(2)700w to 1600w medium fire, about 170℃-200℃.
(3) 1700w to 2 100w fire, about 280℃-300℃.
Induction cookers are divided into civil induction cookers and commercial induction cooker according to the places of use. According to the purpose, it is divided into induction cooker, professional hot pot induction cooker, cafeteria insulation stove, kitchen soup stove and kitchen cooking stove.
According to the power, it is divided into induction cookers, low-power induction cookers (below 800W), ordinary-power induction cookers (1000W-2500W) and high-power induction cookers (3KW-35KW).
According to the way of use or installation, it is divided into embedded (sinking) induction cooker, desktop induction cooker and floor induction cooker. In addition, some professional induction cookers are also named after the number, shape and configuration of burners.
Extended data:
The surface of the induction cooker is a heat-resistant ceramic plate. Alternating current generates a magnetic field through a coil under a ceramic plate. When the magnetic lines of force in the magnetic field pass through the bottom of an iron pan, a stainless steel pot and the like. , produce vortex, so that the bottom of the pot quickly heats up, thus achieving the purpose of heating food.
The cooktop is a high-strength and impact-resistant ceramic flat plate (crystal glass). A high-frequency induction heating coil (i.e., an excitation coil), a high-frequency power conversion device and a corresponding control system are installed at the lower side of the stove, and a flat-bottomed frying pan is placed above the stove.
Its working process is as follows: current and voltage are converted into direct current by rectifier, and then converted into high-frequency alternating current exceeding audio frequency by high-frequency power conversion device, and the high-frequency alternating current is added to the flat hollow spiral induction heating coil, thus generating a high-frequency alternating magnetic field, and its magnetic lines pass through the ceramic platen of the furnace and act on the metal pot.
Due to electromagnetic induction, there is a strong eddy current in the pot. When the vortex flows against the internal resistance of the pot, the conversion from electric energy to heat energy is completed, and the generated Joule heat is the heat source of cooking.
The material of the pot must be iron or alloy steel, and its high permeability can enhance the magnetic induction, thus greatly enhancing the eddy current electric field and eddy current thermal power. Cookware made of other materials will start automatic protection due to abnormal load of induction cooker caused by too large or too small material resistivity, and it will not work normally.
At the same time, because iron fully absorbs the magnetic field, it has a very good shielding effect and reduces a lot of magnetic radiation, so the iron pot is safer than any other cooker. In addition, iron is an essential element that the human body needs to ingest for a long time, but the human body can only absorb divalent iron. Iron pot cooking contains trivalent iron, but it reduces vitamins in the body and can convert trivalent iron into divalent iron, which is easy to absorb.
