What is convection in an oven. Convection oven - what it is, the principle of operation, an overview of models with a description of functions, photos and cost. Injection and boiler furnaces

Convection ovens are analogues of ovens and ovens that allow you to cook food quickly and efficiently. This specialized equipment is designed to facilitate human work and reduce cooking time. This versatile oven combines the qualities of a steam cooker and an oven. For the first time such a device appeared in 1976, it was invented by the Rational company from Germany.

Since that time, these ovens have changed dramatically, turning from primitive manual units into complex systems that provide cooking with little or no human intervention. For baking and cooking dishes, such units can use different combinations of steam and convection. The main advantages of such furnaces over other equipment are high efficiency and ease of use.

Kinds

Convection ovens can have different designs, functionality, including different performance. By type of use, the units can be:

Industrial.
Household.

Home appliances are popular among housewives who love to pamper their household with delicious and healthy meals. They are about twice the size of a microwave oven. On average, the useful volume of such a furnace is about 25 liters. In such an oven, several medium-sized baking sheets fit.
Industrial versions of ovens are often used in restaurants, cafes, canteens and pastry shops. Such models are very convenient for making sweets, pizza, pies, cakes and other pastries. They allow you to cook a large number of dishes at the same time. On average, their capacity reaches 500 liters. However, industrial units are distinguished by large dimensions and weight.

These furnaces can be divided into groups depending on specific criteria. For example, if a particular unit has an air humidification system:

Steam Humidifier Furnace.
Oven without humidification.

The first option is good for baking bakery products. Thanks to the moisturizing device, the products are lush, soft, they will not dry out. The cake will look incredibly appetizing.

Furnaces can also be with manual or automatic air humidification. In devices with manual humidification, there is a button that, when pressed, directs water into the chamber. It is sprayed and gets on the fan, spreads over space. In this case, there is no way to adjust the humidity. With an automatic system, the oven has a steam humidifier, which does not require human control. He only needs to set the required humidity parameter, after which the oven itself will control the entire humidification process.

Steam convection ovens can also be of two types:

Injection.
Boiler rooms.

Steam is generated in boiler plants. For this purpose, a container with water is used, from where liquid is injected into the chamber. In injection versions, steam is created using a water atomizer and a heating device.

According to the type of energy used, furnaces can be:

Gas.
Electric.

Gas ovens can run on natural gas, including propane. Mostly, such models have a powerful and durable design that can withstand significant loads. The main advantage of such furnaces is efficiency. Electric models are less economical, but also very popular.

According to the type of control, furnaces can be of the following types:

Mechanical.
Touch.
Electromechanical.

Convection ovens with a mechanical control panel are the cheapest and simplest. However, these are the most reliable devices, but with a limited set of functions. In electromechanical devices, mechanical buttons and elements have something in common with touch elements, including various indicators that report humidity, temperature, and the like. In touch devices, control is carried out using the display. Some units are even equipped with a control panel.

Device

Convection ovens include the following main elements:

The body of the furnace is made of heat-resistant metal. The heating element is located inside, it is tightly adjacent to the walls of the furnace. It is this element that sets the required temperature. With the help of a fan, the movement of air masses inside the unit is ensured. Management is carried out using the control panel. It can be touch, mechanical or electromechanical.

Operating principle

Convection ovens are called so because they work on the principle of convection. This means that this device provides a forced and uniform distribution of heated air masses. The heating function is provided by special heating elements in the form of heating elements or it can be gas. The circulation fan is engaged in uniform distribution of air masses.

In the cabinet of the oven there are several shelves-trays, on which plates with dishes or molds with dough for subsequent baking are stacked. Having started the oven using the control panel, the electric heater starts to heat the air, and the fans evenly remove heat from the heating element throughout the cabinet. Such an oven in a sense represents an ordinary oven. However, the main feature of the convection unit is the uniform distribution of heat. Products in this oven are evenly baked or fried at any level of the cabinet.

Convection provides an accelerated transfer of energy from the heating element to baked goods and products using heated air mass flows. The gas furnace, unlike the electric version, is a combined type device, where the air masses are heated using gas, and their redistribution is carried out using electric fans.

To soften the outer layer of the dough, also for baking bakery products with a glossy and attractive crust, water is injected into the chamber and steam is also supplied. The oven, equipped with steam humidification, makes it possible to bake products of the highest quality. As a result, the finished dish turns out to be tastier, and it takes an order of magnitude less time to prepare it. These products can be sold at a higher price and provide the manufacturer with greater competitiveness.

Application

Convection ovens are used everywhere. They can be used for home and industrial applications. Industrial models can often be found in cafes, bakeries, restaurants, pizzerias, pastry shops and other catering establishments. Small models are great for home use.

