Abstract: A comminuting machine for comminuting meat and the like and especially for material which has been previously cut into small pieces. The comminuting machine includes at least one cutting unit. A feed pump is arranged in front of the inlet of the comminuting machine and a vacuum suction device is connected to the interior of the feed pump. A separating device for solid objects, especially a separating device for ferromagnetic objects including at least one electromagnet, is mounted between the feed pump and the comminuting machine.

Abstract: A cutting unit for a comminuting machine, particularly for meat. The cutting unit includes a perforated disk and a drivable cutting knife body with cutting edges which interact with the perforated disk. The cutting knife body has additional cutting edges which extend approximately in radial direction. The additional cutting edges interact with approximately radially extending counter-cutting edges of the machine housing. The additional cutting edges may be provided in the form of grooves on the free ends of arms of a star-shaped cutting knife body. The counter-cutting edges may be provided on a housing ring which can be easily replaced and repaired. The additional cutting edges and the counter-cutting edges do not contact each other. The cutting edges preferably extend parallel to each other and are located on an imaginary outer truncated cone-shaped generated surface of the cutting knife body and an inner truncated cone-shaped surface of the machine housing.

Abstract: A pump, particularly, for pasteous masses, includes a rotatable outer wheel provided with a plurality of inner teeth, a pinion rotatable inside the outer wheel eccentrically thereto and having a plurality of outer teeth, the outer wheel and the pinion forming an intermediate space therebetween, a pressure seqment located in the intermediate space between the outer wheel and the pinion, an inlet and an outlet which are offset relative one another in direction of rotation, and a filling device connected with the inlet, the filling device including a filling container and a feeding element arranged in the filling container and having a feeding direction so as to feed a mass toward the inlet.
