There are many food processors and cooking appliances which are very sophisticated. But the limitation is mainly about the food that can be cooked and also the required quantity of ingredients that has to be put in the collection boxes for cooking. In an earlier pending application for patent for an electrically operated automatic food making machine, invention claimed has different boxes for ingredients. A recipe card is used to select the type and quantity of the dish to be cooked. The machin'e automatically collects the required ingredients and cooks the dish. However; the different south Indian recipes are not possible to be cooked in that food processor machine.

For instance, there are few US patents on food processors. Among them there is one device which describes about a cooking appliance coupled to a power supply having a cabinet provided with heating assembly having electrical heating elements positioned in the cabinet. Heating element system is a cumbersome process. They lack the provision of automatic collection of required ingredients from the bins /boxes which houses large quantities in them.

In another US food processor model there is provided a multi-purpose cooking appliance comprising a cooking chamber, a heat conductive pan within the cooking chamber/a heat source connected to the heat conductive pan; elongated skewers for supporting food within said cooking chamber and a tray. The said heat conductive pan and skewers do not exist in the applicant's food processor unit and it does not function like the cooking process of the food items prepared by the applicant's food processor.

In yet another US food processor model there is provided a cooking unit that is remotely controlled based on information relating to the object to be heated. The " information is transmitted to the appliance's computer from a management's computer. The cooking appliance can also locally cook any part of food in the cooking chamber. The said remote controlled cooking controller does not exist in the applicant's food processor unit and it does not function like the cooking process of the food items prepared by the applicant's food- processor.

In yet another US food processor model there exists a cooking appliance using rapid cook technology with an automatic electronic controller that converts conventional cooking temperatures input to rapid cooking temperatures. The said controller uses this temperature as the actual cook temperature for the cooking cycle for convection baking mode. The said rapid automatic electronic temperature controller does not exist in the applicant's food processor unit as it'does not take part in the cooking process of the food items prepared by the applicant's food processor:

In another model there exists a modular grill cooker that is easily installed in
r
a multipurpose cooking apparatus, including an outer casing and an inner casing placed in the outer-casing. The inner casing is provided with a heating unit to provide heating. Grilling unit is provided on a frame housed over the upper edges of the inner and outer casings. Contact terminals are provided on the outer casing and on the cooking apparatus to supply electricity to the heating unit to the grill cooker provided in the cooking device. However, there is no provision of automatic collection of required ingredients .from the boxes housing large quantities. The grilling unit and heating unit does not exist in the applicant's food processor unit as it does not take part in the cooking process of the food items prepared by the applicant's food processor.

In yet another US food processor model, there is provided a.self-contained cooker and cooking grill with four doors quadrilateral along with a separate cooking

grate attached to each door. A conventional barbecue type cooker or smoker with a full sized grate and a common area for burning of solid fuels. The operator has the facility to change cooking times as.regards the multiple door cooker and cooking surfaces can be heated differently for cooking the dishes. Each door is independently openable allowing the operator to access the immediate, cooking surface without disrupting the other cooking surfaces. The multi door grilling unit and heating unit does not exist in the applicant's food processor unit as it does not take part in the cooking process of the food items prepared by the applicant's food processor.

Description of the electric components:
i) Bins: A screw rod (11) fixed at the bottom portion of the bin, to dispense out of the filled ingredients from the bin. (Image shown in Fig 5)

i) Motor: 12-volt DC Metal gear motor (2), to drive the screw rod (11) of the bin.

ii) Hopper (4): A container which tapers downwards the ingredients from bin
(1) to the cooker (7). (Image shown in Fig 6) < .

iii) " Solenoid valve: 12-volt DC solenoid(21) for oil dispense from oil .tank (6)

iv) Pump motor (20): To pump the water from the water container(8).

v) Stirrer: To stir the ingredients in the cooker when in need. (Image shown in
Fig 7)
vi) Cooker (7):,To cook the dish.

Operation of the machine:

At first the bins (1) should be filled with the below mentioned ingredients for the
dish by the user before using the machine.

The ingredients are Cashew nut, Dry grapes, kesari powder, turmeric powder, salt,
pepper, mustard, cumin seed, Chana Dal, Rava, sugar, rice, moong Dal and cut
vegetables.

Fill the oil in the oil tank (6) and water in the water container (8).

Plug the power cord of the machine to the socket and switch it ON. At first the lid
(9) of the cooker (7) and stirrer (5) gets reset to its set position (i.e. in open
position). Then the display shows the default option KESARI.
User can select, the dish within the given option. After selecting the dish, press
"Enter" to start the process. (The sequence of the operation for each dish is shown
as flow chart.)
The ingredients will be collected automatically in the cooker (7) from the bin (1)
through hopper (4). After getting collected in the cooker (7), the stirrer gets down
into the cooker (7) to stir and the stirrer moves up to its position. Then the lid (9), of
the cooker (7) gets closed for cooking. After cooking, the lid (9) of the cooker (7)
gets opened automatically and the dish is ready to serve.

Stirring:
The Stirrer is set of assembly with screw rod (13) & screw rod motor (14) for
up/down movement and another stirrer motor (12) connected with a stirring.blade
(16) to stir. (Image shown in Fig 7). In this Automatic Food Maker, the taste will
remain same for every time we cook. The taste will not get varied since the entire
ingredients ratio is programmed. The ingredients ratio can be also set as per the
users taste.

Explanationof the Block diagram
The 230volts power supply is given to the electronics PCB board. The PCB is designed to control the motor of the bins (1), solenoid valve (21), submersible-pump, motor (20), motor (17) & motor (18) of cooker lid (9) and motor (12) & motor (14) of stirrer and the heater of cooker, the sequences of the ingredients and the logics of control are programmed using "Embedded 'C program in PIC microcontroller".

A feedback circuit is made to control the motor for lid & stirrer to be set to its -reset position while the machine was switched 'ON' at its initial time.

When the blade (16) of the stirrer (5) lifts up from the cooker (7), it will reach the holding plate (15) and close the limit switch placed at the bottom portion of the holding plate (15). Then the cooker lid' (9) will get opened (by moving backward position from the cooker). When the lid (9) of the cooker (7) gets opened fully the swing motor (17) shaft will close the limit switch of the feedback circuit. When the signal from both Lid and Stirrer feedback unit is received the control enters into the process. If the signal.is not received from anyone of the feedback unit, (i.e., the switch does not get closed) the control will not enter into the process. This feedback unit is made to ensure that the Stirrer is lifted up from the bowl and Lid (9) gets opened from the cooker (7) at every sequence of its operation.
