Mankind has a requirement to eat food for its growth and survival. In ancient days, man used to pick up the fruits and vegetables directly from plants or used to hunt for animals and eat them. With the discovery of fire, ancient cooking started in which man used to roast his food before eating. Today cooking of food has become a necessity for mankind.
Cooking or cookery is the art or practice of preparing food for consumption with the use of heat. Cooking techniques and ingredients vary widely across, the world, reflecting unique environmental, economic, and cultural traditions. Preparing food with heat or fire is an activity unique to humans. There are many methods of cooking, most of which have been known since antiquity. These include baking, roasting, frying, grilling, barbecuing, smoking, boiling, steaming, and braising. A more recent innovation is microwaving. The said methods are generally used by majority of people for cooking food. The cooking devices available today are compatible to these methods of cooking. These devices provide cooking method and consume cooking, materials compatible to each other which result in faster cooking rather faster meal preparation. But they do not cook meats using fresh ingredients which are typical to home cooked food which is both healthy and hygienic. These devices mainly shorten the period and complexity of cooking which mainly involves the usage of frozen or stored food which isn't quite healthy.
Although cooking is essential, it can't be done by all as it requires basic knowledge as well as skill of cooking. One should know the art of cooking to cook food. Moreover, in today's world many people face various obstacles in cooking food like time, dedication, knowledge, mastery etc. So they depend on others to cook their food, outsource their requirement or go to restaurants or hotels for eating. But in such cases one has to compromise on the quality, taste, quantity, health & hygiene, availability, cost etc. So with the help of technology, man has developed machines for cooking food based on his needs and requirements.
U.S. Pat. No. 4,450,757 describes an automatic machine for cooking food such as soup-paste, rice or pot herbs, in which a support structure with a base and an upper working plane is provided with an open cooking tank contained within the support structure above the base and below the working plane, a water entry duct and an exit overflow duct is provided, water is supplied to the tank at a predetermined temperature, and a water circulation is associated with the tank and housed within the support structure for circulating cooking water at a predetermined temperature through the tank for intermixing with the water supplied by the water supply to the tank, and the temperature of the water in the tank is maintained at a predetermined temperature while the level of the cooking water is maintained at a predetermined level and the water is forced to exit through the overflow duct for the removal from the cooking water in the tank of particles suspended in the water such as starch and scums through the overflow duct.U.S. Pat. No. 4,548,130 discusses an automatic food cooking, machine comprising, a frame supporting, a housing having an unobstructed opening with an adjustable heating surface at the bottom thereof. Mounted in the opening of the housing are a pair of spaced parallel endless conveyor chains supported on sprockets connected to a pair of spaced shafts—one driven by a motor, and one used for adjustment of conveyor chain tension. Mounted between these shafts are idler sprockets used to support the conveyor chain. A plurality of spaced angles are connected to the conveyor chains, and a retainer fastened to the spaced angle is used to secure each food basket comprised of a bottom, four sides, and a hinged lid. A sauce dispenser is supported by a bracket fastened to a slide rail at the top of the housing.

Although a number of automatic cooking machines are available in the prior art, they are mostly limited to or targeted at cooking specific types of dishes and most of them are semi-automatic i.e. in such machines, most of the work needs to be done manually. Such machines require the user's presence while cooking food. Those inventions in which manual presence is not essential, the machine cooks limited recipes and their working area is limited. Moreover, most of these machines aren't user-friendly in using, operating and cooking; and are bulky and so haven't got much market exposure. So a portable, fully automatic cooking machine, compatible to all cuisine and food preparation methods, having assistive attachments, compatible vessels and modules adding capabilities, is user-friendly and is controlled using latest technologies is the need of the day.
