Vacuum Tray Dryer (VTD)

Vacuum Tray Dryer works under vacuum conditions on the conduction principle. Inside the dryer are several shelves having trays on which the products are placed. Top most shelf is a dummy shelf placed there to ensure proper heating and to prevent the dried powder from escaping into the solvent extraction system. 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.

Advantages of the Vacuum tray dryers:

  1. Very efficient heat sensitive
  2. Materials can be dryers in containers or enclosures
  3. Average drying temperature is much lower than standard dryers
  4. Drying action becomes faster as heat is easily transferred throughout the body of the dryers, due to its large surface area
  5. Dries large moisture as compared to normal dryers
  6. Quality of dries material is better than that of the normal dryers
