Abstract

A commercial or institutional oven with two separate oven compartments, individually controllable as to temperature. The oven compartments are ported and fan-vented for providing even distribution of heat, smoke and steam, as applicable, while minimizing the expulsion of such cooking elements from the oven compartments. The porting and exhast system are shared by the two oven compartments in avoiding duplication of components. The exhaust system induces ventilation of the oven compartments through utilization of the venturi effect rather than through direct suction by way of a direct mechanical connection between the fan and each oven compartment's exhaust port. The design of the exhaust system permits use of a general purpose fan, as opposed to one designed for high temperature use.
