LOOSE MATERIAL MIXER Russian patent published in 2012 - IPC A23N17/00 

FIELD: process engineering.

SUBSTANCE: invention relates to continuous-action drum mixers of fodder. Proposed device comprises foundation and driven drum. Said drum consists of sections made up of right triangular prism formed by cube diagonal cut. Like ribs of adjacent sections are connected at right angle. Said drum is arranged on frame supported by said foundation, its every section being turned relative to previous one through 90° and directed from loading side to unloading side with cross-section increasing in said direction. Every section consists of two subsections. First subsections is mounted on large right isosceles trapezoid with its lateral sides connected to 90° with larger lateral sides of two large scalene triangles with their bases equal to top base of said trapezoid. Second subjection is made up of small right isosceles trapezoid connected by lateral sides with smaller bases of two scalene triangles with their bases equal to small sides of large scalene triangles of the first subjection are connected therewith. Top bases of large and small right isosceles trapezoids are equal to each other and to bases if large scalene triangles of the first subsection are connected therewith to form small inlet of the section. Bottom bases of right isosceles trapezoids of two subsections are equal to each other and to larger lateral sides of small scalene triangles of the second subsection and connected with large lateral sides of small scalene triangles of the second subsections to make large outlet of the section. Discrete screw lines with pitch increasing along drum length from loading to unloading side.

EFFECT: higher quality of forage.
