The meat grinder dependence screw rod's advances hopper box in raw material meat cuts in advance the board place, through screw rod's turning effort, causes the reamer and the orifice has the relative motion, thus slivers raw material meat the grain shape, has guaranteed the meat stuffing uniformity. the meat grinder main body uses the stainless steel manufacture reasonably, the equipment structure, the mechanical property stable reliable, the noise is small. This machine may twist cuts the fresh meat, the frozen meat. The user may act according to the technological requirement, the match different specification orifice, processes the ideal meat stuffing, satisfies the different meat product the processing need.
