induction cookers use the principle of electromagnetic induction heating to heat food, which can be divided into two types: commercial and domestic. If you run a restaurant, you should choose commercial induction cooker instead of home. The following is the correct use of induction cooker that I have compiled, hoping to help everyone.
commercial induction cooker
the commercial induction cooker is mainly composed of a cooker surface, a shell, a pot body, an excitation coil, an excitation core, a control element and the like. The cooktop is generally made of glass-ceramics, which has good impact resistance and insulation. There is a disc-shaped high-frequency induction heating coil and a control circuit board under the panel.
At work, it is very convenient for commercial induction cookers to automatically control the whole cooking process by using computers. Firstly, the current is converted into DC by rectifier circuit. The DC voltage is converted into a high frequency current of 21-51kHz through a circuit composed of induction heating coils, high-power transistors, capacitors and other elements. According to the principle of electromagnetic induction, a high-frequency alternating magnetic field is formed around the electrified induction heating coil, resulting in a strong magnetic field line. The magnetic field lines pass through the glass-ceramic table of the induction cooker, and a large number of eddy currents are generated at the bottom of the cooker, thus heating the cooker.
in order to increase the eddy current, you must use a pan that matches the countertop of the induction cooker, not a pointed pot, or a container that has a gap with the induction cooker. It has the advantages of high thermal efficiency, accurate temperature control and small thermal inertia, and can immediately cut off the magnetic field after power failure and no longer generate heat. Moreover, it has good safety, no fire, no fire and other dangers. Therefore, it is safe and convenient to use and can be purchased with confidence.
how to choose a commercial induction cooker
when buying a commercial induction cooker, we should pay attention to the details, otherwise buying a fake will affect the future use process. What are the skills for choosing commercial induction cookers? The following methods are quick to get:
1. Choose the right type: At present, most of the induction cookers sold in the market, whether imported or made in China, are high-frequency induction cookers, and only a few are low-frequency induction cookers. Because compared with low-frequency induction cooker, high-frequency induction cooker is more suitable for home use, with the characteristics of safe use, easy cleaning and light weight, which is widely favored by consumers.
2. Comparative price: Under the condition of the same power, we can choose a more cost-effective induction cooker through price comparison.
3. Check the cooktop: If the cooktop is made of glass-ceramics, it can withstand the cold shock at 611 degrees. When checking, although it is not necessary to flush with cold water, it is also necessary to see whether the kitchen surface is smooth, free from cracks and stains. If it is made of tempered glass, it will crack in case of cold water impact. When purchasing, try not to choose this material.
4. Check the parts: When purchasing, also check whether the parts of the induction cooker are complete, and it is required that there is no abnormality during installation. When checking, you can hold the induction cooker in your hand, shake it a few times, and judge the looseness of internal parts by hand feeling.
5. power-on test: test whether the protection function of the induction cooker is normal and whether the fan air volume is large enough. It is suggested to add water to the pot to minimize the power and test the heating effect.
how to use the commercial induction cooker
when using the commercial induction cooker, there are many things that need to be paid attention to. If you don't pay attention, it will lead to failure, which will directly affect the service life. What are the precautions for using commercial induction cookers? The following points are quick to mark:
1. The cookware placed on the induction cooker should be good in magnetic conductivity, so that the magnetic energy can be better converted into heat energy after being electrified.
2. If cooking food, first heat the food with high power, and then switch to low power. Pay attention to adding water to the pot, and the bottom of the pot should be flat.
3. If the food is fried with strong firepower, it is recommended to use high-power gear to heat it, and the heat is concentrated at the bottom, and the food is best placed in the middle.
4. When using, put away the cooker before starting the induction cooker. After cooking, cut off the power first, and then remove the cooker. Do not burn it empty.
5. Don't let nails and other foreign objects extend into the exhaust port, and don't put foreign objects on the panel of the induction cooker to avoid abnormal situations.
6. The distance between the induction cooker and the wall should be more than 11 cm, and don't get too close, so as not to affect the heat dissipation during its operation.
Is the radiation of commercial induction cookers large?
Does the power of commercial induction cookers mean high radiation? If you work in this environment, what will be the impact? I believe that some people will have this kind of worry, and today Mom.com will answer it.
The commercial induction cooker has radiation, but it is not an "invisible killer" because its radiation is upward, mostly distributed at the bottom of the cooker. A small amount of radiation is leaked, but it has little impact on human body, so it will not have much impact on health if used in the right way.
However, there are a lot of commercial induction cookers in the market, so it is difficult to guarantee that some merchants will shoddy. Therefore, when buying, you must identify the merchants. Otherwise, the purchased products are unqualified, and the radiation may be great. Because the radiation of induction cooker is closely related to the quality and power of the product. Commercial induction cookers are already high-power induction cookers. If we don't pay attention to quality, it will really have an impact.
In use, in order to prevent the leaked radiation from affecting people's health, some radiation protection measures must be taken. First of all, keep a certain distance from the induction cooker, and don't be too close to the bottom of the pot when using it, because the radiation of the induction cooker is mostly located at the bottom of the pot. Secondly, wear radiation protection clothing to prevent radiation from directly penetrating the human body and damaging people's health. Finally, check the induction cooker regularly and do a good job of maintenance to avoid abnormal situations.
Precautions for troubleshooting of commercial induction cookers
If the bought commercial induction cookers break down due to improper use or problems of the machine itself, they should be repaired as much as possible. However, instead of repairing it yourself, we need to find professional maintenance personnel, otherwise, it will cost a lot of money to replace it if it is broken. How to repair the commercial induction cooker? The following are the maintenance precautions for commercial induction cookers:
1. The induction cooker is not heated
If the induction cooker is not heated, the simplest solution is to replace the cooker; If the reason is short circuit of induction cooker sensor, replace the sensor; If the current is too strong, it can be suspended for a period of time, and then restarted when the current returns to normal.
2. The indicator light doesn't light up
If the indicator light turns red, but it doesn't turn green after pressing the heating key, there are two reasons. One is that there is something wrong with the indicator light circuit, and the other is that there is no high-frequency current on the excitation coil at the bottom of the pot. When overhauling, first use a multimeter to check whether the excitation coil at the bottom of the pot is open, and if so, replace the excitation coil. If not, replace the indicator light.
3. The induction cooker is noisy.
