MACHINE FOR MAKING CONCENTRATED FEED Russian patent published in 2015 - IPC A23N17/00 

FIELD: agriculture.

SUBSTANCE: machine comprises a frame and a drum mounted on it with the ability of rotation, consisting of sections. The drum is made wave-shaped along the perimeter and is provided with four broken wave-shaped side surfaces and four broken wavy lines with a pitch variable in length of the drum, which increases as the flow cross section increases from the loading to unloading. The drum is made of sections mounted on the perimeter of the successively connected one equilateral trapezoid, two equal scalene trapezoids and a second, smaller in height than the first, equilateral trapezoid, the lower bases of which are equal to each other in each of the trapezoids and smaller than the upper bases which are also equal to each other in all four trapezoids, forming the square at the ends of the sections. The square of each subsequent section is rotated relative to the square of the previous one by the angle of 90°. Each attached section has the square sides of the lower base equal to the square sides of the upper base of the previous section.

EFFECT: use of the invention enables to improve the quality of prepared feed.
