Abstract
The oven of the present invention is a low profile, dual conveyer oven including an oven cabinet, two closely spaced conveyers and an air heating and circulation system. The conveyers and the oven cabinet are adapted so that the conveyers can be easily removed from the from the front or side of the oven cabinet. The oven cabinet houses the conveyers, ducts and manifolds which all can be easily removed for cleaning or other maintenance. Each of the conveyers include separately controlled drive motors capable of driving the each of conveyers at different speeds and in different directions. The air heating and circulation system features a transverse mounted burner tube, side mounted return air ducts, a central return air opening, common shaft mounted side fed dual centrifugal fans and hot air manifolds. The hot air manifolds are fed from the rear by the dual centrifugal fans and are adapted to surround the two closely spaced conveyers and supply those closely spaced conveyers with hot cooking air within a space having a very limited vertical dimension.
