ABSTRACT:
A modular microwave tunnel oven with multiple microwave sources and controlled atmosphere for the continuous processing of food products has a cruciform shaped conductive cavity of extended length through which a conveyor belt runs for carrying food products through the oven; the conveyor belt and other structure within the cavity are fabricated of non-toxic, heat resistant materials that are transparent to the microwave radiation and have inner surfaces that contact the food products that can be easily cleaned; one side of the cavity formed by one or more hinged doors opens completely along the extended length making access for changing the conveyor belt and/or cleaning the oven unobstructed; and microwave energy is launched into the cavity above and below the conveyor belt; whereby the microwave energy fields tend to be greater along the middle of the conveyor belt than along the edges thereof.
