Modern technical solutions allow you to cook meat in automatic mode. An example of this is electric grills. And there are several options for implementation. Let's consider in detail.
Why is it needed?
Those who often cook barbecue for several years can say that electric barbecues are not needed. And this is explained by the systematic attitude to the roasting of meat, on the coals the food is cooked in a push, as if it were ripening. Someone claims that turning over affects the taste, but in practice no one comparative analyzes did not produce.
For barbecue lovers, it happens that the outside is a good crust, but inside everything is raw. It is for these cases that an automatic brazier with an electric drive is provided. The electric drive for a brazier on each skewer allows:
- Produce an even roast. Thanks to measured turns, minimum loss juice. The meat is quite juicy and soft.
- No burning fat. Usually fatty meat just melts, dripping onto the coals. Hence the flame. The electric drive eliminates this.
- No need to do the same type of mechanical work. He can just keep an eye on the angle and the rate of rotation.
As a result, you do not need to constantly monitor the cooking process. You just need to buy a quality product, mix a good marinade and wait for your favorite dish to be cooked.
For already finished automatic barbecue you can buy a drive for skewers. It is inexpensive, but will not last long. And also many retail chains on warm seasons provide portable grills with electric drives, for example, Megagrill grill. The cost for 2018 is from 3.000 rubles. Yes, for some it is expensive. Therefore, we will try to assemble for the barbecue with our own hands from improvised means a simple circuit.
We'll need
Under the classic brazier with electric skewers, we get:
- electric motor,
- drill,
- grinder,
- pulley,
- belt or bicycle chain
- gears for the number of skewers.
As an engine, it is optimal to take an electric motor from a toy or a car drive.
Gears are sometimes machined, but more often just bought. It is better if all the details do not rust.
We carry out installation
We already put the system on the finished brazier for rotating skewers with our own hands.
The sequence is as follows:
- We install the engine.
- We fasten the gears at a convenient distance of 5-7 cm from each other.
- We stretch the chain so that the whole system sits tightly on it. It is desirable to adapt it last.
- It is more correct to fix the gears on a separate plate, and already install it to the barbecue box.
- The engine must be placed on its side from the outside. It is more convenient to weld fasteners (hooks) and hang the device on them.

How to put the gears right
Rotation will be ensured by the fact that gears are connected to each skewer. From one to the other, the skewers get the same speed.
When all the elements are mounted to the plate, you need to tighten the chain:
- From the very beginning they pull on the first gear and pulley.
- Then they move on to the second.
- Already after the chain is passed over to the third.
We get something like a snake from a chain or belt. And after correct installation such an element needs to be protected. Just a strip of steel or a triangular profile will do.
Purchased drive
Often two simple element for such a system it is impossible to assemble even under a skewer for barbecue. In order to avoid difficulties, we acquire finished types drive for skewers. Its classic type works from battery. It is clear that the battery rotation will be at a minimum speed. And visually it is such a device a nozzle that can be placed on any surface made of steel or brick.
The purchased unit is quite mobile, it is pleasant to take it with you on the road. Important feature in the possibility of adjusting the rotation speed. We have a built-in electric motor with a gearbox.
After a day of work spent on suburban area, people want to please themselves and loved ones with "sweets" in a hurry. Having built a brazier with an electric drive at the dacha with his own hands, the owner will get such an opportunity. Equipped with a mechanism for automatic rotation of the skewers, the brazier will not need constant attention.
Design features
The main disadvantage of traditional barbecues is that an experienced cook should be nearby all the time, who will make sure that the meat does not burn during cooking, because fire is the enemy of barbecue. The follower has to sit at the barbecue inseparably, soaking in smoke and inhaling fragments of soot.
Automatic adaptation solves many issues at once:
- Frees up time to spend on other household chores.
- The kebab is fried much more evenly than under the supervision of a person, without charring, the meat is more juicy and soft.
- By purchasing an additional grill with a spit, the device will be able to cook several dishes at the same time, saving time.
- The brazier with all accessories has compact dimensions, is easily disassembled, does not take up much space during storage.
- The device cleans up quickly.
This is interesting:how to make a skewer for barbecue with your own hands.
The only serious drawback is that there must be a power source nearby. It turns out that cooking can only be done near a residential building, from where it is easy to reach the carrying cord. But at a picnic in the forest or on the river bank, it will already be useless, unless you get an additional battery.
In addition, you will have to take into account the cost of electricity.
