ABSTRACT:
A system wherein air moves in a primary path over materials to be processed and wherein at least a portion of the air moves in a supplemental path for processing the air. Such system comprises a primary chamber of air for receiving material to be processed by a flow of air. The primary chamber has an air supply opening and an air return opening. A secondary chamber is provided for receiving air to be processed in a flow of air. The secondary chamber has an air supply opening and an air return opening. The air supply openings of the primary chamber are in flow communication with the air return opening of the secondary chamber and with the air return opening of the primary chamber being in flow communication with the air supply opening of the secondary chamber. The secondary chamber has a first path and a second path. A heat exchanger extends between the first path and the second path. An initial thermal member is located in the first path and is adapted to receive air from the heat exchanger and to initially process it for allowing passage of such initially processed air into the secondary path. A subsequent thermal member is located in the second path and is adapted to receive air from the heat exchanger and to subsequently process it and for allowing passage of such subsequently processed air into the oven.
