The wet solids are lifted from The underside and suspended inside a stream of air (fluidized state). As the hot air passes between the particles it will require the excess humidity within the particles Consequently drying the particles.
Air inlet: The bowl is then pushed into your dryer, and contemporary filtered air is permitted to pass through a prefilter, which receives heated by passing through a heat exchanger. Concurrently, an exhaust supporter is allowed to rotate.
Routine maintenance and cleansing from the Fluidized Mattress Dryer is usually done by routinely eliminate residue by wiping chamber following use, wash filters with pH-neutral detergent, change baggage as needed.
