Fluidized bed dryer ppt. It works on the principle of fluidization. The process air coming from the perforated bottom of the trough creates a homogeneous fluidized carpet. Fluidized bed dryer requires less time to complete drying. Freeze dryer product is frozen and water is removed by sublimation at low.
The fluid bed dryer is not suitable for drying liquids or pasty materials. Principle of the fluidized bed dryer a vibratory conveyor is leading the tobacco in an even layer through two drying zones. It facilitates the drying of thermolabile substances since the contact time for drying is short. The direct contact between particles and air gas is possible in fluid bed system.
They can be designed in either batch or continuous type fluid bed dryer. In heinen köhl standard process air will be conditioned in energy units following the closed loop principle. Hot spots are not observed in the dryer because of its excellent mixing and drying capacities. Powerpoint ppt presentation free to view.
