One of the most discussed topics in the field microwave ovens(MVP) - its internal covering. It depends on him how easy it will be to take care of the equipment, what properties it will have, how tasty the food will be and how long the device will work. Microwave coating is the highlight of our review, we will help you choose the best option.
It is important that electromagnetic waves do not leave the limits working chamber, so the original purpose of the inner layer is to protect the user from the radiation of the magnetron. Later, manufacturers assigned other functions to the coating: to reduce electricity consumption, to simplify the maintenance of electrical appliances, and others.
To find out which better coverage for microwave, it is worth learning about the advantages and disadvantages of each type. There are four of them:
The most budgetary spraying on the walls of the MVP, which does not require special care and is easily cleaned after use from grease and other contaminants. It withstands temperature changes steadfastly, only if it is not a long exposure to high temperature - in this case, the enamel may be damaged. If you are going to buy a microwave with all possible functions - grill, convection, automatic programs, the enamel may not withstand the load, so there are few such offers.
Enamel food, pluses:
If the walls of your microwave are made of stainless steel, then it does not care about the temperature. But difficulties with maintaining cleanliness will arise immediately. To eliminate grease stains, stains and smudges, you will need constant care using special household chemicals.
So, stainless steel, pluses:
Models with bioceramic coating are recognized as one of the best. A flat and absolutely smooth surface does not allow drops of fat to settle on the walls, and cleaning does not require the same effort as stainless steel. Despite its strength, ceramics are extremely fragile, so mechanical impacts are detrimental to it.
Fact! With regard to BIO ceramics, there is a strong opinion that during cooking, a maximum of vitamins is preserved.
The technology began to spread more than 10 years ago in the Asian advanced countries - Korea and Japan, although the idea belongs to the American Aerospace Agency (NASA).
Operating principle. During heating ceramic surface emits natural infrared waves. And the material consists mainly of silicon, titanium and calcium, and titanium in it is 250% more than in ordinary enamel used for such purposes.
That bioceramics outperforms even stainless steel has been proven in independent tests carried out at the Bremen Research Institute. Advantages:
But that's not all. Let's talk about cleaning, safety and fragrances.
The material has non-stick properties, so the combustion products of oils and other food residues do not stick to the surface. So, in a stainless steel chamber, when heated at a power of 1300 W for 150 minutes, the oil will burn and leave black marks - and everything will be fine with bioceramics under equivalent conditions. Over the years, the material, also unlike stainless steel, does not lose color. And if you purchase a model with an innovative Easy Clean coating from LG or Gorenje, maintenance is practically not required.
This is a harmless material, especially considering that it is used in surgery, medical accessories are made: belts, bracelets, etc. There are 24 types of bioceramics in composition and purpose.
If you choose, for example, the model from Samsung - GE83XR / BWT, each dish will smell only of its ingredients, and not of the food that was cooked before. This eliminates the need to clean up after each use.
There are cons, and it is impossible to hide them:
Not only plumbing is covered with acrylic - this material has also found application in the design of MVP. Despite the fact that the technology was applied not so long ago and could be of interest to the user, there is still no active demand for models with acrylic. Moreover, the buyer is waiting for a choice only from budget models, with a power not exceeding 1400 watts. Usually found in solo models, which are used at most for heating and defrosting food.
Surprisingly, acrylic has a lot of advantages:
You can meet acrylic walls in budget, but very high-quality MVPs from such well-known brands as Samsung and Daewoo. For example, a small solo model Daewoo KOR-4115, designed for 14 liters and a power of 600 W, has acrylic walls. Users successfully use the stove to thaw frosts, heat food, make hot sandwiches - as they say, a typical microwave oven.
In order for the equipment to last as long as possible, follow a couple of rules:
Obviously, bioceramics has become the winner, in view of its merits and impeccable properties, but one drawback can confuse the lion's share of buyers - the cost. Therefore, it remains to choose from the remaining three - here we are not advisers, because the choice depends solely on your preferences and the intensity of operation of the equipment.
