ABSTRACT:
An oven for preparing food comprising an enclosure having a conveyor received therethrough for conveying food to be prepared through the enclosure. Positioned within the enclosure and about the conveyor portion therein are duct devices for impinging heated air against the food product, a plenum adapted to the duct devices for supplying heated air to the duct devices, and an impeller assembly for recirculating the air within the enclosure for reheating and subsequent passage to the plenum and duct devices. A heating source is provided within a heating chamber on the opposite side of the plenum from the duct devices, and control components are provided for regulating the temperature of the heat source. The impeller assembly and the plenum are unique in that air drawn from the heating chamber by the impeller assembly is axially and radially urged into the plenum for substantially uniform distribution to the duct devices communicating with the plenum. The impeller assembly and the plenum also uniquely provide for the air flow to be reversed in a very short distance. Furthermore, the structure of the impeller assembly and plenum provide at various points tapering walls, which permit air to flow thereover in a non-turbulent manner, thereby eliminating dead spots or stagnant air pockets.
Further novelty of the present invention exists in the conveyor assembly wherein an adjusting mechanism is provided at one end of the conveyor frame for adjusting the slack or tension of a continuously moving wire-link belt.
