Despite the aforementioned strengths, fluidized bed dryers even have their restrictions. One of several more considerable limitations is their incompatibility with really gentle or fluffy products, as these could be blown out of your mattress via the upward flowing fuel.
If your fuel-particle constant is great, it can lead to productive warmth and mass transfer costs, which leads to more quickly elimination of dampness.

Maintenance and cleansing from the Fluidized Mattress Dryer might be done by routinely eliminate residue by wiping chamber just after use, wash filters with pH-neutral detergent, swap bags as wanted.
The bowl provides a perforated bottom that has a wire mesh for putting content to generally be dried. This bowl is placed at The underside of the dryer involving the drying chamber and also the air inlet chamber.