Dishes in such ovens are cooked much faster. Their products are juicy and appetizing. In industrial ovens, due to their large capacity, it is possible to cook a significant number of dishes at a given temperature. Baking in such units turns out to be lush, it will not lose its freshness for a long time. In addition, convection ovens today acquire more and more important functionality. For example, this is a delayed start, which allows you to start cooking after a while. Sound signals that indicate the readiness of products, sleep mode and the like.

How to choose

Convection ovens should be selected based on a number of criteria:

You should pay attention to the dimensions of the device. In most cases, such units stand out for their impressive size. The ovens are 1.5-2 times larger than a conventional microwave oven. Therefore, it will be necessary to take care of allocating free space for this unit in advance.
The presence of the steam humidification function, which is very important for this unit. Thanks to this function, the dishes will lose a minimum of moisture, so they will be appetizing, juicy and very healthy.
type of steam humidifier. The devices may have manual and automatic steam humidification. In manual mode, it will be necessary to press the button so that water is sprayed onto the heating element.
programming function. The required baking cycle is provided by the selection of the available program. This is quite convenient, but the presence of such a function makes such a unit somewhat more expensive.
Power. The high power of the device will allow you to heat up dishes faster, as a result of which they can be cooked somewhat faster.
Look closely at the design so that the stove fits into the interior of your room.
Furnaces are produced by many manufacturers, so there are many models with different designs. Choose an oven that has a clear and informative control panel .
The selected model should be easy to use and maintain.
It is recommended to choose a certified stove made of quality materials.
You should not get carried away with numerous additional functions, since the stoves will be an order of magnitude more expensive than simple stoves. Mechanically controlled ovens are considered the most reliable devices.

The household appliances market has recently been enriched by another type of oven - a convection oven. The novelty quickly gained great popularity, gradually replacing traditional ovens from the top positions in the rating.

Design features of the convection oven

To understand what an injection furnace is, you need to carefully study its design. It includes a housing, a heating element and an internal fan. High quality heat-resistant steel is used to manufacture the body of the device.

The heating element continuously passes along the entire perimeter of the chamber, close to its inner walls. Thanks to the fan, the heating elements are directionally blown by air currents. Large ovens are usually equipped with several fans.

Management specifics

The control panel can have the following design:

Electromechanical. Consists of several rotary controls.
Push-button.
Touch.

To adjust the heating temperature, manual adjustment and automation can be used. The LCD display provides information on how the convection oven is operating, showing the selected mode, operating temperature and cooking time.

Varieties

Convection ovens are domestic and industrial:

household. Designed for home use. Devices of this type are approximately 1.5-2 times larger than conventional microwave ovens. The average volume of a household model is 25 liters, which allows 2-4 baking sheets to fit inside.
Industrial. Confectionery, cafes, bars, restaurants, etc. are equipped with such devices. They are very convenient for making pies, cakes, pizzas, sweets and other baked goods. The size and weight of such devices are very impressive. The average capacity of an industrial convection oven is 50 liters.

All models are characterized by a high quality of cooking, which is facilitated by the fact that high temperatures affect it indirectly. As a result, all dishes are very attractive, retaining all the vitamins and nutrients.

Features of air circulation

The presence of a fan allows hot air to blow over the prepared dish from all sides, protecting it from burning. In addition, the cooking time is significantly accelerated, which allows you to save on electricity. To compensate for the excessive drying of the air in the stove by the heating element, the manufacturers placed a special humidifier inside it.

It consists of a special reservoir and an injector: water is poured into the container before cooking, and then injected in small portions onto the fan blades or onto the surface of the heating element. Thanks to the fan, water is sprayed through the chamber, after which the heater turns it into steam. As a result, dishes do not lose their juiciness and do not settle.

Three methods are used to adjust the humidity inside the oven:

Mechanical. The simplest option is how to cook with a convection oven in manual mode: liquid is injected here after pressing a certain button.
Auto. In this case, the device itself regulates the internal humidity, the level of which depends on the selected program and temperature.
Intuitive. It is used in the latest developments, which are specially equipped for this purpose with air humidity sensors. Information from them goes to the built-in mini-computer, which itself decides on the need for additional moisture. Such devices work practically without human intervention.

Glass door

This allows you to visually control the cooking of the dish without stopping or opening the oven. Thus, the risk of burns for the cook is minimized. Convection ovens are usually equipped with double-layer glass with an autonomous blowing and cooling system.

