Support surface for heating food articles and the method of making same

A support surface for transferring heat from a source to food articles placed adjacent said surface, said support comprising:

• a) a plurality of longitudinally extending support elements made of heat conductive material placed in side-by-side relationship to form a substantially planar heating surface, each of said support elements having at least one longitudinal passageway therethrough extending from a first to a second end thereof for carrying a heated transfer fluid,
• b) first and second header means adjacent said first and second ends, respectively, each header means having a plurality of interconnected apertures each of which is in alignment with a corresponding passageway in said support elements, and
• c) a plurality of individual tubular elements, each element having one end inserted in one of said apertures and the other end of each of said elements inserted in one of said support element passageways corresponding thereto for transferring said heated fluid from said header means to each of said support elements, each of said tubular elements having an orifice formed therein which is sized to equilibrate the flow of fluid through said corresponding passageway, each of said tubular elements further having at least one O-ring seal adjacent each end thereof which engage apertures and corresponding passageways to form a fluid tight seal therebetween.
