A double plate retrofit assembly for a meat grinder includes a centering pin adapted for insertion into a longitudinal bore provided in the feed screw of the meat grinder. Primary and secondary knife holder assemblies are adapted for mounting to the centering pin, and primary and secondary orifice plates are mounted adjacent the primary and secondary knife holder assemblies, respectively. Adapter mounting rings are employed for affixing the orifice plates to the end of the meat grinder. A spring washer mechanism is disposed adjacent each knife holder assembly for biasing the knife holder assemblies against the orifice plates to improve grinding performance. The amount of bias provided by the spring washers is adjustable by adjusting the position of the mounting rings.

Double plate retrofit assembly for a meat grinder

A hollow pin set in the downstream end of the auger of a conventional food grinder has a downstream end which protrudes to an accessible outside area of the grinder and a downstream - facing shoulder which bears against the upstream side of the knife assembly of said grinder, biasing said knife against a perforated plate. An inside pin or bolt passes through the hollow pin, threadably connected therewith, and has a downstream end which protrudes from the hollow pin and which is adapted to receive a wrench. The upstream end of said inside pin or bolt presses against a compression spring. Applying a wrench to rotate the downstream end of said inside pin or bolt changes the compression of the spring and thereby increases or decreases the bias between said knife assembly and the perforated plate which the knife is biased against.
