FIELD: agricultural engineering, in particular, equipment for preparing of mixed feeds in animal farms, complexes and poultry houses.
SUBSTANCE: extruding press has hollow casing with profiled inner surface and screw positioned for rotation within casing. Screw shaft is formed conical, with four-bladed knife fixed thereon. Knife divides casing into mixing zone wherein material is preliminarily compacted, and barometric treatment zone wherein material is exposed to barometric treatment procedure. Screw coiling in barometric treatment zone has reducing pitch. On discharge end of screw there is forming cone and grinding knife for grinding of end extrudate. Adjustable circular gap is formed between hollow casing and forming cone. Extrudate is to be discharged into said gap.
EFFECT: improved quality of mixed feed.
