Method of making low-fat non-stick frying device

摘要

An improved one-sided embossing process for manufacturing low-fat non-stick frying cookware is provided. The process provides a textured cooking surface free of sharp edges which increases the useful life of a non,stick coating applied thereto. The embossed cooking surface of the resulting frying device comprises a series of wave-like grooves embossed in the surface of the pan. The wave-like pattern of each groove is one-half G cycle out of phase with its neighboring adjacent grooves to form an alternating pattern of outwardly extending lands and inwardly extending roots. A raised portion or elevated surface is provided on the cooking surface disposed between the outwardly extending lands. The elevated surface is the primary cooking surface and is further the location of the inevitable initial wearing of the non-stick material. The remaining non-stick material, disposed in the grooves and between the roots is not subject to abrasive action and wears at a substantially slower rate. The raised portions or elevated cooking surfaces disposed between the lands comprise less than 30 percent of the upper cooking surface and therefore less than 30 percent of the nonstick coating disposed on the upper cooking surface is exposed to the abrasive action of cooking utensils or cleaning utensils.