Applications

The staff of modern restaurants and cafes practically cannot imagine themselves without convection ovens. This is due to the high speed of cooking, while maintaining their attractiveness. The significant capacity of industrial models makes it possible to cook a lot of food at a time using a stable temperature regime. Baking turns out magnificent and tasty: it is able to maintain its freshness for a long time.

Developers are investing more and more useful features in each new model. The delayed start mode is very convenient, allowing you to turn on the device with a planned delay. In sleep mode, the minimum temperature is maintained by a non-cooling heating element. Thanks to sound signals, there is a notification about the end of the cooking process. Before choosing a convection oven, it is recommended to clarify its functionality.

Good alternative

An air grill is often called a smaller version of a convection oven: most often this device can be found in a domestic version. Its design includes a plastic stand equipped with an internal heater, a glass bulb (with a characteristic upper extension) and a control panel. One or more levels along the glass flask can be used to set dishes: its transparent surface makes it possible to visually control the cooking process. Inside the air grill there is a familiar fan that blows on the dishes being prepared.

Some air grill models have a different design, which involves the placement of a heating element and a fan on the surface of the lid. Humidifiers here can also have an automatic or mechanical principle of operation. Automatic systems consist of narrow tubes at the bottom of the appliance, in the area of the heating element. When the air in the chamber dries up, the container itself begins to evaporate water, filling the entire inner chamber with steam.

A convection oven is a specialized piece of equipment primarily used by restaurants and bakeries. Such devices provide high quality cooking of various dishes.

Photo of a convection oven

A convection oven is an indispensable attribute of a modern bakery. Although a convection oven for the home is not uncommon today. It is preferred to be used in cooking by those who love high-quality and healthy food.

But how does it work? Let's take a look at convection ovens.

The equipment got its name due to the principle of operation - convection;
Convection is the uniform distribution of air heated to a certain temperature. Air distribution is forced;
In addition to culinary business, there are convection heating fireplaces. The air is heated by special heating elements or gas, and circulation fans are responsible for the distribution of heated air inside the premises;
The back wall places a fan on its surface. It is he who sets the movement of air currents;
The presence of a fan allows the heated air not to settle at the bottom, but to circulate inside the working space of the chamber;
Due to circulation, hot air affects dishes, bread from all sides, which eliminates the possibility of getting raw or burnt food;
In large industries, a conveyor oven is popular, as it allows you to put the production of dishes on stream. The conveyor oven gives out finished products, immediately after the chambers are emptied, it fills them with the next batch. The conveyor oven is most commonly found in bakeries.

Benefits of convection ovens

When planning to organize a mini-bakery, or set up a mini-production of fast food, many choose a convection oven for these purposes.

Mini models of convection ovens or large devices provide a number of advantages.

Environmental friendliness. The convection oven is a safe equipment, cooking in which does not harm people or the environment.
Small power consumption. The convector oven allows you to save on electricity, since the heating of the working surfaces occurs quickly. Compared to the same microwave, it takes much less time to cook here without sacrificing quality.
Benefit. The convector oven allows you to cook healthy food, make meat dishes less greasy. Bringing products to readiness, useful minerals and vitamins are preserved in them.
Even cooking. Here, the option is excluded when the dish burns or becomes ready on the outside, but remains raw inside. Due to the uniform circulation of hot air, your dishes will always be at the highest level.
High heating rate and maintaining the set temperature at lower energy costs.
Accelerated cooking process. You will spend less time on cooking, which will allow you to pay attention to other things.
Compact dimensions. With all its advantages and performance indicators, convection ovens will not take up much space. There are mini models. Mini stoves are used for small industries, fast foods, mobile tents where food is prepared.
Democratic price. Mini baking and cooking devices can cost $200 and up. The unox convection oven deserves special attention. It has excellent technical characteristics. These stoves cost an average of 600 to 2500 dollars.

Do they have disadvantages? Hard to say. A definite disadvantage is the dependence on electricity. To open a mini-bakery or a mini-production for the sale of street food, you will need to provide for the possibility of connecting your mini-oven to an electricity source.

Furnace Requirements

When choosing a stove based on the principle of convection, it is important to pay attention to the main parameters. So you will be able to purchase the model that is optimal in terms of characteristics and cost.

