Abstract: An improved airflow delivery system (1) comprising an air moving element (3) configured to move air in a flow path, a chamber (19) in the flow path configured to receive product (9), an air transfer chamber (11) comprising an inlet (10) of a selected area for receiving air in the flow path in a first direction (x-x) and an outlet (14) of a selected area greater than the area of the inlet for discharging air in the flow path in a second direction (y-y) different from the first direction, an airflow divider (33) extending across the air transfer outlet and configured to divide airflow in the flow path, an airflow directional (15) extending across the flow path downstream of the airflow divider and upstream of the chamber, the airflow directional having an upstream inlet face (28a) and a downstream outlet face (29c) and configured to receive airflow at the inlet face and split the airflow into multiple separated sub-paths (27) within the flow path and to discharge the airflow from the downstream outlet face subs

Abstract: An improved oven (1) comprising a conveyor configured and arranged to move a product (11) to be processed through an oven, a primary air delivery system (45) configured and arranged to provide a heated primary air flow (47), a secondary air delivery system configured and arranged to provide a heated secondary air flow (48), a processing enclosure (21) configured and arranged to receive and contain the product and the primary air flow, an insulated enclosure (2) configured and arranged to receive the heated secondary air flow, the processing enclosure configured and arranged to extend through the insulated enclosure and the heated secondary air flow and to separate the primary air flow from the secondary air flow.

Abstract: A rotary tube furnace (1) comprising an insulated heating chamber (4), the insulated heating chamber having a product discharge outlet (21) and a process tube inlet (39), a heating element (14) operatively arranged to selectively heat the heating chamber, a generally horizontally extending process tube (2) supported for rotation relative to the heating chamber, the process tube having a first portion (36) generally arranged outside of the heating chamber and a cantilevered second portion (37) extending from the first portion into the heating chamber and terminating at a discharge end (38) within the heating chamber, a feed mechanism (40) configured and arranged to feed product into the process tube, and a bearing assembly operating between a support frame (34) and the first portion of the process tube and configured and arranged to support the process tube and transmit rotational torque to the process tube.
