The machine can also be equipped with 2 knives and 2 holeplates operating with Iozzelli 'extermination" grinding system (knives turning twice as fast as grinding screw): this way it's also possible to easily process rind as well as mincing meat for finely ground sausages such as mortadella. A short knives stud allows to use these machines as a standard grinder having knives turning at the same speed as grinding screw.
