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).

Abstract: An assembly for managing product overblow in a gas treatment system may include a first deflector assembly configured to substantially prevent product from leaving a product treatment zone of a product carrying unit of the gas treatment system. The assembly may further include a second deflector assembly configured to substantially direct overblown product that has left the product treatment zone into an overblow landing area separate from a heat exchanger assembly of the gas treatment system.

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.
