Abstract
The article is devoted to improving the energy efficiency and quality of dry feed preparation in small and medium-sized farms. A three-factor experiment was used to examine the influence of the working tool speed (2.5-3.5 s-1), mixing time (120-240 s), and body tilt angle (25-35°) on the coefficient of variation and specific energy consumption. It was found that at a rotation speed of 3.5 s-1, a mixing time of 180-240 s, and a tilt angle of 30°, the coefficient of variation achieved is no more than 10%, which meets process requirements, while specific energy consumption is reduced to 12-15% compared to the baseline mode. The regression models obtained are reliable at a significance level of 0.95. The use of an active return channel ensures the formation of stable circulation flows and the elimination of stagnant zones.
