FLUID BED DRYER (FBD)  

Dust free, fast, gentle, uniform, effective drying. A special effective air flow during fluidizations allows to pass through the entire surface of every single particle. Great drying efficiency for a perfect and uniform granule. GEM's FBD is manufactured for overpressure integrity using a unique sealing system for operator safety and product containment.

GEM's Fluid bed dryer is a process unit for preparation of granulated materials for solid dosage forms in batch and continuous batch operations. The system is applied for drying, agglomerations and top spraying upon fluidised bed. Fluid Bed Dryers are manufactured in various capacities & 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.GEM supplies FBD of capacities 1 Kgs to 300kgs. Fluid Bed Dryer consists of: -

•  Bottom chamber
•  Product container
•  Expansion chamber
•  Retarding and Filter Bag Chamber with lateral Support.
•  Air Supply Unit - Inlet Air plenum & its interconnecting duct
•  Exhaust blower with its interconnecting duct.
•  Relief / Return duct
