Fluid Bed Dryer

Fluid Bed Dryer

The capacity ranging from 10 / 30 / 60 / 120 / 150 / 200 / 250 / 300 / 500 Kgs., with steam heating / electrical heating & thermal heating facility.

Electrically / Steam & Thermic Fluid Heated in which general structure, made out of mild steel & painted in Standard Model & made out of S.S.304 quality material & polished to the matt finished in GMP Model, but contact parts i.e. Product Container and Retarding Chamber, are made out of S.S.304 / S.S. 316 quality material, with Non-Flameproof blower motor, (Flameproof motor provided on demand) suitable to dry wet material.

Three Piece GMP Mode


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 in to the unit. The fresh air is heat by means of electrical heaters or steam or thermic fluid heaters. This hot air stream expands the bed of material at certain velocity & creating turbulance in the product. The phenomenon is known as fluidisation and offer conditions which are almost ideal for drying. Fluidisation 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.


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 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.

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.

Lifting and Tipling Device for Fluid Bed Dryer`s Container

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.

  • 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. SS 316 / SS 316 L can be provided on demand.
