    [0001] PROCEDURE TO CONTROL THE FORCE PERFORMED BY A USER ON A FOOD PROCESSING MACHINE
    [0003] The present invention refers to a method to control the force made by a user when processing food in a food processing machine, the food processing machine being of the type that includes a motor body housing an electric motor, a shaft of rotation that allows the activation of a processing tool associated with said axis, processing accessories attached or detachably coupled to the motor body and processing tools that, together with the accessories, are used for operations related to food processing, such as such as cutting vegetables, bread crumbs and the like, as well as a pusher to put food in contact with the processing tool.
    [0005] More in particular, the invention refers to a method for controlling the force made by a user when processing food in a food processing machine that allows the user to be informed, by means of a visual and / or acoustic element, of the force. that you are doing when you are working on a food processing machine, the visual and / or acoustic element also indicating the force that the machine is exerting, derived from the force that the user and the processing tool are exerting, and the maximum endurable force by the processing machine in order not to exceed the capacities of the motor.
    [0007] In the current state of the art, apparatus and machines are known that are used for operations related to food processing, such as cutting vegetables and vegetables, grating bread, emulsifying food and others of an equivalent nature. In general, the known machines of the aforementioned type consist essentially of a closed motor block inside which driving means are housed, a rotating shaft that emerges from the motor block and food processing accessories associated with processing tools, whose structural characteristics depend on the specific application for which they are intended.
    [0009] For example, in documents U201100576 or ES2253994 processing machines of this type are described.
    [0011] In particular, among the accessories and processing tools of the machine it is worth highlighting those intended for cutting or grating food.
    [0013] The appropriate accessory for this case is generally formed from a container in the lower part of which the cutting or grating tools are housed, as well as a pusher element that allows, on the one hand, to close the container accessory where the product is introduced. treat and, on the other hand, press or keep these products in permanent contact with the cutting or grating tools by means of a pusher. Thus, the force exerted by the machine is the sum of the cutting or grating force plus the force exerted by the products against the cutting or grating tools thanks to the pusher.
    [0014] The force exerted by the products against the cutting or grating tools is created by the user and transmitted to the user by the pusher, which normally manages it by providing pressure on the food against said tools. Consequently, the characteristics of the product obtained are directly related to the force exerted by the user with the pusher.
    [0016] This is a problem in obtaining a uniformly processed product . Thus, for example, if you want to grate cheese to obtain a grated cheese always of the same size and thickness, different users should always be able to exert the same force on the pusher, which is not possible, since different users they will apply different forces to get the final product. Since many restaurant chains want their products to always be the same, this is they want the standardization of their products to serve the same product in all their establishments, the fact that the result depends on the user is a great disadvantage.
    [0017] Therefore, it would be desirable to have a procedure applicable to a food processing machine that allows standardizing the processing result obtained in order to obtain a uniform processed product.
    [0019] In figure 1 a food processing machine is schematically shown according to an embodiment of application in the grating of a food, the processing tool being a grating disk.
    [0021] The present invention solves the aforementioned disadvantages of conventional food processing machines, providing a method to control the force made by a user when processing food, adaptable to a food processing machine, informing the user of the force that he performs. the machine and the force that it is exerting with the pusher, thus being able to control this force and obtain homogeneity and reproducibility in processed foods.
    [0023] For this, the process of the invention includes the steps of:
    [0025] - providing a food processing machine of the type that includes a motor body housing an electric motor, a rotating shaft that allows the actuation of a processing tool associated with said shaft, processing accessories detachably attached or coupled to the motor body, and processing tools that, together with accessories, are intended for operations related to food processing, as well as a pusher to bring food into contact with the processing tool,
    [0026] - constantly measure during the processing operation the intensity of current consumed by the electric motor, to know the workload carried out by the motor and
    [0027] - transmit to the user through visual and / or acoustic indications the work load carried out by the motor, to know the force that the motor is exerting and, therefore, to be able to exert more or less force with the pusher to obtain a homogeneous product.
    [0028] Thus, when the motor is performing a food processing operation, it is consuming a current intensity, the current consumption being proportional to the force that the motor is making, so that the more intensity it consumes, the more force it is making. This intensity can be read in the method of the invention by means of a measuring system such as an ammeter or equivalent.
    [0030] Thus, the workload carried out by the motor, in one embodiment, is transmitted to the user by means of a visual indication, for example by means of a progress bar, on a display screen, which can be present on the processing machine itself or constitute a separate element of it.
    [0031] In another embodiment, this engine workload may also be transmitted to the user by acoustic indication, for example by a sound of varying intensity or pitch.
    [0033] In a third embodiment, both visual and acoustic forms of transmission of the engine workload to the user are employed.
    [0035] Optionally, the method of the invention includes the step of previously defining the desired work load to be carried out by the motor and warning the user by means of a visual and / or acoustic indication that said load has actually been reached during a processing operation. .
    [0037] An advantage derived from the method of the invention is that the user can know if the food processor is being forced to work at a higher intensity than recommended. Since the force to be exerted by the machine depends on the force exerted by the user with the pusher, sometimes the user exerts so much force that it causes an excessive workload for the motor, causing effects such as stops due to overheating or premature deterioration of the components.
    [0039] Thus, the method of the invention optionally includes a step of notifying the user by means of visual and / or acoustic indications when the workload of the motor exceeds a recommended level and considered safe for the components of the processing machine.
    [0041] Examples
    [0043] The invention is described in more detail below based on an exemplary embodiment thereof, illustrative and non-limiting of the invention.
    [0045] As shown in Figure 1, the food processing machine has a motor body (1) housing an electric motor (2), a rotation axis (3) that allows the operation of a processing tool associated with said axis, accessories process (4), in this case a collection container, attached or detachably coupled to the motor body and a processing tool (5), in this case a grating disk, which, together with the accessories, are intended for operations related to food processing, in this case the grating of a food, as well as a pusher (6) to put the food in contact with the processing tool (5).
    [0047] During the grating of the food, the user presses it against the grating disk (5) with a force, defined in Figure 1 as F user . When the shaft rotates, the tool grates the food with a force defined in Figure 1 as F grater . Thus, the workload carried out by the motor corresponds to a combination of F grater and F user . The motor generates this force by consuming a current intensity , which increases in proportion to the increase in the force that the motor must carry out.
    [0049] During processing, the intensity of current consumed is measured, for example by means of an ammeter suitably arranged in a control element (7) in the motor body. The measurement collected in this control element (7), for example a control plate, allows the calculation of the workload carried out (F grater + F user ) and this workload is transmitted to the user through a visual indication, by example by a progress bar or circle on a display screen.
    [0050] For example, the visual indication may consist of a semicircle divided by blue and red bars, each bar representing a workload, capable of being illuminated. The more force the user exerts, the more bars will light. In this way, the user can know the workload carried out and can adapt to always work at that level of workload.
    [0052] Likewise, when the user is carrying out the operation of grating the food, if the workload of the motor reaches a predetermined level, in this example an acoustic indication is emitted to indicate that it is working at the chosen load level.
    [0054] In both cases, if the user keeps the workload level at the same level indicated by the visual and / or acoustic indications, the processed food obtained, in this example grated, will be of uniform size and thickness.
