Increasing production and improving the quality of protein feeds, as one of the most important tasks in increasing the productivity of animals and poultry, can be achieved through the improvement of the meal processing technology, which is currently limited to grinding with subsequent incorporation into compound feeds. The advanced processing technology of meal developed at the Institute of Oil Crops, through the introduction of an additional mechanical fractionation operation of the ground meal into protein and husk fractions, allows for the extraction of more than 40 % of protein powder with a protein content of not less than 38 %. In addition to avoiding rapid oxidation, thanks to the granulation process, the storage volumes of pellets in warehouses will be reduced, and transportation costs will be minimized. Therefore, addressing the mechanization of meal processing through the improvement of technology and equipment for separating it into protein granules and husk fuel briquettes is quite relevant. The purpose – experimentally justify the constructive-technological parameters of the feed pelletizer. A screw installation design for manufacturing feed pellets from the protein fraction of oilseed meal has been developed as part of the technological line. The optimal design and technological parameters of the pellet manufacturing installation are a material feeding rate of q = 35.7 kg/h, a rotational speed of the working element of n = 50.5 rpm, and a moisture content of the protein fraction of W = 28.9%. In this case, the power of the installation is P = 973 W, and its productivity is Q = 48 kg/h.
