Abstract: A thermal processing apparatus (20) includes a spiral conveyor system (22) configured into an ascending spiral stack (26). An inner mezzanine (40) is disposed within the circular interior of the stack (26) and an exterior mezzanine (42) encircles the spiral stack. The mezzanines divide the processing chamber (32) into a plurality of processing zones. A sealing system (90) seals the interior mezzanine (40) relative to the spiral stack (26). A sealing system (130) seals the outer mezzanine (42) relative to the exterior of the spiral stack, and a seal system (132) seals the outer mezzanine relative to the walls (56, 58) of the housing, thereby to limit the leakage of the processing fluid between the mezzanines and the spiral stack (26) and housing walls so that as much as the thermal processing medium is possible is forced through the spiral stack for processing work products carried on the conveyor system (22).

Abstract: The bottom tier (24) of a conveyor belt (22) arranged in a spiral stack (26) is supported by and driven by inner and outer drive chains (28) and (30). The inner and outer drive chains are supported on and ride along support rails (32) and (34). The inner and outer drive chains are driven by a drive system (35) composed of inner and outer drive systems (36) and (38), each including a drive motor with a drive gear engaged with the inner and outer drive chains. Each of the motors is controlled by a separate variable frequency drive unit (114) and (116) which in turn are controlled by a control system (44). The control system (44) also controls the operation of a lubrication system (40) that supplies lubricant to the drive chains.

Abstract: A conveyor belt (36) is arranged in at least one spiral conveyor unit (32) or (34) is arranged in tiers forming at ascending spiral stack (38) and/or a descending spiral stack (40). A ceiling or top sheet (58) is positioned over the spiral stack. A circulation fan (60, 62) draws spent thermal processing medium laterally from the tiers of the spiral stack, up the exterior of the stack and across the top of the stack above the ceiling or top sheet and through a heat exchanger (64) located above the ceiling. The treated thermal processing medium is then routed across the remainder of the diameter of the spiral stack and then down the side of the spiral stack diametrically opposite to the circulating fan thereby to enter the spiral stack in a lateral direction diametrically toward the circulating fan. At least one opening (70, 100, 200) is formed in the ceiling between the heat exchanger and the diametrically distal end of the spiral stack from the circulating fan thereby to provide an alternative flow path for a portion of the thermal processing medium to enter the spiral stack from above, thereby resulting in more uniform treatment of the work product being carried by the conveyor of the spiral stack.

Abstract: A thermal processing apparatus (20) includes a spiral conveyor system (22) configured into an ascending spiral stack (26). An air balance tunnel (40) includes a tunnel housing (76) positioned inside of a thermal processing chamber adjacent an outlet opening (36). A conveyor belt (24) travels through the housing on its way out of the processing chamber. An air pervious ejector assembly (78) is positioned within the housing at an elevation above the conveyor belt (24). An air pervious evacuation sheet (80) is located within the housing at a location beneath the conveyor belt (24). An air pervious cover assembly (150) is positioned over the conveyor belt (24) at a location just before the conveyor belt enters the air balance tunnel (40). The cover sheet (150) is connectable to the ejector assembly (78) so as to remove the ejector assembly from the tunnel housing (76) by manually moving the cover assembly (150).
