DESIGN OF FLUIDIZED BED DRYER - IRJET

2021-3-27  fluidized bed is a physical phenomenon occurring when a quantity of a solid particulate substance (usually present in a holding vessel) is placed under appropriate conditions to cause a solid/fluid mixture to behave as a fluid. This is usually achieved by the introduction of pressurized fluid through the particulate medium. This results in the medium then having many properties and characteristics of normal fluids, such as the ability to free-flow under gravity, or to be pumped using fluid

Fluidized Bed Dryer DF - petkus

2015-11-19  The PETKUS Fluidized Bed Dryer ensures that desired optimal residual moisture levels can be realized. Drying occurs based on the vibrating flui - dized bed principle whereby warm air flows through the fluidized product and absorbs moisture as water evaporates from the surface of the kernels. The moist air then flows onward through the air outlet.
