Fluid Bed Dryer: Working Principle In a fluidized bed dryer, hot air is introduced at high pressure through a perforated bed of moist solid particulate. The wet solids are sieved from the bottom and suspended in a stream of air (known as a fluidized state). Heat transfer is accomplished by direct contact between the wet solid and hot gases.

Fluidized bed - Wikipedia

A fluidized bed is a physical phenomenon occurring when a quantity of a solid particulate substance 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

A Study of Efficient Drying Parameters for Bed Dryers

The ASAE S448 DEC98 standard states that the bed shall not exceed 3 layers of particles and the airflow should be at least 0.3 meters per second (ASAE Standards, 1998). The drying area is set to be 0.1246 square meters. The dryer wall is set to be adiabatic. The temperature range of the dryer may vary from 290 Kelvin to 370 Kelvin.
