Abstract: A hydraulically powered separator includes a separation chamber, an auger, a restrictor ring mounted at an output end of the chamber, a hydraulic cylinder having a reciprocating ram, a proportional hydraulic valve operatively coupled to the hydraulic cylinder, and a controller operatively coupled to the proportional hydraulic valve so as to control the hydraulic cylinder in a closed-loop manner. The chamber receives and processes a food product and has a cylindrical screen including a plurality of apertures. The auger is rotatably disposed within the chamber and an annular space and a volume is defined between the auger and the screen. The restrictor ring can be linearly and reciprocally displaced. Linear displacement of the restrictor ring varies a size of the volume. Movement of the ram causes pivoting movement of the restrictor ring to reduce or increase the size of the volume.

Abstract: Separation chambers, deboning machines, and methods of operating the same are provided. In one aspect, a separation chamber for a compression-type deboning machine includes a body defining an internal cavity therein having a frusto-conical shape. A central longitudinal axis of the body extends from a first opening of the cavity near a first end of the body to a second opening of the cavity near a second end of the body. The first opening is larger than the second opening. The separation chamber also includes a plurality of perforations defined through the body from an inner surface of the body to an outer surface of the body. Each perforation includes a perforation axis extending longitudinally through a center of the perforation. The perforation axes of the plurality of perforations are transverse to a radial axis extending perpendicular to the central longitudinal axis of the body.
