Modern technologies: convector oven. The choice of a stove for giving solid fuel, depending on the material of manufacture.

It's no secret that heating a room with gas is very expensive, tariffs are rising, and the quality of services provided leaves much to be desired, so many people switch to alternative heat sources, namely, they buy a stove for heating a house or any other room. Let's reveal the advantages and features of convector ovens.

Kinds

There are several varieties of such furnaces: metal, cast iron, brick.

• The first type consists of steel that can withstand high temperatures. Such a stove heats up the room very quickly, but the metal layers are extremely thin and the heat quickly disappears. For best results use stainless steel. Another weakness of this design is that its seams can burst when heated, it all depends on the quality.
• The second option is cast iron.. They are an excellent additional source of space heating. Such devices are very compact, they can be easily installed in any part of the house. A chimney is installed on it, which goes outside the room, removing combustion products. Heats up very quickly and effectively.
• The third is brick ovens, they are the most popular and reliable. Their chimney has a serpentine shape, which allows you to rationally save the product of combustion, which is a source of heat. Such an oven heats up slowly, but the brick itself retains heat for a very long time. They are very versatile, they are used as a fireplace or a place for cooking. Accordingly, the price is also higher.

What are convector ovens made of?

It usually consists of the following elements:

• Firebox - a place where the heating material (firewood) burns.
• An ashpit is a place where the product of combustion (ash) accumulates.
• A grate is a metal grate on which coals are placed.
• Kamenka is a place for sauna stoves where stones lie.
• Chimney - serves as a device for removing combustion products.
• Features and disadvantages.

Pros and cons

Such stoves have proven themselves in heating houses, cottages, garages and other premises. They are able to work in two modes: instant heat and keep warm. They are very easy to operate. Firewood, peat, coal or paper can be used as a combustion product. But let's take a closer look at all the pros and cons.

Positive sides:

However, the converter system also has its drawbacks.

Negative sides:

• When heated, hazardous combustion products are released.
• Installation problems may arise, since everything must be coordinated with the fire departments.
• The ash emitted through the chimney contributes to the pollution of the environment and the surrounding area.

What properties should a convector wood-burning stove have when heating a summer house

Of course, convector systems are multifunctional and suitable for almost any purpose related to home heating. But, for example, living quarters and summer cottages are two completely different environments that require an individual approach when choosing a stove.

Sudden temperature changes should be taken into account, so the stove needs to be heated stronger or weaker - it all depends on the situation and meet certain standards:

• It should evenly distribute heat throughout the day.
• The outside temperature should be 90-95 degrees.
• With low fuel consumption, the room temperature must remain stable.
• The entire oven must be evenly heated.
• It should not have cracks, as this can lead to the release of harmful gases directly into the house.
• The dimensions of the firebox should be taken into account, the larger it is, the longer the combustion process will take place and the heat will remain for a longer time.
• The mechanism itself should function stably for 20 years.
• The appearance of the stove is also very important for the overall atmosphere.

The most economical options

Not only the reliability of the structure depends on the quality of heating the house, but also what materials and in what quantity are used. The most common option is considered gas-fired ovens. They contain a large amount of firewood, the top layer is slowly smoldering, and the bottom is waiting for its turn. Such a result can be obtained as a result of pipe draft with blower dampers. Their house heating efficiency is 75-85%. Wood-fired gas-fired stoves are well suited for summer cottages.

Another option for economical heating is considered to be gas-generating furnaces with a large column. Firewood, peat, coal or other combustion materials are placed in it to the full height. From above fill everything with fuel and cover. Combustion air is supplied from above through a pipe.

The combustion process of the material occurs at the top, gradually moving down. The rate of combustion in the furnace can be adjusted with a damper. It functions on wood for up to 2 days (without refueling), and on coals it can heat a house for up to 5 days.

There are stoves with automatic loading of firewood. Such structures provide fuel on special discs 10–15 cm thick. The mechanism itself is a very complex system.

Wood-burning stoves with a water circuit are another type, their smoke channel is lined with heat exchange material. Thermal gases pass through special valves, giving off heat to water. To install it, you need to build a foundation with a heat-insulating pillow.

Conclusion

Convector ovens are an excellent alternative heat source that is very easy to operate and very efficient. Such ovens are very popular on the market, so manufacturers have significantly expanded their variety and capabilities.

Currently, the home appliance market has many analogues of ovens and various ovens for high-quality cooking. But recently, convection ovens are gaining more and more popularity.

