Apparatus for processing vegetables, flours and for processing animal meat for the production of sausages, comprising along the central rotation axis (100), a plurality of movable components synergistically rotating along said axis (100) including:
- the actuation shaft (200), the auger (1) provided with an axial bearing (99), at least one knife (11) arranged in proximity to the outlet of the meat supplied to the auger (1) and said knife (11) being provided with a central portion (101) in which a faceted central seat (104) is obtained adapted to fit into the respective seat (71) present on the actuation shaft (200) and with a plurality of radial supports (103) all provided with at least one cutting surface (102) called cutting blade and having the thickness of said radial support (103) which is progressively reduced moving away from the center of the knife (11), said knife (11) being positioned inside the cutting group (55) so that its central portion (101) and specifically its central faceted seat (104) is stably maintained in the suitable grooved seat (71), present on the actuation shaft (200), by the pressure exerted on the central portion (101) of said knife (11) and specifically at the contact point (53), by the central support or bushing (51) said pressure being adjusted by screwing the nut (50) threaded on the threaded rod (52) in turn inserted in the end part of the same actuation shaft (200), said apparatus for processing foods and meat in particular being further provided with a plurality of fixed elements, situated around said central rotation axis (100), including a loading hopper (70), at least one first fixed disc (3) for drawing meat, stably positioned inside the cutting group (55) due to at least one spacer (60) in turn supported by the thrust bearing (21) and by the connection ring nut (20) positioned on the outlet end of the ground meat of the cutting group (55), so that the threaded inner profile (25) of said connection ring nut (20), is threaded on the corresponding thread (26) obtained on the outer face of the body of the cutting group (55) so that the screwing or unscrewing of said connection ring nut (20) directly adjusts the pressure exerted by said connection ring nut (20) on the thrust bearing (21) which in turn supports and stabilizes the fixed disc (3′) and said actuation shaft (200) being provided with at least one cylindrical projection (300) arranged along said actuation shaft (200) provided with at least one circular bearing (40), a pair of pre-loaded circular bearings (40), adapted to stabilize and discharge the forces acting on said actuation shaft (200) on the structure body (64), preventing it from deforming the knife-holder support (11), therefore, all the above mentioned devices are adapted to maintain the knife (11) and the corresponding fixed disc (3) in the predetermined position keeping a predetermined distance or pressure therebetween.
