Fluidized bed dryers are widely Employed in a variety of industries for drying granular and powdered components. The basic principle includes suspending the fabric within a stream of air or fuel, creating a fluidized point out that improves the drying procedure.
Nevertheless, the strong particles are blown-up and keep on being suspended within the air channel, If air is allowed to move through a bed of solid product inside the upward course by using a velocity higher compared to the settling price from the patches.
The air is filtered in the filter and afterwards passes throughout the mattress of the material at The underside.
Also Be certain that the appropriate Functioning of HVAC system by checking the tension differential of spot & temperature and RH.
