|---|---|
| Abstract | This invention relates to an improved construction of a tandoor comprising an inner wall made of mud, an outer insulated wall spaced from the inner wall, and such as to define a passage there between for the flow of hot gases, a liquified petroleum gas burner supported on the base of said tandoor and so as to allow the hot gases from said burner to flow in said space. |
| Full Text | FIELD OF INVENTION This invention relates to an improved tandoor. BACKGROUND OF INVENTION A tandoori roti is a special kind of bread made from the wheat flour (maida) using special oven known as Tandoor. Traditionally, such kind of chulla is made from mud in which either coal or wood is burnt as a fuel. Such kind of tandoor takes a substantial period of time of approximately 90 minutes for initial heating only after which one can bake the roti. This kind of traditional tandoor produces a large amount of smoke. It also produces a large amount of emissions, which are injurious for health. It is also very cumbersome to use such kind of tandoor. OBJECTS OF THE INVENTION An object of this invention is to propose an improved tandoor. Another object of this invention is to propose an improved tandoor which has emission levels quite low in comparison to the known tandoors. Still another object of this invention is to propose an improved tandoor which takes less time for initial heating in comparison to known tandoors. Yet another object of this invention is to propose an improved tandoor and wherein the operating costs are substantially low. A further object of this invention is to propose an improved tandoor which is ecofrineldy. A still further object of this invention is to propose an improved tandoor which is not attended with any health hazards. STATEMENT OF INVENTION According to this invention, there is provided an improved tandoor comprising of an inner wall made of mud characterized in that an outer insulated wall spaced from the inner wall so as to define a passage there between for the flow of hot gases and a liquefied petroleum gas burner supported on the base of said tandoor, which causes hot gases from said burner to flow in said space defining an annulus passage wherein the outer wall has an insulation. DESCRIPTION WITH REFERENCE TO ACCOMPANYING DRAWINGS; Further objects and advantages of this invention will be more apparent from the ensuing description when read in conjunction with the accompanying drawings and wherein Fig. 1 shows a sectional view of the tandoor of the present invention. Referring to Fig. 1, the tandoor 1 of the present invention uses mud as provided in the traditional tandoor. However, LPG gaseous fuel is used which is more eco-friendly in comparison to traditional coal, or wood fired tandoor. Tandoor 1 has an annulus passage 2 which carries the hot gas from a burner 3. The LPG burner 3 is supported on the base 4 of tandoor 1. Once ignited, the flame is established on burner 3, which produces very high temperature hot gases. These hot gases enhances the temperature of the inner surface 5 of inner wall 6 on which raw roti is placed is placed for baking. Innerwall 6 is made of mud and has spaced openings 7. An outer wall 8 has an insulation 9 which arrest the heat loss and hence enhances its thermal efficiency. Tandoor is placed on a metal casing as shown in figure 1. WE CLAIM; 1. An improved tandoor (1) comprising of an inner wall (6) made of mud characterized in that an outer insulated wall (8) spaced from the inner wall so as to define a passage (2) there between for the flow of hot gases and a liquefied petroleum gas burner (3) supported on the base (4) of said tandoor, which causes hot gases from said burner to flow in said space defining an annulus passage (2) wherein the outer wall has an insulation (9). 2. An improved tandoor as claimed in claim 1, wherein the inner wall is provided with spaced holes (7). |
