  • the air flow is controlled manually by means of the control system.
  • the control equipment will selectively vary the effective size of the air valve openings.
  • the control equipment regulates the temperature by varying the oxygen supply. Because the control equipment is in an easily accessible location, this operation is very easy to perform.
  • the temperature in the tandoor device can be regulated by operating the air valve.
  • the air valve comprises at least one opening, preferably at least two and in particular at least three openings, wherein each opening has an air supply surface between 1900 mm 2 and 2800 mm 2 , preferably between 2100 mm 2 and 2600 mm 2 and in particular between 2300 mm 2 and 2400 mm 2 .
  • the air valve supplies fresh oxygen and can be manually operated via a control system.
  • the temperature is substantially regulated by the air valve. If the air valve is fully opened, the oxygen will be optimally added to the fuel through the air channel, which increases combustion and increases the temperature, until the fuel has burned up. If the air valve is closed more, the oxygen supply will be cut off, the fuel will receive less oxygen, combustion will decrease and the heat will decrease.
  • the temperature can be regulated via the air valve control system, preferably between 100°C and 300°C. These temperatures are good enough for any type of dish and preparation. When preparing thinner pieces of meat or fish, the air valve must be fully open. Slow cooking of food is also possible and will take place at a temperature between 100 and 150°C, with the air valve being more closed.
  • the chimney element comprises a hollow space that preferably has an oval shape, wherein an open base includes a first dimension and an open top includes a second dimension greater than the first dimension wherein a cross-section of the chamber increases as a wall extends downward from an upper end, wherein the base is provided removable from the barrel.
  • the device Due to the highly insulating effect and the slightly oval shape of the device, it has a temperature of up to 500°C inside the device and the temperature will be uniform. This means that food is cooked very quickly and does not have time to lose moisture and nutrients.
  • the chimney element is partly closed, preferably by a lid. It is important that the chimney element is partly open during the preparation of food. Too little discharge of burnt gases to the outside with a large quantity of fuel causes the wrong type of smoke in the device. This smoke will penetrate the meat, affecting the taste. This often results in a bitter taste. This smoke is gray and opaque.
  • the chimney element is made of a metal material, preferably aluminum.
  • the chimney element is made of metal, preferably the chimney element is made of aluminum.
  • the chimney element can also be made of another fire- and heat-resistant material, for example from ceramic materials, enameled with a heat-resistant glass-like finish or from a combination of metal and ceramic materials.
  • the thickness of the chamber wall has an almost uniform crosssection, so that the outer surface of the wall facing the environment, i.e. the outside air, is generally parallel to the inner surface. Due to the highly insulating effect and the slightly oval shape of the device, temperatures can reach up to 500°C inside the device. This means that food is cooked very quickly and does not have time to lose moisture and nutrients.
  • the material from which the tandoor device is made preferably metal, ensures good heat circulation.
  • the open top of the chimney is suitable for providing a removable ring wherein one or more notches are provided along the entire inner circumference where it is suitable to provide one or more skewers in an inclined, but generally upright position.
  • the length of the skewer is equal to the height of the chimney between the top and the base of the chimney, wherein the skewers are provided upright above the fuel.
  • the bottom ends of the skewers will rest on the fuel and with the top ends of the skewer resting against the removable ring with notches.
  • the recesses of the ring will hold the skewers in place so they don't shift.
  • the advantage here is that food skewers cook very evenly and also faster than on a grill. Due to the even cooking, the upright position in the chimney, the skewers no longer have to be turned while the food is cooking, so constant monitoring of the food is not necessary. Food will burn less quickly, be ready faster and retain its taste and juiciness better.
  • the tandoor device comprises a barrel assembly and a chimney element, with a height ratio of at most 1 :2, preferably at most 1: 1.6 and in particular at most 1 : 1.2.
  • the tandoor device forms a closable oven.
  • the temperature is the same everywhere in the oven. Thanks to this property, the food does not burn, but is, as it were, saturated with heat and is cooked from the inside. Due to the voluminous size, the temperature in the tandoor device drops no earlier than 1.5 to 2 hours after lighting the fuel. This makes it possible to grill a wide variety of dishes in any order and thus provide a large group with different grill specialties in just a few minutes.
  • the food is prepared at a constant, even temperature.
  • the invention concerns the use of the tandoor device for preparing food, preferably in the open air.
  • tandoor device Before using the tandoor device, fuel, pyrogenic material, is placed on the grate, wherein the chimney element is removed. The pyrogenic material is then ignited. The chimney element is then placed on top of the fuel.
  • the food to be prepared for example meat, fish, etc., which may have been previously soaked in a marinade, is placed on metal skewers with heat-insulated handles. These skewers are then inserted through the open top of the chimney element to rest with their bottom on the fuel. In a slightly inclined but generally upright position, the skewers lean against a ring with notches that rests on the top of the chimney, with the handles of the skewer protruding from the top of the chimney element.
  • the heat from the burning material is conducted along the metal skewers to cook the food internally, while the radiated and convected heat from the fuel is delivered to the outside of the food to cook it, and additionally to flavor it when the fuel is of an aromatic nature.
  • the metal skewers can optionally be hollow throughout most of their length to improve heat transfer from the heat source to the food placed on them.
  • the tandoor device can also be used as a conventional barbecue or grill. This involves adding a baking grid to the barrel assembly and removing the chimney element, with the food being placed directly on the baking grid.