As a rule, the choice of a microwave oven involves the evaluation and analysis of various characteristics and qualities of the product. It is from this that its effectiveness and durability will depend in the future. One of these important features is the interior decoration of the microwave, the role and varieties of which will be discussed in this article.
In order to determine which internal coating of a microwave oven is better, you need to familiarize yourself with all its functions and varieties.
The inner coating in a microwave oven performs several functions at once. The main task of finishing is to prevent the leakage of electromagnetic waves and reduce their negative impact for products. Thanks to it, the waves are kept inside the microwave, thus not harming health and reducing extra expense energy.
Exposure to electromagnetic waves
The level of thermal conductivity is also responsible for the consumption of electricity. interior decoration. The higher it is, the faster the dishes will be cooked and, accordingly, the less energy consumption will be.
The quality of the interior decoration itself is also important, because it directly depends on what the cooked dish will be like. Some materials may contain harmful substances that, when heated, are released and absorbed into products, giving them a specific taste and smell.
influences interior design and the life of the device. The stronger the material, the less it will undergo mechanical changes (dents, scratches, chips) and, accordingly, will last longer.
Different types of microwave ovens
Depending on the type of material used, there are 4 main types of interior coating finishes:
All of them have various properties, their positive and negative qualities.
Such coatings include heat-resistant enamel and. This material is used mainly in budget options for microwaves.
TO positive qualities models with enamel finish include availability and a wide range. Also, such ovens are resistant to sudden changes in temperature, easy to operate and, with proper care, quite practical.
However, microwave ovens with an enamel coating also have their drawbacks. First, they are highly susceptible to mechanical damage. Secondly, they cannot withstand high temperatures for a long time. Thirdly, when heavy pollution enamel is quite difficult to clean with gentle detergents, and the use of abrasive substances is strongly discouraged.
Enamelled finish
Home hallmark such coating is durable. This heat-resistant surface is able to withstand high temperatures for as long as possible and is extremely resistant to its sudden changes. In addition, the stainless coating has high strength and is not afraid of mechanical damage, due to which it can last long years. The advantages of such a surface include high thermal conductivity, which in turn reduces energy costs.
Stainless steel microwave
As for the disadvantages of stainless steel, here it is worth noting some difficulties in operation. The point is that on metal surface fat accumulates very quickly, which is quite difficult to clean off. As a rule, for this it is necessary to resort to the use of various detergents, long-term use of which spoils the surface over time. She scratches and rubs, thereby losing her appearance.
In addition, stainless steel microwave ovens cannot boast a wide range. To date, only a few models of this type can be found in stores.
metal plating
Microwave with such a coating is rightfully considered the best. They have significantly more advantages over their enameled, metal and acrylic counterparts.
The ceramic surface is very even and smooth, due to which grease does not accumulate on it. It is easy to clean. In this case, there is no need to make great efforts or use special detergents.
ceramic coating
Ceramics - ecologically pure material. Due to this, the products during the cooking process are not affected by harmful substances and do not absorb foreign odors. There is also an opinion that dishes cooked in such a microwave oven retain their useful qualities better, in particular, without losing vitamins E and C.
Ceramic microwave ovens are distinguished by good thermal conductivity. The food in them quickly cooks and warms up, but it does not burn. Pleases in such microwaves and a long period of continuous operation.
Other advantages of microwave ovens with ceramic inner coating also include durability, attractive appearance and the presence of antibacterial properties.
Against the background of all the positive qualities of this coating, its inherent disadvantages seem insignificant. However, when buying such a furnace, it is still necessary to take into account the fact that excessive mechanical stress can lead to cracks or chips in the interior finish.
The disadvantages of ceramics include high cost. However, today more and more new models appear in stores, the price of which does not differ much from the same enameled counterparts.
ceramic coating
Microwaves with acrylic coated are considered a kind of know-how in their field. They appeared not so long ago and have not yet gained much popularity.
It is worth choosing such a microwave only if you do not plan to cook anything at high temperatures. The maximum possible power of such microwaves is up to 1400 watts. They are suitable for defrosting food, reheating and cooking at low temperatures.
