Abstract
A natural or LP gas-fired laminated griddle top structure providing an even distribution of heat over its cooking surface is disclosed. The griddle top includes an upper plate formed from a relatively thick iron or steel plate and a plurality of relatively thick lower plates formed from a dissimilar material having a high thermal conductivity. A thermal break is provided between adjacent lower plates and each lower plate has a channel provided therein for the receipt of a temperature sensing device. In addition, laterally extending grooves are provided in the bottom surface of the lower plates increasing the resulting heat transfer surface improving the thermal efficiency of the griddle top. One or more natural or LP gas-fired burners and associated controls are provided adjacent each lower plate permitting the entire cooking surface to be maintained at the same temperature or portions thereof to be maintained at different temperature, if desired.