It is also worth mentioning the fact that, according to gourmets, barbecue prepared in this way differs in taste from roasted on a regular grill. But this, it seems to us, is a moot point.
Video "Barbecue with an electric drive with your own hands"
From this video you will learn how to upgrade the brazier and add an electric skewers drive to it:
Purchased electric drive
For those who are at odds with technology, it will be easier to purchase a ready-made drive in a store. This approach eliminates difficulties, moreover, a purchased electric drive is often supplied with a proprietary battery.
Structurally, the magazine drive is an ordinary nozzle that is easy to attach to any flat surface. The drive can be powered by batteries, however, the rotation speed will be minimal. Devices equipped with a speed controller are produced.
There are ready-made electric grills for sale. The meat is fried from the incandescent filament on vertically arranged skewers, the juice and fat flow into the recesses provided. The taste of shish kebab fried from a heating element really differs from meat cooked on fire, but you can use such a device even in a city apartment.
How to do it yourself
If you need a stationary brazier, it is easier to make it yourself. The device in this case can be massive. It provides a solid foundation.
The simplest device should include two main elements:
- Engine. It is removed from any unnecessary electrical appliance, a microwave oven or an electric toy will do. It is good if the engine is equipped with a gearbox that allows you to adjust the speed of rotation of the skewers.
- rotation mechanism. good decision will use an ordinary bicycle chain and several sprocket gears. Gears can be machined, but it is easier to buy, preferably with a coating that prevents rust.
The prepared materials will need to be fixed on a metal plate equipped with a shaft with bearings. The plate will be mounted outside the brazier; for this, bolts are provided in it.
Principle of operation homemade apparatus: the turned on motor will begin to rotate the gears, they will gradually transfer the torque to all the parts in turn, causing the skewers fixed in the holes to rotate.
To create such a device, you will need a drill and a grinder.
Don't forget about 2 main elements
Box making
Those who do not have the brazier itself will also have to make a brazier. Required for installation metal sheets approximately 3 mm thick. They are cut, then cut with a grinder to get the bottom of the brazier and four sides in the form of a rectangle.
Manufacturing takes place as follows:
- Each plate is fixed in turn in a vise, then they begin to drill holes with a diameter of 1 cm.
- In the walls they are placed at the bottom in increments of 3 cm. The heat from the coals will be drawn through them.
- At the bottom, holes are made with a smaller distance. They are needed for ash removal.
- All parts are welded into a box - the body of the future barbecue.
- In the upper part of the long sidewalls, recesses are drilled into which skewers will be inserted. The distance between the notches is equal to the width of the gear with a minimum tolerance of 0.5 cm.
Now it remains to "plant" the brazier on the legs.
Engine selection
It is desirable to select a motor with a power of 12 watts. You can borrow it from:
- power window;
- car wiper;
- microwaves;
- cordless screwdriver;
- replaceable timing phase;
- an outdated electric stove with a grill function.
More on initial stage it is worth deciding whether your motor will be powered by the mains, batteries or accumulator. However, one does not interfere with the other. By making the power supply universal, you can be powered from the outlet, staying with your family in the country, or from the battery, leaving the whole company for a picnic.
Assembly of skewers
To rotate, the skewers are inserted with their ends into the middle of the rotational gears connected together in common system. Two types of torque transmission from the motor shafts to the gears are used:
- Serrated. The mechanism is compact. Forms too hard transmission, makes a lot of noise. The transmission constantly has to be lubricated during operation.
- With the use of flexible elements. For this purpose, a bicycle chain, belt, thick tape or cord are suitable. Unfortunately, soft parts (belt, tape) can slip from time to time, and such a mechanism cannot be called durable. The device will turn out bigger size, it is necessary to take into account the increased load on the shafts and supports.
You can start the rotation from the central gear, which will begin to move the neighbors on both sides. Another option is to turn one of the extreme ones, it transmits the moment adjacent to it, etc. This mechanism makes the skewers rotate in one direction, so that the strung meat will not cling. The juice is also distributed more evenly, falling on neighboring pieces, making their surface more juicy.
When rotating in different directions, the friction force of the skewers against each other increases, which is why they can even fall out of the nests, i.e. the presence of a person will be useful. The gears are installed strictly perpendicular, even a slight misalignment can jam the mechanism.
Experienced cooks have noticed that the meat should receive the main portion of heat in the initial 2-3 minutes of cooking. To achieve this, it is desirable to heat it manually - first on one side, then on the other. As a result, a crust is formed that will not allow the juice to flow out. Only after that, the skewers are connected to the rotary mechanism of the electric grill and automatic uniform roasting begins.
