Like conventional fluid bed dryers, vibrating fluid bed dryers function by passing a process gas directly through a bed of solids via a perforated plate or another type of fluidizing media. Vibration is added to aid in fluidization of more difficult materials.
Vibrating fluid bed dryers are well suited for:
Material that has a wide particle size distribution - fluid bed dryer vibration will help to discharge oversize particles that will not fluidize.
Sluggish or sticky materials.
Temperature sensitive materials - a sub-fluidized condition can be created to produce plug flow and eliminate burning or discoloration of individual particles.
Fragile materials - low amplitude fluid bed dryer vibration and reduced fluidizing velocity create a gentle bed, which causes less degradation than conventional fluid bed dryers or other mechanical dryers.
