ABSTRACT:
The invention provides a fluid bed conditioning apparatus (especially a dryer) which comprises a plurality of connected treatment zones, each zone having an apertured base and means for supplying a fluidized gas through said apertured base to each zone to cause material therein to be fluidized. The apparatus includes means for vibrating each apertured base and the zones are separated by movable partitions which are operable in conjunction with transfer means for urging material from one zone to an adjacent zone whereby the contents of a first treatment zone can be transferred to the adjacent zone after a desired treatment time in the first zone.
