Fluid bed drying is a commonly used process in pharmaceutical industry due to its highly efficient drying of granulated material obtained from wet granulation.
Fluid bed drying is a commonly used process in pharmaceutical industry due to its highly efficient drying of granulated material obtained from wet granulation.
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.
