ABSTRACT:
A dielectric oven for heating a product with a tray includes a housing having an access, wherein the housing defines a heating cavity. The oven includes an oven liner which substantially conforms to the interior shape of the heating cavity and forms a liner cavity within the heating cavity. The liner is made from a non-electrically conductive material which may have a low dielectric constant, a low dielectric loss tangent, and a melting point of at least about 225.degree. F. (107.degree. C.). The liner forms a vaportight boundary between the liner cavity and the heating cavity. The liner material may be a thermoplastic resin selected from the group consisting of polysulphone, polyester, and polycarbonate resins. The liner material may be reinforced with, for example, glass fibers, such as in fiberglass reinforced polyester resin. The housing and the liner may have at least one air intake port and at least one exhaust port. At least a pair of contacts may project into the interior of the oven liner. An electromagnetic energy source is coupled to and supplies current to each of the contacts. The oven also includes at least first and second electrodes each of which are coupled to one of the contacts and the electrodes bracket the product when placed in the oven for heating.
