How convenient is the tandyr in the ground?

Imagine preparing meals in a conventional oven that is hidden in your backyard. That is the fundamental component of a tandyr, a centuries-old Middle Eastern and Central Asian cooking technique. However, tandyr’s potential for insulation and heating has drawn attention in addition to its culinary prowess. In this piece, we’ll examine the practicality of utilizing a tandyr underground and examine how well it works for cooking and home heating.

Fundamentally, a tandyr is a partially subterranean clay oven, frequently shaped like a dome. Because of the way it’s made, heat retention is effective, which makes it perfect for cooking food slowly over extended periods of time. Sandyrs were originally made for baking bread, but they have since changed to accommodate different cooking methods, such as roasting meats and simmering stews. This adaptability has raised questions about its potential uses outside of the kitchen, especially for home heating.

The thermal characteristics of a tandyr make it one of the most fascinating heating options. Tandyrs have the potential to be a sustainable home heating option by capturing the heat produced during cooking. Even after the fire has subsided, the thermal mass of the clay and its insulation from being buried help to hold heat for prolonged periods of time. Because of their innate efficiency, tandyrs are being experimented with as an alternative to traditional heating systems.

In addition, the idea of using tandyrs for home heating is in line with the public’s growing interest in environmentally friendly methods. Alternative heating options are growing more and more appealing as worries about energy use and carbon emissions grow. With their dependence on organic materials and renewable fuel sources like wood, tillyrs present a viable option for lessening the impact on the environment while still giving homes warmth and comfort.

Nevertheless, the viability of utilizing a tandyr for home heating may differ based on a number of factors, even with its possible advantages. Climate, soil type, and local laws are important factors in determining whether or not such a system is practical and efficient. For tandyrs to function as heating devices in a sustainable and secure manner, additional factors like maintenance, ventilation, and safety must be taken into account.

To sum up, the tandyr offers an intriguing fusion of innovation and tradition, providing not only a delicious culinary experience but also a potential answer to insulation and heating needs. Although its use for heating in the ground is still largely unexplored in many areas, continued study and testing show promise for its incorporation into environmentally friendly home heating systems.

Features of the design and the principle of operation of the tandyr

A type of hearth that can withstand high temperatures and heat up quickly is called a tandyr. Its design can take many forms, but the earth and ground jug shapes are thought to be the most common.

This type of oven is unique in that the refractory clay that makes up its inner layer heats up quickly when fuel is heated, allowing food to cook more quickly. The basic working principle is the same as any conventional oven found in any household, but the primary distinction is the distinct flavor that adds flavor to even the most basic of dishes.

Varieties of tandoor

The types of tandyrs can vary depending on the location, loading technique, and fuel type.

1. Ground – is a kind of jug-shaped vessel with a narrowed bottom and neck. At the bottom there is a blowhole, through which the degree of air supply is controlled, which affects the size of the flame in the hearth. Easy to transport from place to place, requires special storage conditions.
2. Earthen – half of the oven is submerged at the foundation level. Such an oven serves not only for cooking, but also for heating the dwelling during the cold season.
3. Gas and electric – used mainly in catering, where there is a need to cook a large number of traditional Asian dishes.
4. Vertical and horizontal – in the first case, the loading of products is carried out from top to bottom, and in the second as in a conventional oven. For the classic tandyr is used vertical loading.

Every tandoor operates on the same principle, which is the presence of an inner clay layer that is heated to carry out the heat treatment of food, despite variations in location and design.

In addition to baking samsa and shish kebab, contemporary catering businesses have modified the tandyr to prepare unusual foods like pizza, fish, fruits, and vegetables.

Pros and cons

Asian hearths have the following benefits:

1. Easy to operate – all you need to do is find and load wood, light it and wait for it to burn through to coals.
2. Easy maintenance and storage – the tandoor is allowed to cool down naturally, after which it is covered with a tarpaulin or moved to a room with optimal microclimatic conditions. Soot, which is formed during ignition, comes off independently under the influence of high temperatures. No need to clean the oven every time.
3. Cooking with benefits – the principle of cooking in a tandoor is to utilize the heat from the clay walls, which is considered one of the cleanest and healthiest methods of heat treatment.
4. Duration of operation – if the oven is properly constructed and cared for, the minimum service life is at least 25-30 years.
5. Preserving the juiciness inside the product, while creating a beautiful brown crust on the surface.
6. High efficiency, which reduces fuel costs.

