There are several reasons why you may be having this issue:

  1. The meat is too warm – instead of cutting the meat the mincer is ripping the meat. Before you start to mince, put the meat into the freezer to chill – DO NOT FREEZE – only take out as much meat as you can grind at one time. Always keep the meat as chilled as possible.
  2. The knife is on backwards. Make sure the flat part of the knife is up against the mincer plate.
  3. The knife & plate are ‘Mix-matched’. ALWAYS use the same plate & knife as a matched set. If one has gradually worn away from perfect level – the other will have worn with it. If a knife is used with a number of different plates, the knife will start to wear out at different levels causing large gaps between the knife & the plate, once again ripping the meat rather than cutting the meat.
