FIELD: process engineering.

SUBSTANCE: invention relates to extrusion equipment used in food industry and production of extruded mixed fodder. Proposed extruder-mincer comprises housing with screw, sizing die, shaft and blade. Note here that mincing chamber accommodating rotary shaft is coupled with said die. Said shaft carried mandrel with its taper part entering extruder die, cross-like blade and two wavy vanes. Comb mincers are fitted on tail of one of the vanes and bush is secured to tail of another vane. Mincing chamber bottom accommodates grid and branch pipe to discharge finished product while chamber top is provided with vapor discharge branch pipe. Central part of each wavy vane has oval opening.
