Separation chambers for deboning machines

A separation chamber for a compression-type deboning machine, the separation chamber comprising:

• a body defining an internal cavity therein having a frusto-conical shape, wherein the internal cavity has a first opening near a first end of the body and a second opening near a second end of the body with the first opening being larger than the second opening;
• and
• a plurality of perforations defined through the body from an inner surface of the body to an outer surface of the body, wherein each perforation includes a material inlet defined at the inner surface of the body and a material outlet defined at the outer surface of the body;
• wherein the material inlet and the material outlet associated with one of the plurality of perforations are angularly offset from one another with respect to a radial axis extending perpendicular to a central longitudinal axis of the body.

A compression-type deboning machine comprising:

• an auger adapted to rotate and including at least one flute, wherein the auger is adapted to move meat connected to unwanted material from a feed end of the machine toward a discharge end of the machine upon rotation of the auger;
• and
• a separation chamber defining a plurality of perforations from an inner surface of the separation chamber to an outer surface of the separation chamber, wherein the inner surface of the separation chamber defines a frusto-conical cavity that is adapted to receive the auger therein, wherein each perforation defines a perforation axis extending longitudinally through a center of the perforation, and wherein the perforation axes of the plurality of perforations are transverse to a radial axis extending perpendicular to a central longitudinal axis of the separation chamber;
• wherein the flute of the auger is adapted to cooperate with the separation chamber to separate meat from unwanted material by moving meat and unwanted material through the separation chamber with the meat passing into and through the plurality of perforations transversely to the radial axis and the unwanted material moving through the separation chamber along the central longitudinal axis of the separation chamber toward the discharge end.
