Extracts for barbecue and barbecue. How to make a hood for the barbecue yourself? Extraction for barbecue in metal gazebo with own hands: drawing

Many are interested in how to make a hood for the barbecue with their own hands. Before you start to make the device, experts advise you to decide what type of oven you will use. For each species there is a different configuration of the chimney.

The brazier, executed by own hands, has the unified design of the rectangular form, the bottom part of which is equipped with apertures. When cooking food, the heat comes not only to the bottom of the device, but also to its walls. The air that gets through the holes is not enough for frying food, so the coals have to be fanned. This causes the spread of smoke in all directions. Therefore, the extract for the barbecue should be twice as large as the product itself.

What can you do homemade hoods?

The extract for the barbecue, made by own hands, can be metal or brick.

The brick structure is suitable for stationary type adaptation. Metal chimneys have become more widespread. They have the shape of a dome and are mounted directly above the grill. Both hoods for barbecue and barbecue have their pros and cons.

• Devices made of metal have a higher level of functionality. But such devices require constant care, as they are susceptible to corrosion. Particles of rusty metal can get into food.
• Brick chimneys are distinguished by their durability, but it is rather difficult to build them. In addition, such a design inherent cumbersomeness.

When choosing a hood, consider the type of barbecue used and the area of the room in which it is located.

Making of a drawing from a brick

The basis of this design is a frame made of corners. It is attached to the back of the brazier. The first row of bricks is laid perpendicular to the wall, and the rest are parallel.

Typically, a brick hood contains ten rows. The last row should be exactly as large as a hole for smoke. The diameter is regulated by means of a special valve. Above the exit of the pipe is mounted a visor.

What tools will be needed?

To make a brick hood, you need to cook:

• level;
• Rope;
• Plumb bob;
• Master OK;
• Container for mixing the solution.

When constructing a chimney for a fixed type mangal, attention should be paid to the quality of the brick. This material will be heated, so it must have sufficient strength to sudden temperature changes. Accordingly, for a chimney it is better to purchase a special brick for furnaces, which is designed for specific temperature regimes.

Proper kneading of mortar for masonry

When preparing mortar for laying bricks, one must adhere to the correct proportion of sand and clay. The ratio should be 3: 7. To have the chimney laid out by you has a long life, it is better to use a solution based on clay, which has a fireproof property. But if such a material is difficult to obtain, then ordinary clay soaked in water can be used. It is necessary to ensure that sand and clay are mixed thoroughly. The mass should fit well on the smooth surface of the brick and do not roll down.

Extraction of metal

An extractor for the barbecue in the gazebo with its own hands is installed provided that the roof of the structure in the area of docking with the pipe is made of refractory material.

As a rule, the chimney has the form of a truncated cone or it looks like a canopy in the form of a dome. In the center it is equipped with a hole, which receives air polluted from food preparation. The edges of the holes are connected to a vertical pipe, the height of which is 3 m. The exhaust pipe exits the center of the roof.

Extraction for barbecue in the form of a dome has a diameter of 1.5 m. The umbrella is mounted on racks or suspended from the ceiling by arbors on the chains. The back of the chimney must be equipped with a small bend. Professional masters call it "tooth". This design contributes to a better smoke output. Over the hood should be mounted a special protective cap, which prevents the ingress of sediments into the pipe.

Metal hood for the barbecue with their own hands is made of sheet material 2 mm thick. If there is not one, then you can take another sheet metal. The perfect choice will be copper.

The design of the umbrella should be smooth. Any unevenness helps to reduce the traction force due to the accumulation of fat and soot in it. These elements can block the chimney.

Remember that the opening of the device must fit snugly against the pipe. Asbestos for such a construction is not suitable.

The shape of the chimney must not necessarily be a dome. An extract for a barbecue in a metal gazebo can be in the form of a cone, a rectangle or a square.

For the production of skills required to work with sheet material, as well as owning riveting skills.

What will it take to work?

In order to make such a device, you need to prepare:

• The Bulgarian;
• meter;
• a hammer;
• Apparatus for welding;
• Riveting tools.

If you do not have the experience of working with metal, it is better to resort to the simplest configuration in the form of a truncated pyramid. During installation, do not allow it to come into contact with a gas pipe or electrical wiring.

Advantages of metal products

The extract of metal has its advantages:

• Simplicity of installation;
• Ease of maintenance;
• Possibility of use with different products;
• Aesthetic appearance;
• Affordable price of the material.

Stages of manufacture

The following algorithm should be observed:

• Drawing drawing of an extract for a brazier is selected;
• Material is selected;
• Parts are prepared;
• The blanks are joined by welding and riveting;
• The chimney is mounted on special racks or fixed to the ceiling by means of chains;
• The device is coated with a special material against rusting;
• Trial use of the device is performed.

Extraction for barbecue of portable type

It is often problematic to cook shish kebab in the street. For example, you may not be able to do this because of bad weather. The output is the placement of a barbecue in the courtyard of a private house or an arbor. Many can not build the hoods described above. In this case, it is advisable to resort to assembling the simplest design intended for a portable type of brazier.

What do you need?

In order to make a device such as a barbecue hood with your own hands made of metal, you will need:

• Steel corners 3 mm thick;
• Sheets of steel with a thickness of 0.7 mm;
• drill;
• Bulgarian;
• Rivets.

Sequencing

With the help of the Bulgarian, sheets of metal are cut.

From the steel corners is made the framework of the future design. In its form it looks like a hood for a fireplace, which is sold in stores. The size of it should be greater than the surface of the furnace both in length and width. Typically, the height of the device is 80 cm. In the upper part of the chimney is installed a hole for the pipe, which is outwardly guided.

Cutted steel sheets are drilled with corners and fastened with rivets. The height of the hood is selected in accordance with the ceiling height of the room in which it is located. Often the pipe is supplied with a deflector of a removable type. It helps to strengthen the traction force. The chimney is installed on the frame of steel corners or suspended on a chain.

Helpful information

If you decide to make a hood for the barbecue with your own hands, you should definitely know about what problems you may encounter when using it.

• When the furnace is ignited, the smoke is collected indoors and does not enter the device. The reason for this phenomenon can be that the smoke that appears is low in temperature. The density of it is the same as that of air, which causes no traction. The problem will be solved by itself, when the fire inflames and the temperature rises.
• The extract for the barbecue can not draw smoke from the room after the flame has flared up. If you are faced with this situation, it means that the chimney does not have the required cross-section. For a brick device made by one's own hands, the optimal index is 26X26 cm. A metal pipe directed vertically can be made narrower. Its diameter should be at least 15 cm. This will ensure good aerodynamics.
• The smoke that stretches out of the pipe rises not high enough. To avoid this problem, the pipe of the device is mounted in such a way that its upper edge is at a height of 3 m from the ground. This provides a high level of traction and good dispersion of smoke in the air.

Conclusion

It is generally known that the smoke generated by the combustion of coal or firewood emits poisonous substances. Therefore, being near a brazier that is not equipped with a hood is dangerous to health. A person can become dizzy. In addition, clothing is inevitably saturated with the smell of burning.

To avoid problems, the oven should be supplemented with a chimney. As a rule, it is made of metal. The extract for the brazier should be heat-resistant and not be corroded.
