In the catering industry, induction cookers are already a common type of kitchen equipment, and there are many types of induction cookers now. So today, SHINELONG editor will show you what a concave induction cooker is. What is a concave induction cooker? The concave induction cooker uses the principle of electromagnetic induction to heat food. The surface of the induction cooker is a heat-resistant microcrystalline panel. The alternating current passes through the coil under the microcrystalline panel to generate a magnetic field. When the magnetic lines of force in the magnetic field pass through the bottom of the iron pot, stainless steel pot, etc., eddy currents are generated, causing the bottom of the pot to heat up quickly, achieving the purpose of heating food. Advantages of concave induction cookers: Compared with flat induction cookers, concave induction cookers have a larger furnace surface wrapped around the bottom of the pot, which is fully compatible with traditional woks, greatly increasing the heating area of the furnace surface, and increasing the electromagnetic induction area of the furnace surface wok, so that the cooking is heated more evenly. While retaining the high thermal efficiency conversion of electromagnetic, it also takes into account people's cooking habits. Disadvantages of concave induction cookers: Compared with flat induction cookers, concave induction cookers are only compatible with concave pots and cannot use flat-bottomed pots. Concave induction cookers are more suitable for cooking, while flat induction cookers are more suitable for stewing. The black crystal of the concave induction cooker surface is more expensive and the manufacturing process is more difficult. Once damaged, it can only be replaced by the manufacturer. The pot diameters of the concave induction cookers designed by different manufacturers are different, and the compatibility is also different. It is recommended to give priority to big brands when choosing concave induction cookers. Such big brands will have better compatibility with various pots on the market. The above is a summary of what a concave induction cooker is and its advantages and disadvantages. The concave induction cooker is suitable for making food such as stir-frying, and when we buy an induction cooker, we should consider our own usage needs and then make a purchase. Pay attention to SHINELONG commercial kitchen equipment, and the editor will share knowledge about commercial kitchen equipment from time to time.
