Fluid Bed Dryer
Fluid Bed Dryer offers a lucid solution to drying of wet granules, crystalline or course materials. It utilizes the principle of passing the hot air at a high velocity through the bed of the material to be dried, thus causing it to fluidize.
Operation
The blower situated on the exhaust side of the dryer operates no negative pressure principle, which creates the induced draught and sucks in the fresh air into the dryer. A stream of hot filtered air is introduced from the bottom of product container containing the wet material. This container is provided with the air distribution plate and Dutch sieve. The air stream is passed through the bed of the material and fluidizes the product particles by creating the turbulence in the product container. Due to fluidization each particle gets surrounded by hot air, which leads quick & uniform heating and drying. Filter bags provided at the top prevent escaping of particles from the machine.
The Capacity Ranging From 10 / 30 / 60 / 120 / 150 / 200 / 250 / 300 / 500 Kgs., with steam heating / electrical heating.
The conventional drying method of drying products in tray dryer is rather inadequate and trouble some. They occupy large floor space, have very high drying times, are labour intensive and offer uneven drying. On contrast Fluid Bed Dryer occupy comparatively lesser floor space, are very easy to operate & 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. Due to the reduce drying time high production rates are achieved.
As the product is in close contact with drying air at lowtemperature 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. Dueto the continuous movements of product during drying lumpformation, case hardening etc. are minimized.
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 liquids or pasty materials.

Dust Extractor-300
Operation
This equipment is most useful to transfer the material from container of FLUID BED DRYER to INTERMEDIATE PRODUCT CONTAINER. With help of this equipment dust free and very speedy material transfer from FBD bowl is possible. The equipment is equipped with one cone type container which is provided with clamping hooks to clamp the FBD bowl, rubber gasket for air tight fitting between FBD bowl and cone type container. The container is also have a butterfly valve at bottom to drain the material in required IPC or any other container. The hydraulic system (power pack unit with cylinder) is provided to lift the complete assembly with FBD bowl and tilt the pair of cone type container and FBD bowl at 180 degree.
With help of the hooks first clamp the FBD bowl with cone type container. Lift the whole assembly with FBD bowl at a desirable height. With help of hydro-mechanical system tilt the whole assembly at 180 degree. Finally all the material which was in the FBD bowl is transfer in cone container. Discharge the material in IPC or any other hopper, with help of butterfly valve which is provided at discharge of cone type container.
Suitability
- GMP point of view machine provided with S.S. Cladding base & S.S. Guards / Cover. No exposed painted surface. Hydraulic power pack is also covered with SS 304 cover.
- Very less material transfer time making the next operation earlier & save time and dust free system save environment of working area. The system can be operate by single operator.
- Contact parts SS304 provided as a standard. SS316/SS316 Lean be provided on demand.
