The induction cooker system uses a coil disk to generate a low-frequency (20-25KHZ) alternating magnetic field under the action of a control circuit. After passing through a magnetic (iron) pot, a large amount of dense eddy currents are generated, and the induced current is converted into heat to heat food, resulting in high energy efficiency. Use flat bottomed pans made of iron, special stainless steel, or iron baked enamel, with a pot bottom diameter of 12-26 centimeters. The induction cooker is equipped with a temperature controller, which can prevent overheating, save electricity and ensure safety.
advantage
1. Fast heating speed - Induction cookers can raise the temperature at the bottom of the pot to over 300 degrees Celsius within 15 seconds, much faster than oil and gas stoves, greatly saving cooking time and improving cooking speed.
2. Energy saving and environmental protection - Induction cookers have no open flames and generate heat on their own, reducing heat transfer losses. As a result, their thermal efficiency can reach over 80% to 92%, and there are no exhaust emissions or noise, greatly improving the kitchen environment.
3. Multifunctional - Induction cookers are versatile in stir frying, steaming, boiling, stewing, and rinsing. In Shanghai, new families of three usually use induction cookers, which have basically replaced gas stoves, and pipeline gas mainly uses showers.
4. Easy to clean - Induction cookers have no fuel residue or exhaust pollution, so pots and stoves are very easy to clean, which is unimaginable in other stoves.
5. High safety - Induction cookers are not prone to leaks or open flames like gas, making them significantly safer than other stoves. Especially, it is equipped with multiple safety protection measures, including furnace tilting power-off, timeout power-off, dry burning alarm, overcurrent, overvoltage, undervoltage protection, improper use automatic shutdown, etc. Even if the soup overflows sometimes, there is no danger of gas stove stalling and running out, making it worry free to use.
6. Easy to use - The "one click operation" indicator of the civilian induction cooker is very user-friendly, which can be seen by the elderly and children at a glance. In addition, the stove itself weighs only a few pounds, so it is not a problem to take it anywhere, as long as there is a power source, it can be used. For migrant workers with small living spaces, take it out from under the bed and put it back in after use.
7. Economical - Induction cookers are a major electricity consumer, but due to their fast heating and relatively low electricity prices, they are cheaper in cost compared to gas and natural gas. In addition, the lowest price for a 1600W induction cooker is only over 100 yuan, and the cookware is also included.
8. Reduce investment - Commercial induction cookers require much less kitchen space than traditional stoves, as there is no combustion exhaust gas. Therefore, the investment in exhaust equipment is reduced, and the construction and supporting costs of gas pipelines are exempted.
9. Accurate temperature control - Induction cookers can precisely control cooking temperature, which not only saves energy but also ensures the deliciousness of food, and is important for promoting the production standards of Chinese cuisine.
10. Compared to the single function of a microwave oven, an induction cooker is versatile in steaming, boiling, frying, stir frying, and deep frying. It can also be used as a hot pot or commercial hot pot, with adjustable firepower and automatic insulation.
shortcoming
1. The temperature rise is particularly fast, and preparation work should be done before starting the furnace, otherwise it is easy to cause dry burning of the empty pot, shortening the service life of the cookware and induction cooker;
2. The probability of electromagnetic stove failure is higher than that of traditional stoves, and maintenance is more complicated. If a failure occurs, the lack of a backup stove will affect operations;
3. The power of an induction cooker is closely related to the cookware, so there are high requirements for the cookware and poor universality of the cookware;
4. When the induction cooker is working, there is a significant temperature difference between the bottom and the body of the pot. If the bottom is not turned over in time during cooking, it is easy to burn;
5. Civilian ordinary induction cookers are usually flat plates that require the use of a flat bottomed pan, while shallow bottomed pans are not as convenient for stir frying as traditional ones;
6. The power and temperature displayed on the induction cooker panel are pre-set by the program and may differ significantly from the actual power and temperature;
7. Induction cookers without automatic shutdown function for soup overflow yet
8. Induction cookers do not have open flames, making it difficult for ordinary people to intuitively grasp the temperature. Professional chefs need a long time to adapt from open flames to induction cookers.
9. The magnetic field generated by the induction cooker cannot be fully absorbed by the cookware, and some of the magnetic field leaks out from around the cookware, forming electromagnetic radiation.
