FIELD: machine engineering.
SUBSTANCE: grinding machine contains a hopper for placing the material to be ground, a grinding section including a grinding head, an adjusting ring, a partition, a cylindrical part and a collecting pipe. In the grinding head, a feeding worm or screw is disposed to advance the material through the said head, and at the end of the feed worm a knife assembly rotating with the feed worm and the spinneret is installed. A collecting funnel is located behind the spinneret. The spinneret comprises a plurality of grinding holes and, at least, one collecting channel, the grinding holes having a sphere intersecting with a cylinder adapted to create a Venturi effect resulting from the acceleration of the said material with a corresponding pressure drop through the said grinding holes. The spinneret for the grinding machine comprises a plurality of grinding holes having a sphere intersecting with the cylinder, with the possibility of creating a Venturi effect that affects the moldable food product. The bone collector contains, at least, one hole having a sphere intersecting with the cylinder to create a Venturi effect. Herewith the bone collector may comprise a bone collector pipe consisting of a waste tube, a waste screw and an insert for separating a bone containing a sphere intersecting with the cylinder to create a Venturi effect.
EFFECT: possibility of obtaining the smallest cross-section along the meat cut.
