FIELD: food-processing industry; equipment for processing agricultural products by an extrusion. ^ SUBSTANCE: the invention is pertaining to equipment for processing agricultural products by an extrusion and may be used in the food-processing industry. The press-extruder contains a body of the main drive unit with a loading bin and a feeding mechanism, a composite feed screw and the cylindrical body of the feed screw consisting of detachable units. In the place of joint of the detachable components of the body of the feed screw there are the ring-type grooves used for the rigid fixation in them the rings with the internal slots directed at an angle to the axis of the ring. In the place of joint of components of the feed screw behind the ring rigidly fixed in the body, there is additionally a ring fixed on the shaft of the feed screw and having the exterior grooves directed at an angle to the shaft of the feed screw. The invention allows to reduce a backflow of the extruded material and to boost a degree of its comminution. ^ EFFECT: the invention allows to reduce a backflow of the extruded material and to boost a degree of its comminution. ^ 2 dwg |
