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.

Product Container:
Made of S.S. 316 & provided with the S. S. bolliendr Sieve and perforated plate for proper air distribution.

Container Trolley:
Made up of S.S. 304 supported on caster wheels.

Filter Bag Housing:
Made up of S.S. 304. Consists of the finger shaped cotton filter bags. Explosion flap is provided at the back side of the explosion chamber to suppress the explosion pressure within the safety limits. Provided with pneumatic filter bag shaking mechanism.

Top Dish:
Made up of S.S.304.

I. D. Fan Assembly:
Centrifugal I. D. fan with S. S. 304 impeller blades & S. S. 304 casing. Mounted on top dish.

OPERATION
Fluid Bed Dryer is designed to introduce the hot air stream at the /base of the product container which is filled with the material. Induced draught is created by means of blower and fresh air is sucked into the unit. This hot air stream expands the material at certain velocity and creating turbulence in the product. The phenomenon is known as fluidisation and offer conditions which are almost for drying. Fluidisation produces full agitation of solid particles by hot air, heat transfer is extremely high and uniform. The product is dried fast without appreciable loss of heat. Filter bags prevent particle escaping from the dryer.

SUITABILITY
The conventional drying method of drying product in tray dryer is rather inadequate and troublesome. They occupy large floor pace, have very high drying time, are labour intensive and offer uneven drying. On contrast fluid Bed Dryer occupy comparatively lesser floor space, are very easy to operate and can dry material in least time as compared to tray dryer.

In Fluid Bed Dryer, temperature distribution throughout the product is uniform and the heat transfer rate is very high. Due to the reduced drying time high production rates are achieved.

As the product is in close contact with the 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.
