Fluidized bed dryer ppt.
Spray dryer spraying atomization of product increases surface area of contact with hot air for drying.
The direct contact between particles and air gas is possible in fluid bed system.
The fluid bed dryer is not suitable for drying liquids or pasty materials.
The thermal efficiency is 2 to 6 times greater than tray dryer.
Principle of the fluidized bed dryer a vibratory conveyor is leading the tobacco in an even layer through two drying zones.
I e 20 to 40 min.

The process air coming from the perforated bottom of the trough creates a homogeneous fluidized carpet.
Here any type of inert gas or air is used.
In heinen köhl standard process air will be conditioned in energy units following the closed loop principle.
The fluid bed dryer is used for drying granular crystalline coarse or similar material in pharmaceutical fine chemicals dyes food and allied products.
Hot spots are not observed in the dryer because of its excellent mixing and drying capacities.
Freeze dryer product is frozen and water is removed by sublimation at low.
It facilitates the drying of thermolabile substances since the contact time for drying is short.
It works on the principle of fluidization.
Numerical studies of a fluidized bed for ife target layering numerical studies of a fluidized bed for ife target layering presented by kurt j.
Fluidized bed dryer requires less time to complete drying.
