ABSTRACT:
An agitated bed apparatus (20) for heating, cooling, and/or drying particulate material (152) is provided which includes a housing (22) having an elongated flexible bed (24) therein adapted to receive the material (152). An agitator assembly (26) made up of a series of rotatable beater bar units (70) is located below the bed (24) and oriented for repeatedly impacting the bed (24) to establish an undulating bed movement for elevation and tumbling of the particulate material (152). A material conditioning unit (156) such as an infrared heating unit array (28) is located above the bed (24) so as to expose the particulate material (152) to hot, cool, or ambient air for heating, drying, or cooling thereof. In another embodiment, the apparatus (20) includes a plurality of units (156) which are slidably removable from the housing (22) of the apparatus (20).
