I.Introduction of Fluid Bed Dryer
Fluid bed dryers use fluidization technology. Compared with the belt dryer and rotated drum dryer, fluid bed dryer converts materials from a static solid state to a dynamic fluid form during drying process. Fluid bed dryer consists of a stainless steel chamber with a removable perforated bottom. The steady air flow lifts and suspends the wet foods/snacks, and the resulting heat-transfer evaporates the water. Fluid bed dryer improves drying speed and temperature accuracy through precise control of the process-parameters.
II.Advantage
Compared with multi-layer predryer, fluidized bed is more effective for drying light and small granules.
Adopting pulsating for air intake, fluid bed dryer dries evenly and fast, ensuring perfect quality of specific foods.
Sticking is avoided under the fluidized air.
Damage risk is minimal without using mechanical stirring
