Cutting set system for a meat mincing machine

A cutting set system for a meat grinder, comprising a knife journal (10, 10′), the knife journal being drivable, and having a cutting element mounted on the knife journal (10, 10′), the knife journal (10, 10′) having a cross-section and

• wherein the knife journal (10, 10′) has a bearing section (13) for the cutting element mounted on the knife journal (10, 10′),
• wherein the cutting element has a central hub (21) provided with a through hole (22) for rotationally fixed mounting on the knife journal (10, 10′), the through hole having a cross-section and having an inner surface, the cross-section of the knife journal (10, 10′) being configured to the cross-section of the through hole of the cutting element,
• wherein a plurality of partial circumferential surfaces (151, 152, 153, 154), form a circumferential surface (15) of the knife journal (10, 10′), interacting as drive surfaces with partial inner surfaces (231, 232, 233, 234) of the inner surface (23) of the through hole (22) of the cutting element during a rotational movement in a direction of rotation (D),
• wherein at least one coding is present on the inner surface (23) of the through hole (22) of the cutting element and on the circumferential surface (15) of the knife journal (10, 10′),
• characterized in that either:
• the coding of the knife journal (10, 10′) acts as a journal-side coding element (14, 14′) between adjacent partial circumferential surfaces (151, 152) and, in a coordinated manner, engages with a coding element (24, 24′) on the cutting element between two adjacent partial inner surfaces (231, 232), or
• the coding is arranged on a partial circumferential surface (151, 152, 153, 154) of the knife journal (10, 10′) and matches to a corresponding coding element on the cutting element;
• the coding further characterized in that the coding on the inner surface of the through hole and the coding on the circumferential surface of the knife journal each have a respective cross section, and still further characterized in that there is only a single way for the two cross sections to match, whereby any rotation or juxtaposition of the two cross sections other than in the single matching way will fail to match.