There is probably no person who would not love a really high-quality vacation, but few people know how to create the conditions for this. During outdoor recreation, most people only do what they cook. most time, and then eat and really rest. Although almost the entire cooking process on the grill can be avoided, and only come on time and replace the skewers with new ones. And while a person is resting, an automatic electric drive works for him, which turns the skewer around the axis, so that the meat does not burn and is fully cooked.
Among all electric barbecues, it is better to choose one in the design of which there are heating elements inside the grill rods high power. This will allow the fat from the meat to caramelize, giving any dish a special flavor.

Mangal production
- Steel plates 4 mm.
- Welding machine.
- Drill.
- Corner 4 mm.
- Screws with nuts.
- Roulette.
- Dye.
There are many DIY variations, but the most commonly used classic version from steel plates, but in this case it will have to be slightly modified, because. additional mechanism will be used.
Do-it-yourself barbecue diagram: a - side view; b - top view (the lower grid is shown in section); in - the device of legs on castors; g - lid of the brazier (galvanized steel sheet 0.9 mm thick); d - scoop; e - fan; g - poker; h - skewer; 1 - handle with hooks (wire 010 mm from of stainless steel, 2 pcs.); 2 - under (kiln brick); 3 - brazier (steel sheet 4 mm thick); 4 - leg (pipe 03/4″, 4 pcs.); 5 - stock of firewood; 6 - longitudinal connection (pipe 01/2″, 2 pcs.); 7- cross member (pipe 01/2″, 2 pcs.); 8 - mesh (wire 02 mm); 9 - handle with a table; 10 - fan fan (duralumin sheet); 11 - fan handle (wood).
We need 2 pairs of plates, one of which will have a length of 30 cm and a similar height (if desired, you can add 5-7 cm), and the other with the same height has no formal length restrictions (each looks at its own discretion, depending on the number family members), 1 more is made from below for the entire area. The first are called transverse, the second longitudinal, the third - the lower. Interesting feature lies in the fact that one of the longitudinal plates will be 2.5 cm higher than the other, and under the very top it will have a series of holes with a diameter of 1.5 cm in order to fit any skewer.
Each longitudinal plate is installed in turn in a vise, and a series of holes are drilled in it with a step of 3 cm at the very bottom, after which the procedure is repeated in a checkerboard pattern 1-2 mm higher. Each hole should be 8-10 mm in diameter. These 2 rows of holes on each side will serve to supply air to the fire. For the same purpose, the bottom plate is also perforated, but not with the same frequency, but several times less often (at the discretion of the manufacturer). If desired, you can use a grinder and make oblong holes 5 mm wide and up to 50 long.
The next step is to weld together so that all the holes are on the bottom. But besides these holes, there should not be any other access to air (cracks, flaws).
The supporting system for such barbecues is created even easier than they themselves. To do this, the perimeter is surrounded by a corner and then it is welded - this will be the frame at the support. The legs can be made collapsible, or vertical ones can be welded from the same corner. If you are interested in a completely collapsible option, then a corner is taken, steel plates (fortunately, there will already be plenty of waste by this time) are welded to the bottom and top of the future legs. After that, the frame is drilled in the corners, and the plates on the legs in the center. After that, a screw is threaded into the hole and fixed on the side of the leg with a nut. In order to small parts not lost, they are fixed with paint in their places.

Electrical system
- Electric motor 12 V.
- inverter.
- Gears.
- Leather or metal belts.
- Soldering iron.
One brazier is, of course, very good, but it is much more pleasant if at the same time he himself is engaged in frying, and the task of a person during frying is only to replace skewers, and for this it is necessary to make and mount an electric drive. There are two ways to create a drive system - simple and complex, but in both cases a motor is used that is powered by 12 V.
A simple approach would require a motor and a step-down inverter. This design connects by means of a metal or leather belt and is easily mounted. The only negative is the manufacturing cost and the difficulty in finding desired part, because step-down inverter every year does not become easier to find. In addition, repairs can also be difficult if a person is not very versed in the mechanism, because. there are no such workshops in nature.
Although the entire automatic electric drive can be made with your own hands.
