Abstract: A reverse air flow oven for symmetrically heating product inserted within a heating chamber in the oven. The oven includes duct work configured symmetrically about the heating chamber, and a fan provides continuous circulation through the duct work and the heating chamber. The duct work also includes a pair of doors having complimentary configurations so that in one configuration, the air flow is in a first direction, and in the complimentary configuration, the doors cause air flow in the opposite direction. Further, a perforated plate regulates and equalizes air flow across the heating chamber and includes valve plates for controlling a build up of static pressure within the heating chamber.
