Recently, on private plots, you can often find oriental ovens with an exotic name – tandoor. They are great for outdoor cooking and are sure to impress your guests. What is especially nice – such a device can be done by hand. How? Let’s take a closer look at this issue.!
How the tandoor works
To understand how the tandoor works, we will describe the process of its operation using the example of a clay version. This is one of the most popular variations of oriental stoves that are found in our area..
The air circulates thanks to the blower – a special hole in the lower part that supports combustion. It is in the Uzbek variety that the clay bowl is lined with refractory bricks. The main secret is to fill the voids between the brick and the walls of the clay bowl using sand or salt – this allows you to maintain the temperature for as long as possible..
Coal or wood is used as fuel. They are placed on the bottom of the boiler through the top and then ignited. Dishes are prepared using a wire rack or skewers.
The tandoor is made only from materials with a high ability to retain heat. After heating, depending on the selected fuel, the temperature can reach 250-400 degrees Celsius. Thanks to the right materials, this oven is able to maintain the temperature for 5-7 hours.
DIY brick tandoor
In this section, we will look at how to build a tandoor using bricks. This is a very simple option that does not require unconventional materials and skills..
Any type of construction work begins with careful preparation, since this is the key to a successful result. If you have experience in laying bricks, then the whole process will be quite simple for you. This is a fairly simple construction, but if this is your first time with masonry, then you should carefully read the construction algorithm and prepare all the necessary materials.
First of all, you need to calculate the required amount of material or use ready-made schemes, which are accompanied by estimates. We have prepared for you a standard instruction and a list of required materials. So, first you need:
1. About 100–150 kg of a mixture of sand and gravel;
2. Mesh for reinforcement – about 2 sq. M .;
3. 7 kg of cement (use a higher quality one);
4. 60–70 pieces of fireclay bricks;
5. Fire-resistant mixture for laying fireplaces or stoves – 10-15 kg;
6. If you are going to paint the tandoor, purchase a fire-resistant paint.
When all the necessary materials have already been prepared, make sure that you have the necessary set of tools. Most likely, most of the items from the list presented can be found at your dacha or asked from neighbors, but even if you have to purchase something, it will not ruin you. To build a brick tandoor with your own hands, you need the following tools:
– Plastering rule (preferably along the length of the base);
– A bucket or other container to mix concrete;
– Putty knife;
– Paint brush and paint container;
– Grinder, as well as stone circles.
As you can see, the list is not very long or exotic. Preparing all the fixtures will not be too difficult for you..
For a long service life, the tandoor needs a very reliable foundation. It is he who will give a stable position to the entire building. Despite the fact that this is not a very heavy structure, a lot depends on the soil. For example, if it contains a lot of clay, then the base needs to be strengthened..
If the ground cover in your area is heavy, use pole-based supports. In the case of lighter soil, for example, sandy, it is necessary to first fill in a concrete slab on which the furnace itself will be located.
Based on our scheme and the prepared materials, the area of the entire tandoor will be 100×100 cm.To maintain a structure with such an area, a concrete cushion with a thickness of at least 10 cm will be enough.
Correct and good concrete looks like thick gray sour cream. To prepare it, you need to adhere to the following proportions: 3 portions of sand, 1 portion of gravel with a fraction of not more than 1 cm, 1 portion of cement. If you stick to these recommendations, you will get a great mixture..
Try to correctly calculate the required amount of concrete mix, for this you can navigate by the size of the pit for pouring the slab. Build timber formwork for a level base. Cover the bottom of the hole with a layer of sand about 5 cm, then pour water over it. The sand serves as a damper cushion, which has a positive effect on the durability of the building. Follow all recommendations and you will get a level and correct concrete slab for your foundation. Remember to use a level to keep the base of your structure as flat as possible..
Concrete sets not earlier than three days after pouring. The correct decision is to let it brew for about a week, and only then continue the construction of the tandoor. If the weather is hot and dry during the laying of the foundation, then be sure to periodically treat the concrete with water so that it does not dry out and crack..
The base of the tandoor
Refractory (fireclay) brick is an option that should be preferred, it does not absorb liquid, and also withstands very high temperatures. In turn, the density of this material allows it not to collapse under the weight of the entire structure..
