fluid bed dryer india

The fluid Bed Dryer are most suitable for drying granular crystalline, coarse or similar material in pharmaceuticals, fine chemicals, dyes, food and allied products. The fluid Bed dryer is not suitable for drying liquid or pasty materials.

• Fluid bed dryer is designed to introduce the hot air stream at the base of the product container which is filled with the Fluid Bed Dryer material.

• Induced draught is created by means of blower and fresh air is sucked in to the unit. This hot air system expands the bed of material at certain velocity & creating turbulence in the product. The phenomenon is known as fluidization and offer conditions which are almost ideal for drying.

• Fluidization produces full agitation of solid particles and since each particle gets surrounded by hot air, heat transfer is extremely high and uniform.

• The product is dried fast without appreciable loss of heat. Filter bags prevent particles escaping from the dryer.

• Fluid Bed Dryer occupy lesser floor space compare to conventional dryer and are very easy to operate and can dry material in least time as compared to tray dryer.

• In fluid Bed Dryer, temperature distribution through out the product is uniform and the heat transfer rate is very high. High production rates are achieved due to reduce drying time.

• As the product is in close contact with drying air at low temperature and also for short duration, the physical and chemical properties of the products are generally not effected and therefore the dryer can effectively be used for heat sensitive products.

• Due to the continuous movements of product during drying lump formation, case hardening etc. are minimized.
