four. The air velocity is improved with time. If the velocity on the air is greater than the settling velocity with the granules, the granule remains partly suspended within the air stream.
The air inlet chamber features a contemporary air inlet, prefilter, and heat exchanger connected serially to warmth the air towards the demanded temperature. The new air and exit air temperature are usually monitored in situ. Temperature sensors.
Hybrid Fluidized Bed Dryers: These dryers combine functions of fluidized bed and other sorts of dryers, for instance tray dryers or rotary dryers.
All parameters on the tools like the speed of move, operating temperature are adjustable with the assistance of a control panel.
Maintenance and cleaning of the Fluidized Mattress Dryer could be done by consistently take out residue by wiping chamber soon after use, wash filters with pH-neutral detergent, switch baggage as wanted.