The positive qualities of acrylic include:
acrylic coating
Summarizing all of the above, it is impossible to say exactly which inner coating it is better to choose a microwave oven with. Each of them has its pros and cons.
Products with a ceramic coating are most likely to be preferred by those for whom decisive factor is an maximum level safety and long service lines.
If the priority is cooking speed and low energy consumption, then better option than a metal-coated microwave is not found.
Models with acrylic and enameled inner surface are among the budget options. They are very relevant if the oven will be used only for the simplest functions (defrosting, heating).
Among other things, when choosing a microwave, you should also pay attention to the presence of additional modes, functions and components. In this case, the manufacturer is also important.
Range of microwaves
Bioceramics in a microwave oven.
Infrared microwave bioceramic technology was commercialized ten years ago in Japan and Korea. Bioceramics is an innovative technology of the American Aerospace Agency (NASA), which has become firmly established in everyday life due to its unique properties.
If you have a choice, then buy with bioceramics (not much more expensive than other coatings and stainless steel). The principle of operation - when heated, including microwave, this ceramic begins to radiate quite intensively natural waves of infrared radiation. The main composition is silicon, calcium, titanium. Bioceramic enamel contains 30 percent more silicon and 250 percent more titanium than traditional enamel.
Based on the main physical properties and laws, as well as independent tests carried out at the Bremen Research Institute for Applied Materials (Fraunhofer, Germany), it was possible to prove that the bioceramic coating is superior to stainless steel in a number of the following indicators.
Pros?
Improved vitamin retention.
Foods cooked in microwave ovens with a ceramic enamel coating retain much large quantity vitamins C and E compared to foods cooked in stainless steel lined ovens. After heating 200 ml of a 1.5 mg/ml vitamin C solution in a Samsung bioceramic coated oven, much more vitamin C remains in the solution than when heated to similar temperatures in competitor models with a stainless steel lining. become.
Saving time and energy.
The thermal conductivity of the bioceramic enamel coating is more than 2.4 times lower than the thermal conductivity of the stainless steel coating. This is what keeps more heat inside the oven and saves energy and time by 9, 5 and 11 percent, respectively.
In this way, the preparation of more delicate food is achieved in more a short time and consumes less electricity.
High resistance to mechanical damage.
As a result of mechanical impacts of the same force on bioceramic enamel and stainless steel, the roughness of bioceramic increased by only 7.5 percent, in contrast to stainless steel, whose roughness increased by 106 percent.
Experiments have proven that as a result of washing and removing dirt on inner surface bioceramic enamel almost never leaves scratches.
Ease of cleaning.
The bio-ceramic enamel surface has high non-stick properties and almost does not leave stains as a result of the combustion of oils and other food residues. As a result of heating for 150 minutes at a power of 1300 watts, edible oil burns to the stainless steel surface, leaving black spots, which does not occur on the bioceramic enamel surface under identical conditions. Unlike stainless steel, ceramic enamel does not change color and its smooth surface is easy to clean.
Security.
Let's make a reservation right away - there are more than 24 main types (types) of bioceramics, as chemical composition, and purpose. In total, several thousand are used.
Applications in everyday life and health: bone surgery, medical bracelets, belts and even rugs on the stomach.
The infrared range is a natural heating range that a person has been using for thousands of years to heat food and warm himself (from a fire and heated stones to the sun). The safest and most useful of them is infrared radiation with a wavelength of 4 to 14 microns. The most useful is the 9 micron radiation, which most closely matches the resonant frequency of water molecules. Bioceramics emitting IR rays with a wavelength of 4 to 14 microns, i.e. the same as that of the sun's rays, which ensures maximum safety and convenience.
Our body itself emits infrared waves in the far range from 4 to 14 microns.
Bioceramics in a microwave oven.
When choosing a microwave oven, buyers pay attention to design, functionality, dimensions, the possibility of embedding, price. But do not lose sight of another important feature - the coating of the microwave. Especially if you are going to spend a large amount on equipment. Let's talk about which options are better to choose in order to protect yourself and ensure the smooth operation of the microwave oven for many years.
