СПОСОБ ВВОДА ВОДНЫХ СУСПЕНЗИЙ В КОРМА И ЭКСТРУДЕР ДЛЯ ЕГО ОСУЩЕСТВЛЕНИЯ

摘要

FIELD: equipment for utilization of high moisture content wastes of food-processing industry, which may be used in processing industries of agronomical and industrial complex. ^ SUBSTANCE: method involves extruding feed through die assembly equipped with at least one slit-type die; cooling extruded feed and drying in air flow which is fed so as to penetrate through layer of product; preliminarily separating suspension into dispersion phase and dispersion medium; introducing dispersion phase into feed before extrusion process and introducing dispersion medium during extrusion process. Extruder has cylindrical screw casing terminating in die, and screw with rod and at least one screw blade. Rod has internal cavity communicated with liquid supply channel and liquid discharge channel. Screw rod is provided with at least one opening for connecting said cavity with screw outer surface. Opening on screw rod surface is terminating with recess oriented transverse to screw axis and spaced from said opening in direction opposite to direction of rotation of screw. Liquid discharge channel may be equipped with overflow valve. Opening for connecting said cavity with screw rod outer surface may be provided in replaceable threaded plug. ^ EFFECT: increased efficiency in extruding of feeds with increased moisture content. ^ 4 cl, 3 dwg
