General principles of operation of induction cookers
Induction hobs are a perfectly smooth surface made of glass ceramics or other composite material that does not have magnetic or electrical properties. When an induction cooker operates, a magnetic field is created, which leads to heating of the cookware. The most important feature of this type of cooker is the heating principle, which generates a magnetic field.
For these purposes, special coils are used, made of metals with good electrical conductivity. As the oscillation frequency increases, which can vary from 20 to 100 kHz, the electromagnetic field rises above the surface of the hob. If there are materials with magnetic properties on the burner at this time, the process of exciting an electric current occurs.
As current flows, the metal from which the cookware is made resists the movement of electrons, which leads to an increase in temperature. Thus, the stove always remains cold, and an increase in temperature is observed only in cookware that should have ferromagnetic properties.
The process of electromagnetic induction was discovered by Michael Faraday in 1831. The use of this physical phenomenon in the creation of slabs made it possible to obtain products with increased efficiency, reduced energy consumption, and safety. Inside the burner there is a coil made of metal that has magnetic properties. The main disadvantage of this technology is its high price compared to traditional options. It is also very important when using induction to use the correct cookware to achieve the desired temperature rise.
Geyser "Turk" for induction cooker
More precisely, it is called a geyser-type coffee maker. In recent years, these models have become increasingly popular. Induction heating in such structures is recognized as almost the most effective and safe heat transfer technology.
This coffee maker is equipped with a thickened bottom made of a special ferroalloy (anodized aluminum or stainless steel). Installing it on an induction hob generates a magnetic field, which, penetrating the magnetic material, creates an eddy electric current that is converted into heat. It penetrates the liquid that is in the coffee maker and does not go beyond the boundaries of the dishes.
This principle of heating and simmering coffee is perfect for brewing sophisticated espresso, revealing a rich bouquet of coffee flavors.
What cookware is suitable for an induction cooker?
When choosing an induction panel, you need to pay special attention to the cookware, since not every household item can be used for cooking. It is often necessary to completely reconsider existing items. This also applies to coffee turks for an induction cooker, which has general requirements. The main feature of induction is that only the metal area is heated, while the rest of the burner remains cold. The most important quality that cookware should have is the presence of ferromagnetic properties at the bottom. Simply put, it is necessary that the selected item of utensil can conduct electromagnetic waves and be subjected to magnetic induction for subsequent heating. Many manufacturers produce special cookware that has a number of distinctive features:
- the presence of a disk in the center, the purpose of which is the accumulation and distribution of thermal energy;
- endowing the bottom with ferromagnetic properties;
- a perfectly smooth bottom, with a metal thickness of at least 2 mm.
It is important that the bottom of the cezve covers a sufficient area of the cooking surface for its operation. It is also important to comply with one more requirement - the diameter of the bottom of the pot for a glass-ceramic stove must be at least 30% of the burner area. Otherwise, the latter simply will not turn on.
To determine whether the selected cookware is suitable for panels using induction technology, you can pay attention to the presence of a special sign in the form of an elongated upward spiral and the inscription “induction”.
Dimensions and materials of induction Turks
To buy the right coffee pot for your induction cooker, you should take into account what it is made of. You can immediately note the materials that are not used in the manufacture of real cezves intended for this type of panel. Coffee connoisseurs consider ceramics or clay to be the best material for Turkish coffee, since it has the unique properties of preserving the aroma. These include copper, aluminum and ceramics. In their pure form, these materials do not have magnetic properties. Cezves can be used in this case only if they have a special bottom endowed with ferromagnetic properties.
Steel is considered the optimal Turkish material for an electric induction cooker. But true connoisseurs believe that clay is the ideal material for the item needed to make coffee. It is this that is capable of preserving the aroma due to its porous structure.
FOR YOUR INFORMATION ! You can use clay cezves, but it is very important that the bottom has a special magnetic insert to ensure the required heating. For induction panels, the stainless steel option is most often purchased. The second important selection criterion is the size of the cezve. The most important thing is to ensure the correct diameter. It must be no less than 30% of the total diameter of the burner, otherwise it simply will not turn on.
Coffee connoisseurs also pay attention to the volume of the cezve. Usually on store shelves you can find options that offer to brew from 0.15 to 0.5 liters of drink. In the brewing process, the principle “less is better” applies.
That is why it is recommended to choose not the largest models. But at the same time, the smallest options do not satisfy the requirement of covering the burner area to activate the magnetic field, so they will not heat up.
IMPORTANT!
One of the selection criteria is the handle, which should be long enough, fit comfortably in the hand and not heat up during the cooking process. The handle should be long and not hot so as not to burn your hands
Adapter for induction cooker - buy to brew coffee in any Turk
If you really want to enjoy the true aroma of the finished drink and use a clay or copper cezve, there is the possibility of purchasing a special device called an adapter. Using an induction disc or adapter will make it possible to use any material. This is a simple metal disc that is placed on the burner. The stove considers it an example of “correct” cookware, which leads to heating. The adapter can be used to place utensils made of any material, in particular cezves made of ceramic or copper.
