ABSTRACT:
A meat grinder wherein the meat discharging end of the barrel for the rotary feed screw is separably connected with a tubular member having an extension which is remote from the barrel and is provided with a lateral meat evacuating opening. A star-shaped meat tearing or ripping member is installed in the tubular member upstream of the evacuating opening and has a bearing for the rear end portion of a shaft the front end portion of which is connected to a transverse front end wall of the extension. The latter is surrounded by a tubular element which has a lateraly opening and is rotatable relative to the extension to move its opening to a position of greater lesser register or overlap with the opening of the extension and to thus vary the rate of discharge of meat from the tubular member. A disc-shaped baffle is mounted on the shaft adjacent the opening of the extension and is movable to any one of several different positions axially of the shaft. The rear end portion of the shaft is surrounded by a plastic sleeve which is installed upstream of the tearing member and further receives the front end of the shank of the feed screw in the barrel.
