ABSTRACT:
A continuous feed volumetric heating and convection oven for heating articles includes an oven body, a conveyor for moving the articles therethrough, a volumetric heating source for delivering microwave or other volumetric heating energy to the oven body, and a ventilation system for delivering a flow of heated air to the oven body. The ventilation system includes a heater and at least one damper associated with an exhaust whereby air may be partially recirculated and partially exhausted from the oven body. Microwave chokes and microwave suppression tunnels are provided for limiting the escape of volumetric heating energy such as microwave energy into the surrounding area and into the ventilation system.