When using an induction disc, the diameter of the bottom does not matter. When purchasing an adapter, it is very important to choose models that have ferromagnetic properties. Poor-quality products can cause premature wear of the stove, and will also not allow you to prepare tasty and aromatic coffee. The presence of a handle on the adapter increases the comfort of its use. Induction discs consist of several metal plates, between which there is a magnetic layer, due to which it is possible to achieve uniform heating of the cookware.
It would be optimal to purchase a disk with a handle, which will simplify the process of use. The handles are made of materials that do not heat up, which makes it possible to operate without tacks.
FOR YOUR INFORMATION ! If the adapter is purchased exclusively for a coffee turk for an induction cooker, it is better to buy a small model so as not to clutter up the kitchen space with unnecessary accessories.
Why do you need a special Turk for an induction hob?
The features of the induction surface require special cookware not only for coffee. You'll have to take care of the pots and pans too.
Being an electrical appliance, an induction cooker is noticeably different from electric ones. There are no visible heating coils on it. Just a flat, smooth slab. However, she will both cook and fry. But heating does not occur over the entire surface, but in certain places where there is an inductance coil under the burners.
Reference. To operate a surface operating on the principle of a transformer, two windings are needed. The role of the primary is played by the induction coil, the role of the secondary goes to the dishes.
That is why you need to take special care of her.
Which Turk for an induction cooker is best to buy, depending on the manufacturer
When choosing a specific model, you need to take into account the manufacturer, since there are models from several companies on the market. They all have their positive and negative sides. Gipfel company presents the widest range of products
Turks for induction cooker Gipfel, Korkmaz, Erringen
In fact, among the main brands producing special Turks for induction devices, 4 manufacturers predominate. It is their products that are considered the best and are popular among gourmets:
- Gipfel . A brand that produces a wide range of Turks for brewing coffee on induction panels. The model range is represented by the largest variety of volumes - 390, 500 and 700 ml. All cezves of this brand are made of polished steel, have a wide neck and a fairly thick bottom (from 6 to 8 mm).
- Korkmaz . This manufacturer specializes in producing Turkish sets of different volumes. Just one set includes three pieces, the smallest of which has a capacity of only 20 ml, and the largest - 400 ml. One of the features is the presence of a comfortable handle with silicone inserts.
- Erringen . A company that also produces stainless steel cezves. The company does not offer the widest range of models. It includes 360 and 720 ml models. Among the distinctive features, comfortable handles should be noted.
Under the Tima brand, copper cezves with a narrow neck are produced to obtain a rich taste
Copper cezves Tima
The Tima brand stands out, as it is the only manufacturer on the Turkish market that produces copper cezves. Their bottom is endowed with ferromagnetic properties specifically for heating.
And the copper alloy ensures fast and uniform heating, which is very important when preparing an invigorating drink. Another advantage of copper products is the presence of a narrow neck, which ensures a rich taste.
FOR YOUR INFORMATION ! Copper has thermal conductivity 10 times better than steel and 2 times better than aluminum.
The nuances of choosing a Turk for an induction cooker
It's not just ceramic or copper coffee pots that have problems. Even those Turks that contain ferromagnetic alloys may not be suitable. They often have a bottom diameter that is too small. In order for the burner to heat up, the container placed on it must be no less than the value specified by the manufacturer. Due to the small volumes, the stove “does not notice” the coffee makers, which are taken from a set of pans quite suitable for an induction stove. If they are 8-12 cm, these are already critical indicators of the bottom diameter for the technology that is fashionable these days.
Special adapter disks solve this problem. The disc itself heats up and transfers heat to the coffee container.
With such an additional device, all other coffee pots, made of any material, will work.
Another significant plus: the ferromagnetic disk makes it possible to use Turks with a narrow neck. This plays an important role for gourmets: preparing coffee with foam and its aroma requires a classic cezve shape.
How to brew coffee in an induction pot
To prepare the perfect drink, you need to follow the brewing technology. In normal mode, the induction cooker operates at low power (ranging from 45 to 50%). In this case, heating is carried out in pulse mode, which is completely unsuitable for coffee, which requires a uniform temperature with a gradual increase. That is why to prepare a drink on an induction panel you need to set the power in the range from 70 to 80%. After foam has formed, be sure to remove the cezve from the stove. A small amount of ground coffee is poured into the Turk. Usually 30-40 grams is enough. Next, add a pinch of salt and sugar (optional). The powder is poured with cold water and gradually brought to a boil.
When foam appears, the cezve should be removed from the stove, allowed to settle and placed back on the burner. Ideally, repeat this procedure 5 times to fully develop the aroma and taste. After completion, it is recommended to let the finished mixture stand for a few seconds to completely saturate the drink with aroma, after which the coffee can be drunk.
FOR YOUR INFORMATION ! You should not leave the finished coffee for a long time, otherwise the oils may simply erode and the aroma will be lost.
Upon completion of brewing, it is advisable to pour the coffee into cups to prevent the oils from evaporating. If you have an induction cooker, you can indulge in freshly brewed coffee. In order to be able to enjoy the drink, you should purchase special dishes or simply buy an adapter. Once again, you can learn the intricacies of choosing a Turk for induction from the presented video.
