A meat grinder according to the invention comprises a housing, at least one conveying device for conveying material to be ground from an inlet opening to an outlet opening, and at least one cutting-unit part arranged in the housing. At least one transponder is arranged in or on the at least one cutting-unit part and at least one communication device for communicating with the transponder is arranged in or on the housing in such a way that data exchange between the communication device and the transponder is enabled. ## Claims ### Claim 1 A meat grinder having a housing and at least one cutting-unit part which is arranged in the housing, wherein at least one transponder is arranged within the at least one cutting-unit part which is arranged in the housing, and at least one communication device for communicating with the transponder is arranged within the housing, in such a way that an exchange of data between the at least one communication device and the at least one transponder is made possible, wherein the at least one communication device is connected to an electronic circuit or machine controller, wherein the at least one communication device interrogates data relating to the cutting-unit part and initiates action by the electronic circuit or machine controller based on the interrogation, and wherein at least a first anti-rotation element is arranged or formed in the housing, and a corresponding second anti-rotation element is formed in the at least one cutting-unit part, in order to arrange the cutting-unit part secured against rotation in the housing, and a first of the at least one communication device is arranged in the first anti-rotation element, and a first of the at least one transponder is arranged in the second anti-rotation element. ### Claim 2 (depends on 1) The meat grinder as claimed in claim 1, wherein the first anti-rotation element is a sliding block, and the second anti-rotation element is a groove which corresponds with the sliding block. ### Claim 3 (depends on 1) The meat grinder as claimed in claim 1, wherein the meat grinder has at least one of the following: a second of the at least one transponder inserted in a first opening formed in the cutting-unit part, and a second of the at least one communication device inserted in a second opening formed in the housing. ### Claim 4 (depends on 3) The meat grinder as claimed in claim 3, wherein the first opening and the second opening are arranged opposite one another. ### Claim 5 (depends on 1) The meat grinder as claimed in claim 1, wherein at least a first of the at least one communication device has means for transmitting data to the at least one transponder, and means for receiving data from the at least one transponder, and is connected to an electronic circuit and/or a machine controller. ### Claim 6 (depends on 5) The meat grinder as claimed in claim 5, wherein the electronic circuit and/or machine controller comprises a test module for carrying out safety-relevant and/or functional test procedures including the at least one transponder. ### Claim 7 (depends on 1) The meat grinder as claimed in claim 1, wherein the first communication device is arranged in the region of the outlet opening. ### Claim 8 (depends on 1) The meat grinder as claimed in claim 1, wherein in addition at least one of the following features is present: (a) at least one transponder is arranged in an outer region of a cutting-unit part, (b) a display is provided for a user for function-relevant and/or safety-relevant information determined by means of the communication device and transponder, (c) the arrangement of the at least one transponder in the cutting-unit part, and of the at least one communication device in the housing takes place in such a way that a cutting-unit part which is not inserted correctly in the housing can be detected on the basis of the relative position of the transponder with respect to the communication device, and (d) a read-only memory and/or a telecommunication device are/is provided. ### Claim 9 (depends on 1) The meat grinder as claimed in claim 1, wherein the at least one transponder is arranged directly opposite of a location of the at least one communication device. ### Claim 10 (depends on 1) The meat grinder as claimed in claim 1, wherein there is no metal located between the at least one transponder and the at least one communication device. ### Claim 11 (depends on 10) The meat grinder as claimed in claim 10, wherein there is no solid element located between the at least one transponder and the at least one communication device. ### Claim 12 (depends on 1) The meat grinder as claimed in claim 1, wherein the meat grinder is arranged to have at least one conveying device for conveying material to be ground from an inlet opening to an outlet opening. ### Claim 13 (depends on 1) The meat grinder as claimed in claim 1, wherein in addition at least one of the following features is present: a) the at least one cutting-unit part is arranged on a drive shaft of a conveying device for which the drive shaft is secured in the axial direction by means of a union nut, and b) the housing is arranged to partially mount therein, partially opposite at least one cutting-unit part, a conveying device that is a screw conveyor connected to a drive shaft or formed on a drive shaft. ### Claim 14 A meat grinder comprising: a housing; and at least one cutting-unit part arranged in the housing, including at least one transponder arranged within the at least one cutting-unit part, wherein at least one communication device for communicating with the transponder is arranged within the housing in such a way that an exchange of data between the communication device and the transponder is made possible, wherein at least a first anti-rotation element is arranged or formed in the housing, wherein a corresponding second anti-rotation element is formed in the at least one cutting-unit part, in order to arrange the cutting-unit part secured against rotation in the housing, wherein a first of the at least one communication device is arranged in the first anti-rotation element, and wherein a first of the at least one transponder is arranged in the second anti-rotation element. ### Claim 15 (depends on 14) The meat grinder as claimed in claim 14, wherein the first anti-rotation element is a sliding block, and the second anti-rotation element is a groove which corresponds with the sliding block. ### Claim 16 A meat grinder comprising: a housing; and at least one cutting-unit part arranged in the housing, including at least one transponder arranged within the at least one cutting-unit part, wherein at least one communication device for communicating with the transponder is arranged within the housing in such a way that a wireless exchange of data between the communication device and the transponder is made possible, wherein the at least one transponder is arranged within the at least one cutting unit part opposite the at least one communication device for communicating with the transponder arranged within the housing, wherein there is no metal located between the at least one transponder and the at least one communication device, and wherein at least a first anti-rotation element is arranged or formed in the housing, and a corresponding second anti-rotation element is formed in the at least one cutting-unit part, in order to arrange the cutting-unit part secured against rotation in the housing, and a first of the at least one communication device is arranged in the first anti-rotation element, and a first of the at least one transponder is arranged in the second anti-rotation element. ### Claim 17 (depends on 16) The meat grinder as claimed in claim 16, further comprising: a first opening formed in the cutting-unit part within which a second of the at least one transponder is located; and a second opening formed in the housing within which a second of the at least one communication device is located, wherein the first opening and the second opening are closed by non-metallic materials that are safe with respect to foodstuffs.