The convection oven consists of a body, a heating element (heater) and fans built into it. The case is made of heat-resistant, high-quality metal. The heating element is located inside, almost close to its walls, and is continuous around the entire perimeter. Fans are also needed for directed air circulation inside the unit. There may be several, depending on the size of the furnace. The capacity is the same.

Furnace control

Control may be electromechanical- a number of rotary mechanisms. And it can be electric, push-button or touch. Temperature control can be either automatic (in accordance with the selected program) or manual, which will allow you to independently choose the temperature and cooking time you need. Information about the selected program, the temperature inside the oven and air humidity (for new generation models) is displayed on the LCD display.

Kinds

Convection ovens according to the place of use are divided into household and industrial.

Now let's talk about the pros. As already mentioned, this is a high quality of cooked food. Thanks to the indirect effect of high temperatures, the dishes retain their attractive appearance and the entire vitamin complex.

Air circulation also plays an important role. Thanks to the fans, hot air will cover the dish and pastries from all sides, preventing burning. But what about air humidity? The heating element greatly dries the air inside the chamber, therefore, the dish will not be juicy, and the pastries will completely “deflate”. This fact is not encouraging.

Manufacturers of convection ovens have taken care of this. There is a humidification function. Water is poured into a special reservoir, and the oven injects a small amount of it either onto the fan or the heating element. The fan will spray the liquid around the chamber, and the heating element will convert it into steam and moisten the dish.

Humidity regulation can be done in three ways:

Another important advantage is the huge glass in the door. It will not only allow you to monitor the dish without opening the door, but also protect the hostess or the chef's staff from burns. Glasses in such ovens are usually double-layered and have their own fan for blowing and cooling.

Another nice little thing is the cooking time. Thanks to directed air flows and a heating element that forms a closed chamber, the cooking process will be much faster than in conventional ovens. And if faster, then less electricity will be spent.

Housewives also notice that the temperature in such ovens should be set 15-20 degrees lower than indicated in the recipe.

Application

Convection ovens have found their place in cafes, restaurants and pizzerias. Dishes are prepared much faster and retain an attractive appearance for the buyer, and due to the large capacity of industrial ovens, it is possible to cook a large number of dishes at once at the same temperature.

Baking bakery products in such ovens is also very profitable, the pastries will be lush and will not lose their freshness for a long time. Recently, convection ovens have more and more functions for convenient use. For example, a delayed start, if you need to start cooking a little later. Sleep mode, which means maintaining the minimum temperature without cooling down the heating element. And, of course, a sound signal indicating the completion of the cooking process.

Aerogrill - an alternative

What is the difference between an air grill and a convection oven? The difference is not so great, but still it is worth clarifying some points. Aeroglile is reduced analogue of a convection oven, and is more suitable for home use.

The convection grill consists of a plastic stand with built-in heating elements, a glass flask, slightly expanding at the top and a lid with a handle, a built-in fan and a control unit. Dishes are located on one or more levels along the glass flask, through which, by the way, you can observe the cooking process. The fan built into the lid performs the same function - air circulation inside. But there is another arrangement of the required elements.

In some aerogrills, both a heating element and a fan are in the lid. Air humidification in aerogrills is carried out both by the cook himself and automatically. With automatic air humidification, the liquid should be in a narrow channel at the bottom of the air grill, around the heating element. With a strong drop in humidity, the water from the tank itself will begin to evaporate and circulate as steam throughout the internal volume. It is worth noting that aerogrills are used only in the domestic sphere.

We can say that the air grill is small and home analogue conventional convection oven. Due to its small size, it will find a place in any kitchen, and thanks to a different design, every housewife will find her air grill!

The convector oven belongs to professional heating equipment, which is in great demand among catering establishments. These units are used for baking frozen dough products and bakery products. Convector ovens are installed at fast food establishments, in mini-bakeries, cafes and restaurants.

The unit is presented in the form of an oven with convection, which ensures uniform distribution of hot air. The temperature is preset. The device of the furnace allows to carry out uniform baking of bakery products.

Due to convection in the oven, the set temperature is reached quickly. It also takes less time to bake. The oven doors are made of double glass, between which there is an air gap. This design reduces heat loss and saves on electricity. If you touch the door during baking, there will be no burn.

Some convector ovens have a steam function that prevents overdrying of baked goods. Steam humidification is regulated in two ways:

• manually, for this, a button is provided on the control panel of the furnace, if you press it, the nozzle will open, it injects a certain amount of atomized water into the chamber;
• automatically - a special program is set.

