A microwave heating system configured to heat a plurality of articles and a process for using the same are provided. The microwave heating system includes a liquid-filled thermalization zone, a liquid-filled microwave heating zone, and a pressure lock system disposed therebetween. The pressure lock system includes a pair of locking gate valves and a pressure adjustment chamber configured to transition the articles being heated from the thermalization zone to the microwave heating zone, which may be operated at different pressures.

Pressurized heating system with enhanced pressure locks

A locking gate device suitable for selectively blocking the flow of fluid and/or articles through a pair of openings defined by two spaced-apart members is provided. The spaced-apart members may be opposing walls or flanges of two adjacent processing chambers or vessels in a pressurized heating system. The locking gate device includes a gate assembly that is movable within a gate-receiving space defined between opposed sealing surfaces of the spaced-apart members. The gate assembly comprises a pair of sealing plates and a drive member shiftable relative to the sealing plates. As the drive member is shifted between a retracted position and an extended position, a pair of bearings disposed between the sealing plates and the drive member forces the sealing plates outwardly to contact the sealing surfaces of the spaced-apart members. This substantially blocks the flow-through openings defined by one or both sealing surfaces and restricts flow therethrough.
