FIELD OF THE DISCLOSURE
The present disclosure relates to an apparatus for heating or cooking ingredients.
BACKGROUND OF THE DISCLOSURE
Cooking is the art and craft of preparing food for consumption. It can also be said that cooking is the practice or skill of preparing food by combining, mixing and heating ingredients. Cooking involves a lot of influence from science as well as an eye of an artist and that is why has been a field of constant innovation. In the process of cooking, a user usually requires ingredients to be cooked, vessels, heating or cooking apparatus and fuel. More often than not, in rural areas, the user specially uses open fire cooking and mud stove, which may exhibit characteristics like compatible to wood fueling, cheap, widely available, requires no skill and so forth.
Whenever the user has to choose a heating or cooking apparatus, he/she is left over with lot of conventional apparatus. These conventional heating or cooking apparatus may be effective in meeting various requirements but may not be able to address some of the specific problems. For example, there may be the conventional heating or cooking apparatus which may consume less wood for effective heating at the cost of high pollutant emission. As a result, the user may use less wood fuel to heat or cook the ingredient, but may inhale lots of pollutants. Further, there may be the conventional heating or cooking apparatus which may produce less pollutant emission at the cost of less efficiency. As a result, the user may have to spend more for the fuel wood to restrict heavy pollutant emission. Furthermore, there may be the conventional heating or cooking apparatus which may only be utilizing some amount of heat generated in the heating or cooking apparatus. As a result, most of the heat generated in the heating or cooking apparatus may get wasted. Furthermore, there may be the conventional heating or cooking apparatus able to heat and cook only one ingredient at a time. As a result, the user may not be able to heat or cook two ingredients at a time. Furthermore, there may be chances that while heating and cooking the user may touch the outer wall of the conventional heating and cooking

apparatus accidently. As a result, the user may get burned.
Accordingly, there exists a need to overcome shortcomings of the existing the heating and cooking apparatus. For example, there exists a need of a heating and cooking apparatus which may consume less wood for effective heating along with controlled pollutant emission. Further, there is need of such heating and cooking apparatus which may produce less pollutant emission and deliver high efficiency. Further, there is need of such heating and cooking apparatus which may recover waste heat and utilize it for secondary purposes. Furthermore, there exists a need of such heating and cooking apparatus which may heat or cook two ingredients simultaneously. Furthermore, there exists a need of such heating and cooking apparatus which may provide some level of safety from burns if the user touches the wall of the heating and cooking apparatus accidently. In this way, the user may be able to heat or cook ingredients at much lower expense and with less carbon emission.
