Convection oven with circulated air filtration means

摘要

A convection oven with a filtration system for recirculated convection gas. The oven includes an interior chamber, a product support in the interior chamber and a blower in fluid communication with at least one duct (preferably a plurality) for circulating air into the interior chamber. The duct has a plurality of orifices positioned to direct temperature controlled gas toward the product support. At least one perforated filter plate with a plurality of bends is disposed within the interior chamber separating the interior chamber into a cooking chamber and an air return chamber. In leu of the filter plate the filtration system includes a plurality of louvers disposed in the interior chamber separating the interior chamber into a cooking chamber and an air return chamber, the louvers being downwardly inclined toward the cooking chamber and positioned such that the temperature controlled gas passes through the louvers before returning to the blower for recirculation into the air delivery duct. A catalytic converter is also provided in the return air path to capture and eliminate entrained food particles from the circulating gas.
