Coatingless non-stick pan

Abstract

The present application discloses a coatingless non-stick pan and relates to the field of non-stick pans. The coatingless non-stick pan comprises a pan body, wherein a side of the pan body facing away from a heat source upon operation is formed with a plurality of protrusions, and the side of the pan body facing away from the heat source upon operation is formed with a plurality of blind holes obtained by photo etching, a depth of the blind holes is less than 400 microns, a diameter of the blind holes is less than 300 microns, a protruding height of the protrusions is less than 500 microns, and a distance of the blind holes from the protrusions closest thereto is less than 50,000 microns. In the present application, the protrusions are disposed on a working surface so that the protrusions may also form holes with a larger diameter than that of the blind holes, so that hot air is generated between the protrusions. The blind holes may contain edible oil, and even in the absence of oil, hot air is generated in the blind holes. During the cooking process, the protrusions and the blind holes may cooperate with one another to generate oil vapor or hot air to hold the food up so that a frictional force of the food on an inner surface of the pan body is greatly reduced and the non-stick effect is better.
