ABSTRACT:
The invention is concerned with an improved grinder useful for grinding meat, which grinder includes a first section for coarsely grinding the meat followed by a second section for more finely grinding the meat, the two sections including screws which are coaxial with each other and driven by a common power source. The improvement comprises a cylindrical section intermediate the coarse grinding section and the fine section, the intermediate section including a shaft coaxial with both of the screws and connecting one screw to the other with a chamber surrounding said shaft. The shaft includes two partial screw threads both of which have pitches greater than the pitches of the threads in the two grinding sections. The intermediate section serves to transfer meat or the like from the coarse grinding section to the fine grinding section at a rate such that the fine grinding section can effectively grind the meat into a fine grind while not becoming clogged and not tending to overload the common power supply for the overall grinding apparatus.