No handicraft. Choose only those stoves that are made by leading manufacturers. Never be shy even for well-known brand products to require all certificates.
Power. To cook pastries and dishes in certain quantities, the appropriate power is required. Mini ovens for baking have small parameters, but they are quite enough for home use. It makes no sense to pay for powerful devices if you do not plan to make large-scale baking for sale or open some kind of fast food.
Functions. Modern convection ovens are filled with all kinds of functionality. But experience shows that users often do not use even half of the oven's capabilities. What's the point of paying money for something you won't use?
Doors. Look at the design of the stove door. In the best convection ovens, the door is made of two layers of glass, between which air is enclosed. This ensures natural convection which prevents the outer glass from overheating. Plus, with this structure, less heat loss is observed.
Service centers. It is not worth repairing a convection oven on your own. It is better to choose manufacturers whose service centers are in your city.
Dimensions. Mini models are used for home use, and larger devices are suitable for production. It all depends on the purpose for which you buy a convection oven.
Maximum heating temperature. Certain dishes require high temperatures to cook. Not all models of convection ovens are designed for them. Therefore, determine in advance what the stove will be used for and what temperature parameters you need.
Appearance. Here already focus on your own tastes. There are a huge number of design options for convection ovens, so you will have plenty to choose from.

Steam convection

The steam convection oven deserves special attention. You should know the main points about it.

This is expensive equipment, which is a type of convection oven;
The main feature is a complex design and the ability to control the level of humidity inside the stove;
Based on the high cost of such a model, most buyers prefer conventional convection ovens with a steam function. Steam convection ovens are the prerogative of large industries;
The device is distinguished by the functionality of the fan, which, in addition to air, supplies water. It is sprayed inside the working area, turning into steam;
The function of paroconvection is important for industries that are engaged in the manufacture of pastries;
There are manual and automatic models of convection ovens. For the former, moisture is supplied by pressing a special button on the panel, and automatic devices do not independently control the level of humidity, based on the type of dish being prepared. They simply dispense a certain amount of water automatically. Therefore, such systems are imperfect;
Due to the steam convection, the dishes do not dry out, a beautiful glaze is formed on the baking surface, keeping all the useful properties of the product under the crust.

Convection ovens have their own undeniable advantages that allow them to be used for the benefit of the quality of products. Whether you need a similar oven at home or you want to start your own production, always choose high quality convection devices.

Often on the price tags in household appliances stores you can see the inscriptions: microwave oven with convection, oven with convection, mini-oven with convection. At the same time, people do not always understand what this function is for, what it is and what advantages it provides.

Convection is a system of air distribution inside the chamber by means of a fan, which ensures an even distribution of heat. In ovens and mini ovens, heating elements are located at the top and bottom. Accordingly, near the bottom and near the ceiling, the air warms up more intensively. A cake placed on the lower level from below will be baked more strongly, and on top it will hardly brown.

If you place two baking sheets in the oven at the same time, it turns out that they will fry differently. Layers in the middle may not bake at all. To avoid this situation, convection is installed in the oven. This is the most efficient and easiest way to get evenly baked products. The fan provides constant air circulation, as a result, the temperature throughout the chamber is equalized.

Microwave ovens with convection

It is known that microwave ovens are generally not intended for cooking. The microwaves emitted by the magnetron dry the product, rather than baking it. That is why many manufacturers install a grill in them - an additional heating element. With it, you can not only heat up, but also bake food. A convection microwave always comes with a grill. Teng heats the air, the fan distributes. Thus, a piece of meat or a pie is baked not only from above, but also from below. A microwave oven with convection will cost significantly more than a model without any additional features. And it is worth buying it only if the owner plans to cook in it regularly.

Cooker with convection

It is believed that a convection stove bakes better, especially if the pies are placed on 2 levels at once. In addition, with the help of a fan, you can successfully dry vegetables and fruits: hot air will blow over the pieces and quickly remove moisture.

Mini ovens with convection

Recently, mini-ovens with convection have become popular. These are small devices for cooking, in fact - desktop ovens. Most often they are purchased for country houses and cottages. In such places, free space is limited and there is no way to put a full-sized stove, but the need for cooking remains.

Functions of mini ovens

Mini ovens perform the same functions as conventional electric stoves. Inside the chamber, manufacturers install 2 heating elements that heat and bake food on a baking sheet. In more expensive models, there is a grill - a more powerful additional heating element, a spit and convection.

A skewer is a metal pin on which food or a piece of meat is placed. The pin rotates and the product is baked from all sides. This way you can cook a grilled chicken, a piece of meat or even a portion of kebabs. Very often, together with the spit, convection occurs. This is an easy way to both reduce cooking time and get a product that is baked more evenly, because the dish will be fried not only from above and below, but also from the sides.

Models of a higher price category may come with electronic control. In this case, the temperature and operating modes are selected with the buttons, and the display shows all cooking parameters, including the time remaining until the end of the process.

Control

As a rule, modern mini-ovens come with mechanical control - handles with which you can adjust the operating parameters. Depending on the model of switches, there may be several:

Temperature regulator.
Mode switch.
Timer.

