VIBRATIONAL DEVICE FOR FEEDSTUFFS MIXING Russian patent published in 2012 - IPC A23N17/00 

FIELD: food industry.

SUBSTANCE: invention relates to devices for feedstuffs mixing. The vibrational device contains a framework and a drum installed so that to enable its rotation in the framework by means of a frame with pneumocylinders that is integrated into the device. The drum is made of sections mounted along the perimetre of the following alternatively connected trapezia: one equilateral trapezium and two equal non-equilateral trapezia and a second equilateral trapezium with a height less than that of the first one; the trapezia lower bases are equal to each other and less than the upper bases that are also equal to each other with all the four trapezia, the sections butt ends forming a square. The square of each subsequent section is turned relative to the square of the previous section through an angle of 180° or 90°. Each connected section has the lower base square sides equal to the previous section upper base square sides. A motionless screw header, designed in the form of an unidirectional hollow screw pipe, is mounted inside the drum at a distance L from the inlet hole of the drum. The header is made of three or more screw strips of equal width, convoluted in a vertical plane and sequentially connected to each other.

EFFECT: invention usage allows to enhance feedstuffs quality.
