Ih in the non-stick pan is induction heating. The principle of electromagnetic heating is that the components of electronic circuit board generate alternating magnetic field. When an iron-containing container is placed on it, alternating magnetic lines of force are cut on the surface of the container, and alternating current (eddy current) is generated in the metal part at the bottom of the container. Vortex makes the carriers at the bottom of the container move irregularly at high speed, and the carriers collide with atoms to generate heat energy. So as to achieve the effect of heating articles.

Because the iron container itself generates heat, the heat conversion rate is particularly high, up to 95%, which is a direct heating method. Induction cookers, induction cookers and electromagnetic heating rice cookers all adopt electromagnetic heating technology.

Extended data

Stainless steel pot is characterized by poor heat dissipation, easy to produce hot spots and scorch food. Stainless steel pot pot is heavy, difficult to clean, and easy to smoke when used for a long time. Iron enamel pot has poor heat dissipation and is easy to paste the bottom of the pot. This kind of pot is not easy to clean, and its surface is easy to be damaged, which leads to the rust of iron substrate.

The heat distribution of iron pot is not good, which is easy to produce hot spots and burn food. The pot is heavy, difficult to clean, easy to rust, and has a large oil smoke after being used for a long time.

The non-stick pan overcomes all the shortcomings of the traditional pan mentioned above, and it is easy to clean and can be cleaned with a light touch. Non-stick pan can easily fry food, does not stick to the bottom, can minimize the use of oil, make the kitchen clean, less oil smoke.

Non-stick pan products can be divided into boiling pan, frying pan, frying pan and milk pan according to different functions, and can be divided into one-layer system, two-layer system and three-layer system pan according to the non-stick coating system on the inner surface. Single-layer system refers to a non-stick layer composed of a single coating; Two-layer system refers to a non-stick layer composed of two kinds of coatings: the bottom layer and the top layer; Three-layer system refers to a non-stick layer composed of bottom layer, middle layer and surface layer. According to the external surface treatment of products, it can be divided into enamel, high temperature resistant paint and polished non-stick pan.
