Abstract
A meat grinding assembly incorporating several features which enhance the ability of the assembly to collect hard material such as bone, gristle, sinew or the like, to prevent such material from being ground along with the meat. The grinder includes an orifice provided at the end of a tubular housing, with a rotating knife assembly located against the inner surface of the orifice plate. The orifice plate include a series of radially spaced large collection openings, each of which is provided with an outwardly extending ramped entryway. The entryways into the collection openings facilitate passage of the hard material thereinto. The knife assembly includes a series of knife holding arms which extend outwardly from a hub, with the arms being oriented non-radially to the hub. The knife arms are angled forwardly, so as to facilitate passage of material toward the hub during rotation of the knife assembly. The hub includes as series of collection pockets located forwardly of the knife arms, which cooperate with the ramped entryways to the collection openings to pass hard material into the collection openings. An improved structure is provided for mounting the knives to the knife arms. T…
