Abstract:
1. A multi-zone griddle comprising: an upper continuous layer of metal adapted for cooking a food product thereon, said upper continuous layer of metal having a front edge, a rear edge, a left side edge and a right side edge and being of a predetermined length; a first lower layer of metal having a front edge, a rear edge and a left side edge that are substantially aligned with the front edge, rear edge and left side edge of the upper continuous layer of metal, said first lower layer being of a predetermined length that is less than the predetermined length of said upper continuous layer of metal and being displaced a predetermined distance relative to said upper continuous layer of metal to form a space therebetween; a second lower layer of metal having a front edge, a rear edge and a right side edge that are substantially aligned with the front edge, rear edge and right side edge of the upper continuous layer of metal, said second lower layer being of a predetermined length that is less than the predetermined length of said upper continuous layer of metal and being displaced a predetermined distance relative to said upper continuous layer of metal to form a space therebetween; the predetermined length of said first lower layer and the predetermined length of said second lower layer being substantially equal to the predetermined length of the upper continuous layer of metal with a space being formed between the first lower layer and the second lower layer; and at least one serpentine passageway being formed in the space between the first lower layer of metal and the upper continuous layer of metal, said at least one serpentine passageway being adapted to be connected to a source of heated fluid for providing heat to a portion of said upper continuous layer of metal that corresponds to the position adjacent to the at least one serpentine passageway; wherein supplying a heated fluid to said at least one serpentine passageway permits said portion of said upper continuous layer of metal that corresponds to said at least one serpentine passageway to be held at a first predetermined temperature, whereas a portion of said upper continuous layer of metal that is displace laterally relative to the portion corresponding to said at least one serpentine passageway is maintained at a second predetermined temperature.
