Abstract
Soft and moist vegetables are kneaded, severed and partially homogenized by a feed screw which rotates in a barrel and are admitted into a mincing unit wherein the partially homogenized material is severed by knives of a rotor which is surrounded by an apertured cylindrical stator. The comminuted material is thereupon caused to pass through the holes of an extruder and is severed behind the extruder to yield discrete crumbs which can be used as animal fodder or dried and ground to yield flour or farina, particularly flour or farina which can be used for the baking of tortillas. Vegetables which are admitted into the barrel are freshly harvested (such vegetables may include banana peels) or cooked. For example, dried grains of maize can be cooked in the presence of water and rinsed prior to admission into the barrel.
