Fluidized bed dryers are broadly used in numerous industries for drying granular and powdered supplies. The basic principle requires suspending the material inside a stream of air or gas, making a fluidized point out that boosts the drying method.
Despite the aforementioned benefits, fluidized mattress dryers even have their limits. Among the more significant limitations is their incompatibility with quite light or fluffy elements, as these may very well be blown out of your mattress through the upward flowing fuel.
A fluidized bed dryer functions by passing Incredibly hot air with higher force through a perforated mattress of moist reliable particles. The hot air passes at a velocity better as opposed to settling velocity in the particles resulting, particles beginning to suspend inside the air.
Total, while the fluidized mattress dryer is usually a potent piece of kit in drying processes, certain constraints needs to be viewed as prior to their implementation.
Alternatively, vacuum conveying could be performed by connecting the product container that has a tube and creating damaging force for suction utilizing a vacuum transfer system. Following drying, the next procedure is milling.
These developments resulted in the broader acceptance of fluidized bed dryers in many industries including pharmaceuticals, food processing, and chemicals.