Electromagnetic waves, which are produced by the mechanisms of a microwave oven, should not leave the chamber - this will not only lead to an overrun of electricity, but also harm a person. These are the most important factors to consider when choosing. But no less important are such details: how resistant the coating is to abrasion, scratches and mechanical stress, how easily it gets dirty and cleaned, etc.
Choosing an inner lining potential buyer faces four different options:
The most profitable in terms of cost. It is easy to wash fat from it, and temperature fluctuations are not terrible for her. The only exception is too high a temperature that remains in the chamber for a long time. If the goal is to buy a multifunctional model with grill and convection options, and not, you should not dwell on this type.
Advantages:
Disadvantages:
On a note! Samsung has launched a line of new microwave ovens with Easy Clean. This is the same enamel, just, according to the manufacturer, it is 10 times easier to clean.
The stainless steel chamber will easily endure any modes at the highest temperatures. But achieving the ideal frequency on a daily basis will not be easy. The fat remaining on the wall after cooking is washed off only using specialized products. To get rid of stains, streaks or smudges, you will need to make an effort.
Advantages:
Disadvantages:
In principle, this is the same thing with a slight correction: bioceramic enamel appeared relatively later than ceramics.
The ceramic chamber is recognized as one of the best - grease practically does not stick to it due to the ideal smoothness of the deposition. Cleaning takes no effort. The strength of the material is at a height, but it is better to avoid mechanical impact so that chips and cracks do not appear.
A number of experts argue that it is in a chamber with a bioceramic coating that the nutritional value, vitamins and other useful material products.
Advantages:
Disadvantages:
This is a recently invented technology that has not received proper distribution. Acrylic chambers are used only in inexpensive options Microwave ovens, the power of which does not exceed 1400 watts. They will be able to warm up lunch, defrost a semi-finished product, please you with a hot sandwich - but no more.
The material is bad because it only works at low power.
If the years of using the microwave oven are already behind, and the enamel layer is slowly fading into oblivion, you can try to restore it yourself using quite affordable materials.
Most often, when irreparable defects in the internal coating appear, users “say goodbye” to the old assistant and go for a new one. But there are people in whose hands any technique is restored. For such craftsmen, we have helpful tips for painting the inside of a microwave oven.
You need to start by choosing a paint that must meet certain criteria:
Before you cover the inside of the chamber, examine the range of paints suitable for this undertaking.
An ideal choice, but the price "bites". The composition is resistant to any influences: temperature fluctuations, alcohol vapors, acids, humidity. For the human body, they are absolutely harmless, because the composition is designed specifically for use in Food Industry. Flawlessly lie evenly on metal, aluminum.
Enamel compositions for the food industry are usually used to paint containers under drinking water, so you can not worry about their environmental friendliness. The paints in question consist of zinc powder and an alcohol solution that has undergone a special treatment.
Fact! Enamel prevents corrosion processes in the microwave oven due to "cold galvanizing", able to withstand temperatures up to 100 degrees, resistant to moisture.
In the composition you can find zinc, aluminum, silver or shungite. Drying, the layer becomes resistant to environment, able to tolerate t ° up to 200 degrees. It is rarely used in coating furnaces due to the high cost.
Shungite is a rock with excellent energy-saving properties. 1000 kg of this material contains 300 kg of shungite carbon, the active properties of which are higher than those of coke. It is dense, durable, electrically conductive, so the bases, both anti-static and heat-resistant, come out of it what is needed. Feel free to take such paints for the microwave oven.
Cheap and cheerful. Requires sanding rust, degreasing the surface. Available in balloons: one is enough for one stove.
Here you are unlikely to learn something new, but just in case, study the stages of painting:
Now you know everything about microwave oven covers: what they are, what are their features, how to restore them with your own hands. Good luck with your choice or repair!
The microwave oven is one of the youngest representatives household appliances for kitchen. Her age does not even reach 70 years. The patent for the production of these products was obtained in 1945 after the great invention of Percy Spencer.
Initially, microwave ovens were only available to restaurants or large establishments because the price of the appliance was prohibitive. In addition, the weight of the great-grandmother of the microwave oven was about 340 kilograms.