Another advantage of choosing this brick is its resistance to sudden changes in temperature. That is why you should use it to build a tandoor on the street. This species copes with frost, and it is also quite safe to light it up in winter and use it for its intended purpose without fear of the integrity of the building..
Lay the base in a circle, first laying roofing material under it. Lay out the bricks, then mark them and cut them with a grinder until they are in the desired shape. Use only fire retardant mortar for laying bricks.
Rule for masonry
When following the rule to start laying walls, you need to take into account a number of features. The right solution would be for the base to be equal to the height of the entire tandoor, and the ratio of the base to the upper neck is 1 to 3. If you are making a stove based on our size recommendations, then use a bar of wood with a height of at least 1 m to make the rule, because the length of the base of the rule will be 30 cm.
For the production of patterns, as a rule, use plywood. Painted or varnished plywood is ideal.
In our example, the bricks are stacked vertically, so you will need quite a lot of mortar. Install the inner edges of the tandoor as tightly as possible to keep the walls as tight as possible. Do not forget to thoroughly work out all the seams with mortar, you do not need to save on strength.
Use steel wire or reinforced mesh to reinforce the entire structure. If using wire, then reinforce each row. In the case of a reinforced mesh, you can do with just one turn of it in a circle..
When you have completed the basic structure, you can move on to the plaster. This must be done using the same oven mixture. Try to make the thickness not less than 10 mm.
Wait until the plaster is completely dry, for safe drying, you can wrap the structure with a film.
The dried structure can be painted over. You can apply fireproof acrylic paint or whitewash. Also, to decorate the tandoor, you can use decorative plaster, and only then – paint.
DIY clay tandoor
Next, we will describe step by step instructions for building a tandoor using clay. This is a more complex and time consuming method of making a furnace. Before proceeding to its construction, try to study the issue and think about whether you need a clay copy. It is worth noting that the main and, perhaps, the only difference from the brick version is the ability to bake cakes on clay walls..
The classic dimensions of a clay tandoor are: height from 1 to 1.5 m, diameter – about 1 m, top – 50 cm. To form a clay bowl, use a mixture of kaolin clay and camel or sheep’s wool. When all the materials are ready, go to work.
Cut the wool 1–1.5 cm and mix with the clay. You need to knead it to the consistency of thick gray sour cream. To keep the clay strong and durable, leave it in a dark place for about a week. During the entire holding time, remove excess moisture from the surface of the clay, but at the same time it must remain moist. Otherwise, when operating the tandoor, it will crack.
To form a tandoor, it is necessary to prepare sheets of clay mixture with a thickness of about 5–10 cm. Further, in traditional production, they mold the bowl of a furnace from them, but this method requires skills and considerable skills. If you are not ready to take risks and do everything traditionally, a barrel can help you..
When using it, you need to loosen the hoops and pour water. Leave it on for a week to swell. This will give it the necessary shape for making a tandoor. Drain the water, dry the barrel completely, and treat the walls with butter from the inside. When it has absorbed a little, you can move on to using the mold. We advise you to prepare the mold and the clay mixture at the same time..
Making a tandoor from clay
At this stage, it is already possible to start forming a tandoor in a mold, or to roll sausages with a diameter of no more than 5–7 cm and a length of up to 1 m from a mixture of clay, and already form a furnace from them. This does not play a big role, the main thing is to understand how it is more convenient for you.
Place the clay firmly on the sides of the barrel, then coat and join the seams with your hands or a trowel. Collect all walls of the stove, but do not cover the bottom. The narrowing of the upper part should reach ½ of the entire diameter of the barrel.
When you have fully formed the shape of the oven, smooth the clay all over the inside. It should be as smooth as possible. Now leave the oven to dry.
Once the clay has dried, it will calmly lag behind the walls of the barrel. Take off the hoops, disassemble the barrel and take out the tandoor.
Place the oven on a prepared clay, concrete or refractory brick site. It must have a hole for air circulation, the so-called “blower”. Connect the oven and base with the same clay and let dry..
Already in this form, your personal tandoor is ready to use, but if you want it to keep the temperature as long as possible, you should cover it with a brick, and fill the resulting gap with sand or clay. This design will be able to maintain the temperature for 5-7 hours..
