ABSTRACT:
A fast heating, highly efficient griddle with interchangeable griddle plates including magnetically permeable materials having Curie temperatures which may be the same or different to provide different cooking temperatures is provided. The plates are formed as a balanced composite structure which mitigates bending when the magnetically permeable materials are heated to their Curie temperatures. Induction coils provide sufficient energy to heat the plates to their effective Curie temperatures in the presence of loads and maintain a uniform cooking temperature across the griddle plate to within less than one inch of the plate edges. The plates may be placed in an enhanced idle condition at cooking temperature by placing a cover over the plates or region of a plate not in use. Increased efficiency is achieved due to an insulator blanket placed between the griddle plates and coils.
