DESC:FIELD
[0001] The present disclosure relates to the field of food processing systems. In particular, the present disclosure relates to a method and a system for operating a mixer grinder.

BACKGROUND
[0002] Mixer grinders are kitchen appliances designed for mixing or grinding food ingredients, such as fruits, milk, ice, etc. The mixer grinder typically consists of a base part having a vertically positioned powerful motor with a first coupling, and a jar located directly above the base. The jar has a rotatable blade assembly at its bottom with a second coupling driven by the first coupling.
[0003] In the mixer grinder, the food ingredients are placed inside the jar and the process of mixing or grinding is performed by manually actuating control switches of the mixer grinder, as there is no pre-setting done for mixing or grinding the food ingredients. Also, during mixing or grinding, a user has to hold the jar till the mixing or grinding process is over.
[0004] Further, a common type of jar is generally utilized for mixing or grinding all kinds of food ingredients. Because of this, the user has to constantly inspect the mixing or grinding by opening and closing the lid of the jar. This in turn increases the processing time for obtaining a final product.
[0005] Further, in case a large quantity of the food ingredients is kept inside the jar for mixing or grinding, the jar can cause overload on the motor and may allow the food ingredients to leak out. Also, due to the continuous mixing or grinding of a large number of food ingredients, heat may be generated inside the jar, because of which the user of the mixer grinder may not be able to hold the jar of the mixer grinder. Such operating conditions of the mixer grinder may lead to hazards for the user, reduce the life of the mixer grinder, and make the mixer grinder unsafe to use and handle.
[0006] There is, therefore, a need for a method and a system for operating a mixer grinder that eliminates the above-mentioned drawbacks.

[00063] Figure 3 illustrates another exploded view of the plurality of sensors 108a, 108b placed inside the housing 108 and the plurality of magnets 110a, 110b placed at the bottom of the jar 110.
[00064] In one of the embodiments, the system 100 for operating a mixer grinder 102 is executed or implemented in more than one operating modes. In a first operating mode, a user may operate the mixer grinder 102 using a user interface 104 of the display unit 106, where the user interface 104 prompts the user to select one of the preset automated operations of the mixer grinder 102. In a second operating mode, the user may operate the mixer grinder 102 by manually actuating the control knobs 116 provided on the mixer grinder 102. In a third operating mode, the system 100 may be operated remotely by accessing through a mobile/web application over a wireless/ wired communication network. The user may use an application interface of the mobile/web application to send the request for operating the mixer grinder 102. The user may select any one of the preset automated operations of the mixer grinder 102 in the mobile/web application. The wireless/wired communication network may be selected from the group of communication mediums that may consist of short-range, long-range, or Internet of Things (IoT) and a combination thereof.

FIRST OPERATING MODE
[00065] In the first operating mode of the mixer grinder 102 in accordance with an embodiment of the present disclosure, once the mixer grinder 102 is powered on, the plurality of sensors 108a, 108b preferably the Hall Effect sensors continuously sense for the presence and magnitude of a magnetic field via the sensor input module 120 configured to receive sensed signals from the plurality of sensors 108a, 108b mounted around a motor coupler positioned on a top region of the housing 108 of the mixer grinder 102, when the jar 110 is placed above the housing 108. Now, once the jar 110 is placed above the housing 108 of the mixer grinder 102, the sensors 108a, 108b generate an output signal that is a function of magnetic field density created by the magnets 110a, 110b. When the magnetic flux density around the sensors 108a, 108b exceeds a certain pre-set threshold, the effect sensors 108a, 108b detect it and generate the output signal.
[00066] The output signal is then transmitted by the sensors 108a, 108b to the identification module 122 of the system 100. The identification module 122 is configured to process the sensed signals generated by the sensors 108a, 108b to identify a type of the jar 110 placed above the housing 108 and retrieve a set of applications associated with the identified type of the jar 110 from a memory. The identification module 122 is further configured to convert the output signal into a digital signal and process it to determine whether the jar 110 is locked on the top region of housing 108 or not.
[00067] Once it is determined that the jar 110 is locked, the activation module 124 is configured to activate the user interface 104 of the display unit 106 present on the mixer grinder 102 to display the set of applications.

[00068] Once the set of applications is displayed, the user interface processing module 126 is configured to receive a first selection input from a user through the user interface 104, where the first selection input corresponds to an action of selecting one of the displayed applications. Then, the user interface processing module 126 is configured to process the first selection input to retrieve a list of ingredients and their quantities from the memory 120, following this the user interface processing module 126 displays the retrieved list of ingredients and their quantities on the user interface 104 to be added in the jar 110 by the user. Further, the user interface processing module 126 is configured to retrieve a set of textures from the memory 120 based on the added list of ingredients and their quantities, and then display the retrieved set of textures on the user interface 104 after a predefined time which is required for the user to add ingredients in the jar. Following this user interface processing module is configured to receive a second selection input from the user through the user interface 104, where the second selection input corresponds to an action of selecting one of the displayed set of textures, and then generates a control signal based on the first selection input and the second selection input received from the user interface 104, and finally transmit the control signal to a motor driver of a motor unit 118 to drive a motor coupler for operating the mixer grinder 102.
[00069] In an embodiment, the sensors 108a, 108b are arranged or distributed on the top region of the mixer grinder 102, with respect to the magnets 110a, 110b mounted on the base of the jar 110, in such a manner that the voltage generated by the sensors 108a, 108b can be processed by the identification module 122 of the microcontroller 112 to identify the type of jar 110 mounted or locked on the top region of the mixer grinder. In an example, the types of jar 110 may include but are not limited to, chutney jar, spice jar, dry jar, wet jar, blender jar, food processor jar, chopper jar, specialized jar, and so forth.
[00070] In an embodiment, the microcontroller 112 may include the memory to store identification information related to the types of jars, a set of prompting rules to prompt the user to select specific applications and/or textures for the identified type of jar, and a set of operating instructions to operate the motor unit 118 based on the identified type of jar and selected specific applications and textures. The memory may be present in the web/mobile application or in IoT-enabled devices that are connected to the system 100.
[00071] In an embodiment, as mentioned above, once the mixer grinder 102 is powered on and the type of jar is identified by the identification module 122 of the microcontroller 112, the user interface processing module 126 of the microcontroller 112 displays specific applications on the user interface 104 of the display unit 106. The user of the mixer grinder 102 may then select one of the specific applications including, but not limited to, coconut chutney, mint coriander chutney, coffee grinding, spices, ginger garlic paste, smoothies, chopping, mincing, and so forth. An exemplary list of specific applications for an identified jar is shown in Table 1.
