Abstract
A granular material treating device. Included are a housing having an input end and an output end and a porous conveyor belt disposed within the housing so that a generally horizontally-disposed run of the belt extends between the input and the output ends of the housing. The belt is configured to be driven to convey granular material, positioned to a desired depth on the belt, from the input end to the output end of the housing. The device also includes a nozzle disposed beneath the run of the belt extending from the input end to the output end of the housing. The nozzle is oriented to blow a gas, at a pressure greater than ambient gas in the housing, upwardly through the belt run. A spout within the granular material is, thereby, created to effect stirring. Finally, the device includes a stave which extends downwardly into the granular material as it is conveyed along the belt. The stave is positioned forwardly of a location at which the spout it created to generate a void at the approximate location of the spout.
