It permits successfully performing operations such as: drying, heating, cooling, reacting, dedusting or agglomerating in the same unit, through multiple zones, with independent control of air flow temperature, dew point, dew point and fluidizing speed. The fluid bed operates gently but efficiently under the direct drying principle through intimate contact between heated gas/air and the product, to effect heat and mass transfer. The process steam enters through the fluid bed air plenum passing through the gas distributor plates, which trap the solids. Fluidization enables the product to flow continuously through the fluid bed, reaching the opposite end; it is used for handling heat sensitive or toxic products, or which are oxygen sensitive, or materials with inflammable liquid solvent. The unit mainly consists of:
fluidizing surface made of microdrilled plate
pressurization chamber for fluidization air
static chamber for exhaust air
vibration source with alternate-current powered vibrators
vibration-intensity control and regulation system by frequency converter
fluidization-air fan complete with air-flow rate regulation unit
heat generator
discharge valve
support structure with vibration-damping joints.
