Apparatus for heating food articles

An apparatus for transferring heat to food articles contained on trays within a chamber comprising:

• (a) a chamber having a plurality of vertically upstanding spaced-apart side walls and adjoining top and bottom walls, and at least one closure member permitting access of said trays to said chamber,
• (b) a plurality of vertically spaced-apart support means between said side walls, each of said support means having a flat upper surface member for receiving one of said tray adjacent thereto, a front side member, a rear side member adjacent one of said side walls, said rear side member having an outlet formed therein, and a lower surface member tapered toward said outlet in said rear side member, said upper and lower surface members and said side members forming a fluid tight enclosure,
• (c) thermostatically controlled fluid vapor generating means, and
• (d) conduit means extending between said rear side members and being adjacent one of said side walls for interconnecting the outlet of each of said support means to said fluid vapor generating means, said generating means supplying fluid vapor through said conduit means to said enclosure of each of said support means for heating said food articles, said conduit means serving to both transmit said fluid vapor to each of said support means and return condensate fluid back to said fluid vapor generating means;
• said support means, said conduit means and said fluid vapor generating means being sealed to the atmosphere to prevent dissipation of said condensate fluid.
