Fluid Bed Dryer is a widely used in pharmaceutical industry for highly efficient, dust free, fast, gentle & uniform,drying of granulated materials obtained from wet granulation.

Process concept :

The drying is achieved through a combination of moisture diffusion from the solid material to the heated air stream and the removal of that moisture by forced air convection. the product to be dried is transformed into low expanding fluidized bed with the aid of drying air added from below by means of specialized inlet air distributor. In this condition, the particles are isolated from one another and kept in constant motion. The high specific surface of the fluidized product helps great amounts of heat transfer.

A special effective air flow during fluidizations allows to pass through the entire surface of every single particle. FBD is manufactured for over pressure integrity using a unique sealing system for operator safety and product containment.

Fluid Bed Dryers are manufactured in various capacities and batch sizes. Batch size means the weight of wet product i. e. including moisture / solvent that can be charged in the dryer at a time. In case of very granular or crystalline material the capacity may be increased by about 15 to 20% . The capacity depends upon the material characteristic (i.e. Crystalline or amorphous), bulk density,Moisture content, hygroscopic nature etc.

We offer Fluid Bed Dryers of capacities 5 kgs to 300 Kgs.
