ABSTRACT:
An apparatus and method for a meat deboning machine are disclosed of the type which includes a drive motor with a motor shaft, an auger for conveying meat and bone material product, and a motor coupling for coupling the auger to the drive motor shaft. A housing surrounds the auger which includes a feed can having an inlet into which the product is fed to an entry end of the auger, and a sieve screen through which the meat passes radially to separate from the bone material. The auger includes two sections consisting of a feed auger and a compression auger which have a continuous taper and flights when coupled together as a single auger. The flights have an increased depth, to receive more product with reduced cavitation and pressure. The inlet of the feed can feeds only a single entry flight of the auger so that product does not back up into the feed opening. The root of the auger has a taper of about 9.degree. so that a deep entry flight is provided at the entry end which can receive more product than is capable of being fed to the auger. Both the feed auger shaft and the compression auger shaft are provided with slidable couplings so that no threads are used. The feed auger section and the compression auger section are advantageously machined from a one-piece stock of tool steel so that the root and flights of the auger are one piece. This eliminates welds and enhances the sanitation of the auger.