Using the mode switch, you can choose which of the heating elements will participate in cooking. You can only turn on the top heater, you can only turn on the bottom one. There are “grill and convection”, “two heaters and a skewer” modes, etc. Some models have a defrost mode. One convection can also work - this will allow you to dry a portion of mushrooms, berries or greens in a short time.

Volume

One of the most important characteristics of mini-ovens. The larger the volume, the more space the device will take on the table surface. But on the other hand, the more products it will include. In a model with a capacity of 10 liters, it is unlikely that it will be possible to place a whole chicken carcass, and the area of \u200b\u200bthe grill will not allow you to cook a large pie. Furnaces with a capacity of 30-50 liters are much more capacious. They are much more suitable for a large family.

Equipment

Depending on the model, the mini-oven may come with:

Lattice
baking sheet
skewer
grip
Instructions and warranty card
Additional grid, crumb tray.

As a rule, the kit comes with a small baking sheet on which you can bake several apples or a small leg. If the model is larger, then the sheet with which it is completed is much larger. However, nothing will prevent the owners from buying a separate silicone mold for making pies or a deep glass dish for roasting. The main thing is that it fits inside without touching the heating elements, which, unlike conventional ovens, are not closed in any way in mini-ovens.

Burners

Some mini-ovens are additionally equipped with burners located at the top of the device. Such models can not only replace the oven, but also a full-fledged stove. On electric burners, you can cook soup, boil tea or fry potatoes. As a rule, such models are quite voluminous.

Power

On average, the power of the heaters of the inner chamber ranges from 1-1.5 kW. The more power, the faster the oven warms up and the food cooks, but the more electricity will be spent. Burners also give a load to the network. Their total power ranges from 1.5-2 kW. Therefore, if all heating elements are turned on, the load on the network will be higher than 3 kW, which means that not every wiring will withstand this.

The aroma of freshly baked bread and the taste of buns, muffins, pies, crispy baguettes and cookies are unlikely to leave anyone indifferent. With professional convection ovens from the WhiteGoods online store, your pastries will always turn out especially appetizing and delicious. The exceptional qualities of bread, buns and other delicacies will undoubtedly make your products stand out from the rest of the assortment, winning the love of the sweet tooth.

Own bakery production increases the prestige of a restaurant, hotel, confectionery-coffee shop, cafeteria or supermarket. Buying convection ovens is the best solution for catering establishments and bakeries that intend to bake their own bakery products in the traditional way, but using the most advanced kitchen equipment. Compactness, versatility, versatility, high productivity, optimal cooking time, simplicity and perfection of design are invaluable advantages of this technique.

Unlike a conventional oven for baking bread, a convection oven is equipped with several fans with reversible movement. They are a favorite in combination with powerful heating elements. To buy a convection oven means to be sure that your pastries will always turn out perfect, without unbaked middles or burnt places. The circulating currents of hot air guarantee an accelerated cycle of baking bread, as well as an even distribution of temperature throughout the volume and at each level of the baking cabinet.

Convection oven: how to buy the right one?

The range of convection-type cabinets ranges from entry-level to ChefPro. Before you buy a convection oven, you should determine the required performance of your workshop and the necessary functionality. This will help you choose the model with the best price-practical ratio.

Industrial convection ovens for baking bread can withstand heavy loads. Housing made of high quality steel alloys; hardened, heat-resistant outer and inner glass doors; carbon fiber handles guarantee quality and reliability of the construction. The professional gas convection oven can withstand rapid temperature changes (from 30 to 300°C) and constant mechanical stress. Such an oven can work throughout the working day and even around the clock! A continuous production cycle will help you optimize your bakery 100% and increase profitability.

Prices for convection ovens are largely due to their options. Models vary in power and performance; dimensions; the number of levels under the baking sheets (from 3 to 20), the sizes and the distance between them; control (mechanical, touch); type of energy carrier (electric, gas); the number of functions. From 10 to 100 built-in programs in professional ovens with convection will help you not only bake flawless loaves, but also cook pizza, meat, fish, grilled chicken, tobacco chicken, side dishes, defrost or reheat various dishes.

A convection oven with steam humidification will provide the necessary humidity, preserve all the best qualities and taste of products. Advanced functionality will give additional comfort: grill function - golden brown; connection to the water supply together with the cleaning system - automatic washing; additional timers - simultaneous cooking of different products, etc. The "COOL" function will drastically reduce the temperature in the chamber and is especially useful for bakeries with a lack of production space. Finished products can be forcibly cooled and immediately packaged. Convection confectionery ovens with the function of blocking the arbitrary opening of the door can be placed directly in the supermarket trading floor. The smell of fresh baked goods attracts even more and persuades visitors to buy.
