In agitated fluidized bed dryers, additional mechanical agitation is released towards the fluidized bed to enhance the mixing and drying procedure. This sort is usually applied when materials have bad fluidization characteristics.
Which in essence ensures that we're simply using the fluidization for the goal of better area of heat transfer. Consequently, the flow fee of Incredibly hot Air is selected accordingly (using into account the soaked substance properties along with the drag power designed).
The dryer is generally manufactured up of stainless-steel. A detachable bowl is hooked up at the base in the dryer that is used for loading and unloading of material. The stainless steel bowl features a perforated foundation of a wire mesh supporting for substance that's getting dried.
Moisture Elimination: The moisture-laden air rises from the fluidized bed, carrying the evaporated dampness with it. This steady circulation of air throughout the mattress ensures uniform drying.