Today, microwave is a compact device that does not take up much space, with many functions. This is no longer a curiosity, and the device can be found in almost every kitchen. But how to choose a microwave for your home when there are so many models from different manufacturers on the market?
There are a lot of rumors about the danger posed by the microwave oven.
The very first is harmful radiation during its operation. but modern appliances completely safe for humans, as they are developed according to special technologies and have the appropriate certificates, according to which all microwaves are tested for radiation.
The safety principle of the furnace is based on its design, namely, the application of a special magnetic trap and a protective grid to each model, which absorbs harmful rays when the door is tightly closed during operation.
To evaluate the safety of a microwave oven on your own, you can conduct a small test. While in the store, put in the product cellular telephone, close the door tightly and make a call to the gadget.
The absence of a network will prove the safety of the microwave, dialing - evidence of weak protection, but still its presence.
A modern microwave oven is not only a convenient and time-saving product, but also a protection of human health. Cooking food in the microwave preserves everything to the maximum beneficial features and vitamins in meals. The same cannot be said for food cooked on a standard stove.
Before choosing a microwave oven, you need to decide what it will be used for. If you only heat food in it, you should not take a heaped up model, an inexpensive stove with a food heating function is quite enough. This will be the most economical and suitable option.
The main "skills" of a microwave oven, which guide buyers before buying, are defrosting food, heating food, the ability to cook various dishes, including steaming, and the presence of a grill.
Choose a microwave that suits your budget. The price range for modern optimal devices with good set opportunities starts from 3,500 rubles and can rise to 10,000 rubles and more.
You can buy a microwave and cheaper - from 1,500 to 3,000 rubles, but such products will not be the best, the heating or defrosting process will be very long due to the low power.
After you select the features you need, check out the main features different models. These include the following indicators.
Enamel. It is a heat-resistant and wear-resistant coating.
It is easy to remove carbon deposits from enamel, while spending a small amount of time.
Also enamel is quite loyal to sudden temperature changes.
But too high temperatures will become stressful for her, so a microwave with an enameled inner coating will serve the owners for no more than 7 years.
The main disadvantage of such a coating is the ability to easily scratch the surface, which will further reduce the life of the equipment.
stainless steel. Steel is the most durable material. The owner of such a coating is not afraid of temperature changes, she does not mind too high temperatures, it is simply impossible to damage or scratch the inside of the furnace.
However, even such a coating has a drawback - very rapid pollution and difficulty in care. Grease splashes, soot cannot be removed as easily as from an enameled surface. Here you will have to tinker a lot before the stove shines with cleanliness;
Bioceramic surface- example new development, which perfectly combines the features of enamel and stainless steel. Scratch resistance, ease of maintenance, tolerance to sudden temperature fluctuations - these pluses make the microwave oven the best and longest serving.
It costs much more than the others (almost 2-3 times higher than the stove with enamel coating and 1.5 times with stainless steel coating), but in this case the end justifies the means.
According to the type of control, microwave ovens are divided into two groups.
As mentioned above, the main role in choosing a particular model is played by a set of basic functional microwave features.
In addition to the main ones, modern microwave ovens have a number of other additional features.
If the quality of the prepared dishes matters to you, then purchase a microwave oven with a convection mode that will allow you to cook food evenly - bake a flour product or fry meat. At the same time, all the useful properties of the products will be preserved. The only downsides are the high price and energy consumption.
An important point when buying an oven should be the question of what microwave utensils should be used. This is, first of all, porcelain, ceramics or glass.
There is also a wide range of plastic containers equipped with special icons that allow their use in the microwave. However, when buying an oven, you need to pay attention to the containers and trays that come with it.
Due to them functionality will be significantly expanded.
So, having understood the rules for choosing the optimal microwave oven, it remains only to purchase the most suitable model. Below is a list of the most popular microwave ovens, which was compiled based on customer reviews.
This is the most popular microwave oven, moreover, it has collected a lot of positive feedback. The volume of the device is 20 liters, however, highest power not very high - only 700 watts. The microwave has a digital display and touch controls.
