When the high-frequency alternating current goes to the coil, it will generate a certain range of magnetic fields. This
magnetic field range can generally reach the top of the glass-ceramic within 3cm height. The internal molecules
of the bottom of the pot or pan rub intensely through the induction of the magnetic field so that the vessel itself
generates thermal energy.
Compared to traditional gas stoves and electronic stoves, which use a burner or heating element to heat indirectly
and deliver the heat to the food in a radiation range, the induction cooker is better, which can reduce the wast-
age of heat energy, thereby keeping the kitchen cool. It is crucial for smaller kitchens or sites struggling with high
temperatures.
In other words, if we use an induction cooker, the heat source would be the cookware itself, it heats the food directly,
so less heat emits to the surrounding air, and cooking is faster. According to our experiments, the thermal energy
utilization rates of gas stoves, electric stoves, and induction cookers are different, respectively 40%, 74%, and 90%.
It means better temperature controllability and less cooking time with the induction. “This is a physical reaction
that happened in an instant,” says Mr. Chen, the product development manager of the Lestov factory.

As for the range of temperature, the induction cooker has a wide variation, and the boiling time is far lesser than
that of the electric stove or the gas stove. Besides, the surface of the burner remains cool, so you don’t have to
be concerned about burning your hands if you touch the surface of the burner by accident.
You can even put a paper towel between the induction burner and a boiling pan. You will find that the pan gets
hot, but the surface of the burner is as cool as usual. Because the pan will be inducted by the electromagnetic,
but the paper will not.
Advantages of Commercial Induction Cooktops:
Regarding the advantages of the induction cooker: Firstly, it is easy to clean. Since the cooktop itself is not hot,
it is easy to clean. Turn off the power first, then clean it with cleaning cream and then with a soft cleaning pad or
cloth. Secondly, the new induction cooker has time control or temperature control to prevent the food from burning
or over-cooking, and the bottom of the pot is evenly heated.
When the set time is up, it will automatically shut down, but the gas and electronic stoves have no function in this
regard. Furthermore, the induction cooker has a built-in protection system. The equipment will automatically shut
down once overheating, overvoltage or overcurrent occurs.
Through 18 years of experience and continuous innovation, Lestov commercial induction hob manufacturer has
released a series of smart induction cookers in 2020, which can not only achieve time setting and temperature
control on the same equipment but also preset and memorize several different menus. For example, for menu
number one, you can preset a value for a temperature of 180 degrees for two minutes according to food cooking
requests.
For menu number two, you can set the temperature to 100 degrees to cook for ten minutes for another dish, and
so on. Once the menus are preset on the equipment, you don’t need so many executive chefs, even an apprentice
can operate it, which greatly reduces the labor cost.
Study of different features of machine:
While induction cooking is not new, it has recently grown in popularity because the cost of this technology has
become more affordable. Induction cooktops are also safer to use than any other cooking method, are more
energy-efficient, provide precise temperature control, and complement popular kitchen designs trending today. But
in my opinion, those are only a few reasons why induction cooktops are a must-have. Check out some interesting
facts from the experts.
Pure Design:
An Elle Dιcor article, The Biggest Kitchen Design Trends for 2019, stated, “We will continue to see integrated
appliances.. Induction cooktops continue to be increasingly popular because of their seamless look. You no longer
need to see appliances sticking out everywhere anymore, and that’s the new face of luxury.”
Trending:
According to the 2019 Home Design Trends Survey done by the American Institute of Architects, induction cooking
appliances continue to be on the list of popular kitchen features and products.
