The Thomas Precision 3XDDHD Variable Flow Bone Separator is a heavy-duty, dual-drive separation system engineered for maximum yield, product quality, and operational flexibility. Built on a heavy-duty stainless steel frame with a heavy-duty pump hopper and solid machined pump feed auger, the 3XDDHD combines a 30 HP pump gearmotor with a 50 HP tapered compression auger gearmotor ó both independently variable speed ó giving operators precise, simultaneous control over feed rate and separation speed. The result is a machine that can be fine-tuned to the specific input product to maximize yields, manage calcium content, and minimize temperature rise. The 3XDDHD successfully processes chicken frames, pork, and beef bone-in product, and can also be used as a second-pass machine to recover additional yield from the refuse generated by high-speed separators.
