Abstract From the Canadian patent

Abstract of the Disclosure, A conveyorized microwave oven having multiple independently controlled lanes. Specifically, a plurality of conveyor belts are directed into, through, and out of the microwave cavity. The belts can be operated at different speeds so that foods requiring different microwave exposure times can be cooked simultaneously performed. Suppression tunnels surrounding the conveyor belts at the openings into and out of the cavity prevent the escape of microwave energy from the cavity.
