Abstract
An agitated bed drying apparatus (20) for particulate material (152) is provided which includes a housing (22) having an elongated, essentially imperforate, 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). An infrared heating unit array (28) is located above the bed (24) so as to expose the particulate material (152) to IR radiation for most effective drying thereof. Alternately, the bed (24) may be in the form of a length of material (58) mounted in tension and against translation within housing (24), or as a continuous belt (136).