The primary benefit of the tandoor, though, is that you can easily make it yourself for a minimal material cost. Even a novice can construct it because the construction principle is so straightforward.

However, keep in mind that there are a few drawbacks that could compromise the furnace’s performance:

1. High probability of burns – if you do not follow the safety rules, there is a possibility that the flame from the tandoor will harm your health. Also do not forget that the outer walls during prolonged cooking can get quite hot, therefore, it is important to use baker"s mittens or rags.
2. Risk of cracking of the inner clay layer – if the first ignition is not done correctly and the temperature in the stove rises to high values extremely quickly, the clay may crack. Over time, these cracks will enlarge and may cause the inner layer to collapse.
3. There is direct contact with fuel – cooking takes place in close proximity to firewood, so some particles of ash may well get on the food, which will negatively affect the taste of the finished dish.
4. There is a need to periodically clean the lower compartment from soot and burned-out wood, which requires the use of special equipment: a long-handled spatula and a poker.

There are a lot more benefits, so it makes sense to purchase this stove and assess each one for yourself.

The technology of building a tandyr in the ground from brick

It is imperative to segment the entire project into multiple phases prior to initiating construction.

1. Creation of a drawing and plan, where all the numerical values of the furnace parameters will be indicated.
2. Preparing a place and digging a pit of the required depth.
3. Calculation of the amount of material required and its purchase.
4. Step-by-step laying of bricks, exterior finishing.
5. First ignition.

In light of the above plan, let’s think about the most straightforward method for creating a tandoor in the ground.

Drawing and plan

Making a decision regarding the fireplace’s size is essential. Typically, they are 40 cm deep and 80 cm in diameter. These figures can be adjusted further if needed, but it’s important to account for increased building material consumption, time and labor costs, and other factors.

Site preparation

It is important to select a spot where there are no combustible items within a 2-3 meter radius of the tandoor because there is a chance that the flame will ignite above the oven’s level. This is particularly true for facing plastic and dried wood on trees.

Calculating the amount of material required

These materials are needed to construct the tandyr:

• fireclay brick (easier to lay than clay) – about 55 bricks based on the area of the bottom and the height of the structure;
• Basalt wool to prevent heat loss – 1-2 square meters. м;
• fireproof mixture for masonry – 63-65 kg;
• steel pipe for organizing the chimney and under-blower.

Remember the tool that will be used for the majority of the work:

• a bayonet shovel for digging and a scoop shovel for selecting the ground;
• bolgar;
• trowel;
• wooden mallet for leveling the brick level;
• trowel;
• pliers;
• machine.

During the task, additional instruments like metal shears might also be required.

The main work on laying bricks

Following the previous preparation and drying of the pit, the following steps are taken:

1. Laying the bottom with bricks – the bricks are laid on the fireproof mixture, which is kneaded taking into account the recommendations indicated on the package. Bricks are laid in 1 row.
2. Formation of the chimney – with the help of a bolgar in a metal pipe make two holes of rectangular shape. One hole at a distance of 10 cm from the bottom, the second – at 20 cm. The lower hole will form the chimney under-blow, the upper one – the hood.
3. Forming the base of the tandoor – one row of bricks is laid from the bottom. For a height of 35 cm it is 5 rows. All cracks are sealed with fireproof clay in one layer. Let it dry well for 3-5 days. It is not recommended to cover the tandoor.
4. The chimney is installed, inside which the prepared pipe is mounted. All joints are covered with clay.
5. The ground part is laid out, which can be covered with facing bricks in the future.
6. The top cover is made in the form of a dome. It is easiest to take an ordinary metal lid from a large pot, as forming a clay dome will require certain knowledge and skills.
7. After the first clay layer dries up, it is necessary to apply the second layer of refractory clay with the help of a spatula and let it dry well.

Make the first ignition once the tandyr is prepared. Its goal is to assess the strength of the clay layer and the air supply system.

It’s clear from examining the in-ground heating system’s convenience that this age-old technique has special benefits for insulation and heating. Tandyr is a centuries-old method of producing and storing heat through the burying of a clay or metal vessel in the ground. It originated in Central Asia.
