摘要：
FIELD: agriculture.SUBSTANCE: device is described, including hoppers for loading raw materials, a raw material pre-treatment module, comprising screw elements with perforated surfaces, an extruder module, and a module for treating and drying granules. The raw material pre-treatment module has a cutting element for the stalk mass, made in the form of helical scissors, mounted of a rotating external helical perforated rotor with helical lower blades of one constant pitch and a rotating internal helical rotor with helical top blades of another constant pitch, arranged inside it. The external helical perforated rotor is equipped with helical lines and is made around the perimeter in the form of a multi-threaded helical perforated surface with helical grooves inside in the form of curvilinear pockets with the curvature centres of the curvilinear pockets, arranged inside its cross-section, and is made of three or more identical perforated strips of the rectangular form, twisted in the longitudinal direction with respect to the longitudinal axis and curved along the helical line in the transverse direction on a cylindrical mandrel, with forming on the perimeter of the external helical rotor three or more perforated internal curved surfaces of the convex shape with curvature centres within the external helical rotor and forming inside it overlaps in the form of helical lower blades of the helical scissors along the entire length from the inlet to the outlet. Along the entire length of the outer helical perforated rotor, an internal helical rotor is mounted, made around the perimeter in the form of a hollow cylindrical helical surface with external overlaps in the form of helical upper blades of the rotary helical scissors along the entire length of the helical surface made of three or more identical rectangular-shaped strips folded in the vertical plane in the longitudinal direction and curved along the helical lines in the transverse direction on a cylindrical mandrel and
