PRODUCTION METHOD FOR EXTRUDED COMPOUND FODDER WITH FORAGE HERBAGE ADDED AND EXTRUDER-CHOPPER

摘要

FIELD: food industry.;SUBSTANCE: invention refers to fodder production. Production method for extruded compound fodder with forage herbage added involves chopping of forage herbage to particle size of 2-10 mm, loading of grain components and chopped herbage into an extruder, their joint extruding, cooling and crushing of extrudate. Herewith the grain components and chopped herbage are loaded into the extruder separately. The forage herbage is chopped directly while loading to the extruder. The forage herbage is mixed with other compound fodder components after being extruded. The production method for extruded compound fodder with forage herbage added is implemented by an extruder-chopper comprising a chopper with a loading hopper, a screw feeder and an extruding unit. The chopper rotor is presented as a shaft with active circular cutters set perpendicular to its axis and having teeth on their outer edge, the chopper stator is presented as a fixed axle with passive circular cutters set perpendicular to its axis and having one-side sharpened cutting edge. Active circular cutters of the rotor and passive circular cutters of the stator are arranged in check order so that one active circular cutter is set between every two passive circular cutters.;EFFECT: invention implementation increases nutritional value of the produced compound fodder due to higher content of carotin and vegetable protein.;2 cl, 3 dwg
