Abstract

Multi-cell fluidization and atomization apparatus for the continuous production and/or coating of granules, for example in pharmaceutical and agricultural chemical industries, comprises a series of upright cylindrical cells through which the particulate material moves sequentially having inlet and outlet openings at various heights and rotary agitators therein. The material is fluidized in the cells and may also be contacted by an atomized liquid.
