Grilling surface

摘要

A grilling component employed to grill food items includes a grilling surface made of a material having a low constant of thermal expansion. In one example, the grilling surface is made of Invar(TM). Invar(TM) is a metal allow comprised of Iron and 36% Nickel, and may include other trace elements. Invar has a low constant of thermal expansion and therefore moves and expands very little when heated. The grilling surface further includes a non-stick coating, such as Teflon(TM). The grilling surface can also be a conveyor belt which travels over a heater.