This will require only an elementary knowledge of physics and a memory of the design of a bicycle. The larger the main sprocket and the smaller the rear sprocket, the higher the speed will be with less effort, respectively, everything can be turned in the reverse order and gears can already be used. In this case, it will be difficult to find the lowest speed motor, fix the smallest gear on its original part, and the largest gear on the grill, to which a similar one is soldered.
After that, already in the workspace, the system is repeated again. Thus, with the help of 4 gears, it is possible to achieve a reduction in torque many times over and already in place to select the last gear, which will control the final speed.
The last option looks cumbersome only in the description, but in the end it will not be much more than a purchased inverter. An automatic electric drive for a barbecue made in this way will serve almost indefinitely, because. it will take no more than 10-20 minutes to repair it and its price will be a penny.
As a result, the kebab is cooked and slowly rotates over the coals with an electric drive, the owners have a rest from the heart, and one can only hope that no one forgot to charge the battery before the rest.
Device for rotating skewers “Shashlychnik”
The video shows the first inclusion of a brazier with electric skewers and rotating gears. A total of 8 skewers can be installed. It's completely homemade installation. The gears are made by hand from PTFE. 27 volt geared motor, can be powered by a 12 volt, 0.7 amp power supply. It consumes 350 milliamps, that is, it can be powered from simple adapters. Can be powered from a car battery from an uninterruptible power supply. At 6 volts, the speed will be 7 revolutions per minute. At 12 volts 10 turns.

You can see how evenly the frying goes. With gear transmission, the skewers rotate towards each other. Fluoroplastic gears are good because they make less noise than metal ones. They were made according to a preliminary pattern, with a shoe knife. Two matrices were made of duralumin, between which the fluoroplastic was clamped, then the gears were cut out. The second video shows it all.
Development based on the old barbecue
May holidays are coming soon. The weather will be warm outside. And this means that we will see our friends, relatives and loved ones more often. How can such moments be without a delicious kebab cooked on a fire. That's why. Let's make the simplest device that will rotate skewers while cooking barbecue. For the manufacture of the design, the author of the development took what was left of the old barbecue maker. These are gears, a motor that is powered by the mains AC voltage. All that needs to be done is to weld the frame from the corner and fix all the details on it.
The rotation of the engine is transmitted to a series of gears, each of which is attached to a skewer.
Convenience automatic design that the skewers are fried evenly on all sides.
Barbecue with rotating skewers
On the video, the mechanism for turning kebabs. Used 9 bicycle sprockets. The front axles were cut in half and sprockets were welded on. Holes are drilled in the axle. Pin installed. Motorcycle chain. The chain from the bike was unreliable. Engine from car wipers. In order for the skewer not to fall out, a protective bar is placed. The mechanism is secured with two bolts. It is impossible to say that the device is fully automatic, according to the author of the development. He turns over himself, but he has to regulate the fire himself. Barbecue fire is the enemy. Plus, the roasting is even, the kebab does not burn. The height of the skewers is adjustable. Voltage is supplied from the power supply from the PC. I took a 5.5 volt output.
Automatic spit for barbecue
We present to your attention a grill that will glorify you as an outstanding culinary specialist. To do this, you do not have to study special recipes and take culinary training courses. This model was developed by people who are tired of swallowing smoke and throwing envious glances at their vacationing neighbors. The innovative autonomous drive system ensures the rotation of the skewers without human intervention.
The brazier works from the power supply unit and provides automatic rotation of skewers. You can close the lid in which the pipe is installed and continue to cook a delicious smoky dish.
For more than fifteen years I have been frying shish kebab and other tasty treats on a folding grill, and it has always served me flawlessly.
But sometimes it’s not convenient to constantly be near the barbecue, and therefore the idea came up to make the skewers spin by themselves using an electric drive.
What came of it, see in this video:
The video shows how kebabs and other tasty treats are cooked on a self-modern grill with an automatic skewers rotation system.
In my "Lazy Barbecue" Set, something is made with my own hands "from scratch", something is bought and redone ..
To be frank, very handy device turned out, which really helps to get exactly that juicy and delicious barbecue which we all love so much!
And even friends who have stationary brick barbecues (in summer cottages and in private houses) often ask to take my set with them when they invite me to visit.
For information on how to make an electric drive for rotating skewers directly, as well as on finalizing the rotation mechanism itself, see the following video:
Attention! In the video, I use the XL6009 boost converter. But, in Lately converters began to come across that did not work correctly at input voltages below 3.6 V, and now I recommend using MT3608 DC-DC converters instead. Therefore, an external variable resistor will be needed for 100-200 kOhm.
