating and to prevent the dried powder from escaping into the solvent extraction system. The shelves are constructed hollow with baffles cum stiffeners placed in between shelves. Every shelf has an inlet and outlet nozzle and is connected to an inlet and outlet header through these nozzles. Hot medium is passed through these shelves through an inlet header and flows in a crisscross pattern, causing faster heat transfer.
