NEXT GENERATION’S ENERGY AND TIME EFFICIENT NOVEL PRESSURE COOKER

Cooking is a basic need in day to day life which makes it the world's most energy consuming sector among all others utilizing 30% of the total energy consumption of the world. Cooking is a physicochemical process and it requires thermal energy. Therefore it is need of the hour to make the cooking practices more thermal efficient. In this research work, a novel heat transfer phenomenon occurring while the cooking process is in progress was observed and on the basis of the observed phenomenon designing principles of energy and time efficient cooking device has been proposed. Till the present time, it was considered that in cooking phenomenon, as the heat gets supplied externally to the cooking device, the temperature increases and eventually cooking goes in progress. But in this newly invented cooking device, this phenomenon of cooking is distinctly different in which temperature inside the cooking ves- sels rises even after terminating the fuel supply. It is also observed that, as the heating is in progress and once the tem- perature of water reached up to 85°C for rice and 95°C for lentils then there is no need for further heat supply and sen- sible heat content inside the water is sufficient for carrying out further cooking process completely. The mechanism of heat transfer and fluid mechanics occurring inside the cooking volume in this innovative cooking device is co mpletely different from the existing cooking devices. In this novel cooking device, cooking gets initiated from the top of the layer and proceeds towards the bottom layer. Water required for carrying out the cooking gets trickle down from the top layer to the bottom layer. The science accountable for this naturally occurring phenomenon of heat transfer and fluid me- chanics has been taken into the consideration for the development of this novel technology and cooking device acceler- ates the cooking process with 70 to 80% saving of energy. This Next generation's energy and time efficient novel pressure cooker can solve two major environmental and economical problems: limitation of environmental pollution due to the burning of additional fuels and reduction of the fuel costs since the process requires relatively low consumption.
