Claim of US Patent No. 10,798,790

1. A microwave system for heating a plurality of articles, said system comprising:a microwave chamber configured to receive said articles;
a conveyance system for transporting said articles through said microwave chamber along a convey axis;
an upper microwave launcher configured to propagate microwave energy into said microwave chamber along a first central launch axis, wherein said upper microwave launcher is positioned above said convey line and configured to direct microwave energy downwardly toward said articles on said convey line; and
a lower microwave launcher configured to propagate microwave energy into said microwave chamber along a second central launch axis, wherein said lower microwave launcher is positioned below said convey line and configured to direct microwave energy upwardly toward said articles on said convey line,
wherein said upper and said lower microwave launchers are positioned on the opposite sides of said microwave chamber, wherein said upper microwave launcher is tilted such that a first launch tilt angle of at least 2° and not more than 15° is defined between said first central launch axis and a plane normal to said convey axis and wherein said lower microwave launcher is tilted such that a second launch tilt angle of at least 2° and not more than 15° is defined between said second central launch axis and a plane normal to said convey axis.
