Inert bed content: at times accustomed to improve the fluidization with the merchandise, especially if the product or service is incredibly mild or has bad flowability.
Temperature: Elevated temperature brings about increased humidity diffusivity and consequently greater drying rate and lessened drying time. The nature of the material plays an essential purpose in selecting the operating temperature.
In the case on the FBD process, air or gasoline is accustomed to fluidize the mattress of particles. This fluidization produces a turbulent and agitated ecosystem, permitting for economical heat and mass transfer.
While, The underside from the chamber includes a mesh/ perforated sheet for passage of of incredibly hot air through the plenum chamber, the best is straight connected to The underside on the Fluidization Chamber (also referred to as Growth Chamber) with the assistance of a D type hollow tube inflatable gasket.
