SMALL-SIZE PLANT FOR PREPARING FEED Russian patent published in 2015 - IPC A23N17/00 

FIELD: agriculture.

SUBSTANCE: device comprises a working chamber provided with a gear, and resiliently mounted on the base. The working chamber is made spiral-shaped with a repeated change in the flow cross section in shape and size throughout its length and with formation along its outer and inner perimeter of the multiple-thread screw surfaces and unidirectional multiple-thread helical lines. These surfaces provide the change in the direction of motion of the particle fluxes of the feed components and movement of the feed components from the loading to unloading. The working chamber is made of sections assembled from two subsections. The subsections are made of strips folded in one direction along straight fold lines, located at an angle to the edges of the strips, and folded to a ring with alternate formation along the length of the strip of different in size equilateral, isosceles and scalenous triangles. The sides of the triangles are different from each other by the same linear value that is a multiple to integer Δ.

EFFECT: use of the invention enables to expand the technological capabilities of the plant for mixing combined feed.
