ABSTRACT:
Improved material treatment apparatus includes an array of nozzles extending downwardly towards pan structure arranged for the substantially horizontal conveyance of solid particulate material. Gas is flowed through the nozzles at high velocity in an array of directed downwardly gas jets. The pan structure is gas impervious and impinging gas is deflected outwardly and upwardly through the bed of particles in fluidizing action and then exhausted at low velocity such that there is no significant particle entrainment in the exhaust gas stream. The angle of gas jets to the pan structure is at a small offset from the normal to the pan structure (less than ten degrees) and the small but effective resultant horizontal component of gas velocity is effective to modify the rate of movement of the particulate material through the treatment zone while maintaining the gas jet particle fluidization and treatment action in the treatment zone.
