5. Fluidized bed dryer requires less time to complete drying. i.e., 20 to 40 min. Hot spots are not observed in the dryer, because of its excellent mixing and drying capacities. The thermal efficiency is 2 to 6 times greater than tray dryer. It facilitates the drying of thermolabile substances, since the contact time for drying is short. It can be used either as batch type or …

Tray dryer I Diagram I working principle | PPT
6. Working: In tray dryer, hot air is continuously circulated. Forced convection heating takes place to remove moister from the solids placed in trays. Simultaneously the moist air is removed partially. Wet solid is loaded into the trays. Trays are placed in the chamber. Fresh air is introduced through the inlet, which passes through the heaters and gets heated up.
