An impingement device (10) for preparing food product comprises an enclosure (12) having a conveyor (18) received therethrough for conveying food product through the enclosure (12). Positioned within the enclosure (12) and about the conveyor (18) portion therein are ducts (36) for impinging gas against the food product, a plenum (48) connected to the ducts (36) for supplying gas to the ducts (36), and an impeller assembly (44) for recirculating the gas within the enclosure (12). A heating source (40) or cooling source (340) is provided within a chamber (14) on the opposite side of the plenum (48) from the ducts and controls (26) are provided for regulating the temperature of the heat or cooling source. The plenum (48) is spaced inwardly from the walls of the enclosure (12) to provide return flow around the plenum.
