ABSTRACT:
A removable tray holds a product for heating in a dielectric oven. The tray comprises at least one wall defining an interior, wherein the at least one wall is made from a non-electrically conductive material, such as a polycarbonate resin having a thickness in a range of about 0.08 to 0.09 inches (about 2.03 to 2.29 mm). The at least one wall includes at least a first and a second electrode. Each of the electrodes comprises a first portion and a second portion, wherein the first portion is separated from the tray interior by a thickness of polycarbonate resin in a range of about 0.01 to 0.03 inches (about 0.25 to 0.76 mm). The first portions bracket the product, are substantially parallel to each other, and are encased within the at least one wall. Each of the second portions has an exposed area which when the tray is placed in the oven is coupled with an electromagnetic energy source to produce an electromagnetic field between the electrodes.