The lineup

On the market, convector ovens are presented in a wide range. Apach AB4D is used for cooking dishes of varying degrees of complexity in a catering establishment. The advantages of this model include:

• quick cleaning of the chamber;
• the presence of a stainless steel case;

The main functions of the UNOX XBC 405 oven include a pause in operation, the presence of 6 air flow rates in the chamber and several reverse fans. The memory of the oven is designed for 20 cooking processes. If necessary, you can combine cooking "Convection with steam". The cook can independently control the climate in the chamber.

The MAXI.Link technology provided in the oven allows you to create modules and connect the device to the necessary accessories. Protek.SAFE™ technology is responsible for the thermal insulation of the unit, ensuring safe operation and engine braking when the doors are opened. The electrical power is modulated according to the effective need.

Additional equipment

The oven is equipped with a door lock, which is made of durable technopolymer. Of the additional functions of the convector oven, there are:

• the ability to save 99 programs;
• preheating up to 280°;
• renaming a previously saved program;
• camera lighting;
• door contact sensor.

A board installed in the oven prevents steam from infiltrating the electronic parts. The product is equipped with a water collection tank with a constant flow. The design is equipped with various sensors and a safe two-step opening / closing of the door.

The modern convector oven Garbin G-PRO 4D is used for baking flour products and semi-finished products. The unit does not overheat due to the presence of a reversible advanced fan.

If it does not work, the heating elements automatically stop. The unit is equipped with 2 baking sheets, a digital timer, removable glass for the door, blades for collecting liquid and Reverse fans.

Some models of convector ovens are sold with an external temperature sensor, a sound amplification kit, software, a sewer connection kit and a special detergent for washing equipment.

Today, convection ovens are successfully used in the kitchens of restaurants, bakeries, cafes, bars, pastry shops. One of the oldest players in the Moscow market of convection ovens for fast food can be considered the KLEN company, which has been supplying equipment for bakeries from leading world manufacturers for more than 20 years. Due to the high quality of the resulting baking, the convection oven will delight not only fast food cooks, but also any housewife. They are easy to use and allow you to prepare not only bakery products, but also other culinary creations.

The operation of these furnaces is based on the principle of air exchange with hot air, due to which uniform heating of the entire surface is carried out. Basically, there are three types of such furnaces:

• furnaces with air humidification function;
• ovens without air humidification function;
• ovens with a steam humidifier, but without a humidity control function.

Convection ovens with manual humidification have a button on the panel, when pressed, water is injected into the chamber, resulting in steam humidification. A convection oven with steam humidification has a humidity parameter that is set to the desired value. Such furnaces, in turn, are divided into injection and boiler.

Air circulation in ovens occurs both in a single-turn direction and in a multi-turn direction, the effective operation and speed of processing the product depend on this property.

Convection oven control carried out by means of electromechanical or electronic influence. Electronic influence has many advantages: it is easy to set up any convenient cooking scheme, heating duration, set the end time of the product, and so on. Also, the electric convection oven remembers the most successful modes of operation, which you can repeat by pressing just a couple of keys.

Convection ovens are made from of stainless steel. The front doors are made of double glass, and this has several advantages, namely:

• the furnace chamber is protected from heat loss;
• it is possible to see what is happening inside the oven.

Also stoves equipped with features interior lighting, steam and grill functions. The temperature range in convection ovens ranges from 50 to 300 degrees Celsius.

Convection oven for home very convenient. However, first of all, you need to learn how to use it correctly. Experiment with a few familiar recipes. For example, duck will cook much faster in a convection oven than in a conventional one. For baking, use high-sided baking pans to achieve a greater convection effect. Thanks to the built-in fan, hot air blows over the food, and does not just spread from one side, as in the oven, which means that the product reaches readiness faster. Thus, uniform exposure to high temperature speeds up the cooking process. Now you can forget about such unpleasant moments as burnt pastries. Also, a convection oven will provide you with many advantages in frying and baking food.

Previously, such stoves were more used in kitchens, where did they cook fast food, and at home they were not comfortable. But over time, they were improved, and now convection ovens can be found quite often in the kitchens of ordinary housewives.

So, convection ovens have many benefits because they are versatile, practical, multifunctional. You can buy convection ovens in online stores or in networks selling household appliances.

There are many domestic and foreign convection oven manufacturers. Of course, both quality and price depend on the manufacturer. The combination of these indicators in ideal proportions is possessed, for example, by Italian Unox convection ovens and Vitesse convection ovens from France.
