Every year, household appliances are becoming more and moremore "smart" and modern - there are new electronic devices and devices that can cook tasty and healthy food in the shortest possible time. One of such devices are induction cookers. Pros and cons of these devices we will consider in our today's article.
Appearance in the world market
This technique is the youngest in the backgroundTheir brethren, as it was invented later than all the rest. Several years ago, only two types of plates could be purchased in stores - gas or electric. However, in recent years more and more sellers have been offering induction cookers.
Characteristic
To find out more about this stove, we'll talkabout the algorithm of its operation. The principle of the induction plate is as follows. The source of heat (as a rule, it is a hot iron burner or open fire) heats the dishes, which, in turn, transfers energy to products located on its surface. If this is the smoking of fish or the preparation of a shish kebab (by the way, even an induction cooker can handle this work), then the process of heat transfer takes place without such an "intermediary" as dishes, that is, all energy is directly supplied from the source to the product.
Burners
Separate attention should be burners.Outwardly, they can only be determined from the outlines on the glass ceramic surface. Unlike gas stoves, these burners do not occupy "extra" space at all and quite organically fit into the interior of the kitchen. Agree, the design of such a hob is very modern:
The main element that conducts heat to theburners, is a coil. Without it, the cooker simply will not heat food (and generally cease to work). This element is located under each burner, which is on the hob. These coils are subjected to a high-frequency current of 30-60 kHz. By their design, they are more reminiscent of the primary winding of the transformer. But here we should note one point. To generate induction currents, it is not enough to have only the primary winding.
How then does heating occur?
It's very simple - if the primary winding hereThe coil acts, then the dishes themselves are secondary. Naturally, for use simple ceramics will not work. Here you need to have containers made of special ferromagnetic material - that's what dishes for induction cooker should be used for. As soon as it is placed on the included hob, induction currents will be induced in the bottom. Thanks to them, the products will be heated enough for their normal heat treatment. It is also worth noting that only the bottom of the dishes can have ferromagnetic properties - all the other parts can be made from simple materials. This is quite enough to heat dishes and heat food. With the technical part of these devices we figured out completely. Below we consider what inductive plates have pluses and minuses.
Benefits
The first plus induction cookers is a high efficiency. As practice shows, almost 90 percent of the heat that occurs when heated, passes directly to the food being cooked.
About security
Another interesting fact:It is impossible to get burned on the ceramic glass surface of the furnace. The whole "focus" is the special material from which the hob is made. Thanks to glass ceramics you will always be safe, even if you accidentally touch the surface of the induction cooker. However, not everything in the world is perfect, so there are risks of burns (for example, when cooking roast potatoes with an oil temperature of 150-200 degrees). And to reduce them almost to zero, manufacturers install special indicators - the device will notify you that the surface has cooled down. Therefore, with an induction cooker, you will always be safe.
It should be noted that the glass-ceramicthe surface quickly cools down, so immediately after cooking, you can safely proceed to cleaning the hob. In the case of gas, you have to wait up to 30 minutes or more, while the metal grilles and hotplates will cool down to normal temperature. Saving time is obvious.
Along with the fact that the hobInduction plate has the property of rapidly cooling down, it is necessary to note its particularly rapid heating. Instant heating of the hob in most cases is due to the presence of the Power Booster function. This means that the slab has its own independent and independent (main) burners. What does it say? The main ones "take away" all the heat energy from the dependent ones for a few minutes and, thereby, significantly reduce the time for cooking.
Functionality
In addition, the induction plate is suppliedvarious useful functions that make the use of the hob more convenient and safe. Among the many "bloat" should be noted such as:
- Automatic locking of the plate switching modes.
- The function of heating the plate only when there are dishes on its surface (it saves energy significantly).
- Forced heating shutdown, as well as an indicator of residual heat.
Induction plate inductance
The disadvantages of this hob are, but there are very few of them. To reveal the whole picture, let's look at each shortcoming separately.
The price is, perhaps, the very first barrier,repelling buyers and encouraging them to purchase cheap analogs. Induction devices stand several times more than other plates, so not everyone decides on such an expensive purchase. In particular, such an inflated price is due to a set of additional functions.
What else do inductive plates have pluses andminuses? The second disadvantage is the impossibility of heating and cooking on plain glassware. For cooking and cooking food special containers are required. This, as we already noted at the beginning of the article, dishes that have ferromagnetic properties. If you do not have one, you'll have to fork out a good buy. But after all, the plate itself is not cheap, so carefully consider carefully before buying and weigh the pros and cons.
