Description:FIELD OF INVENTION
The present invention relates to a cooking apparatus and method of radiative cooking for food products. More particularly, the invention relates to a radiative cooking apparatus thereby providing a more efficient and precise cooking method that minimizes energy consumption, reduces cooking duration, and maximizes the retention of nutrients during the cooking process.

BACKGROUND
Cooking is an integral part of day-to-day life, not only limited to household purposes; but has also expanded tremendously on a commercial scale. All these domestic or commercial cooking workplaces rely on traditional cooking methods, such as those utilizing gas burners or electric coils, often resulting in uneven cooking and the loss of nutritional value in food. These methods rely primarily on conduction and convection, where heat is transferred from the heat source to the cooking vessel and then to the food. This process can lead to hot spots, overcooking on the outside while leaving the inside undercooked, and the degradation of nutrients due to prolonged exposure to high temperatures.
Furthermore, traditional cooking methods can be energy-intensive and time-consuming. Gas burners, for example, release a significant amount of heat into the surrounding environment, leading to wasted energy and increased kitchen temperatures. Electric coils, while generally more efficient than gas, can still take a considerable amount of time to heat up and cook food thoroughly.
PRIOR ARTS:
KR101287834B1 discloses a cooking apparatus using magnetic resonance and a method thereof, wherein at least one magnetic resonance circuit is provided in each of the magnetic resonance cooking apparatus and the cooking vessel, and energy is generated by using the magnetic resonance generated in the magnetic resonance circuit. By producing and cooking with the generated energy, it is possible to solve problems such as adverse effects on health due to radon gas or harmful gas, harmfulness of electromagnetic waves, etc. It can be done safely.
CN103460795A discloses a method and apparatus for applying laser energy to a food product to effect cooking thereof. The energy can be applied with a laser emitter in proximity to the food product. The application of the energy can be controlled according to a profile so as to generate a plasma in and around the food product during a cooking period. The application of energy can be adjusted based on feedback associated with the controlled application of the energy to the food product.
Further, EP2055216A1 discloses a radiation cooking device comprising a cooking surface for receiving a food to be cooked, and a heating device placed above the surface where a vertical opening is extended from the surface. The heating device has a reflecting system surrounding an electrical resistor and comprising openings wherein the reflecting system is arranged with respect to the cooking surface and the resistor such that heat radiation from the heating device forms a heat curtain, whose width is equal to width of the cooking surface.
Although the prior arts relate to different alternatives of cooking methods and devices, none of the aforementioned prior arts address the various problems of uneven cooking, undercooking, loss of nutritional value, more energy and time consumption. Owing to these drawbacks, there exists a need for a more efficient and precise cooking method that minimizes energy consumption, reduces cooking duration, and maximizes the retention of nutrients during the cooking process. Thus, the present invention provides an all-in-one solution to the existing problems of the traditional cooking appliances, by employing radiative cooking principles to provide a superior cooking experience.

Another object if the invention is to provide an apparatus and method of radiative cooking for even cooking and breaking down the food at a molecular level, thereby retaining its nutritional content.
Yet another object of the present invention is to provide a cooking apparatus which is utilizes radiation as the primary mode of heat transfer.
Yet another object of the present invention is to provide a cooking apparatus which is only consuming only 1/6th to 1/10th of the energy required by conventional LPG-based cooking methods.
Yet another object of the present invention is to provide a mid-infrared radiation has the unique ability to penetrate food, exciting the water and organic molecules within the food and causing them to vibrate and generate heat.
Yet another object of the present invention is to provide a cooking apparatus which is designed for energy efficiency, the energy loss to the surrounding environment is minimized and results into significantly lower energy consumption compared to traditional cooking methods.

SUMMARY
The present invention relates to a radiative cooking apparatus thereby providing a more efficient and precise cooking method that minimizes energy consumption, reduces cooking duration, and maximizes the retention of nutrients during the cooking process; comprising of IR unit Assembly, SS cup sub assembly, SS base cup assembly, carbon brush sub assembly and vessel; wherein the vessel utilizes a carbon printed glass as the base; which when connected to a power source, the carbon printed on the glass emits mid-infrared (IR) radiation; that penetrates the food, promoting even cooking and breaking down the food at a molecular level, thereby retaining its nutritional content. The apparatus is designed to operate with extreme energy efficiency, consuming only 1/6th to 1/10th of the energy required by conventional LPG-based cooking methods. Additionally, the mid-infrared radiation emitted by the carbon printed glass is specifically tuned to interact with the molecular structure of food, promoting the breakdown of complex molecules and the retention of essential nutrients. This leads to healthier and more flavorful meals, as the natural flavors and nutritional value of the food are preserved.
The cooking apparatus is also designed for energy efficiency. By directly heating the food through radiation, the energy loss to the surrounding environment is minimized. This results insignificantly lower energy consumption compared to traditional cooking methods, making the invention an environmentally friendly alternative.
