“…The oil content in the protein powder of 8-12% promotes its rapid oxidation, leading to a decrease in the quality of the protein additive. To increase the oxidation process time, it is proposed to produce the protein fraction in the form of granules [2,3].…”

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.

The same fractional composition and uniformity of distribution of raw material components of plant origin in the mixture are the main criteria for the liquid feed quality. This is ensured by the homogenisation and dispersion of feed components using cavitation treatment. The purpose of the study is to simulate the process of cavitation treatment of liquid feed with a rotary cavitation disperser-homogeniser and substantiate its rational design and technological parameters. The task is to create such a rotary cavitation disperser-homogeniser, which allows simultaneously performing technological processes of dispersion, emulsification, and homogenisation of mixture components in a liquid medium with higher productivity, quality, and lower energy consumption. As a result of modelling the action of a rotary cavitation disperser-homogeniser in the Star CCM+ software, the distributions and dynamics of velocities of the liquid phase of the mixture and the pressure and concentration of the gaseous phase of liquid in the diffuser are established, which indicates the presence of cavitation. This confirms the operability of the developed design and technological facilities for the preparation of liquid feed and indicates the expediency of further research to substantiate its technological parameters. As a result of numerical modelling of the operation process of a rotary cavitation disperser-homogeniser, the dependences of the maximum (max) and minimum (min) movement speed of the liquid phase of the mixture in the inlet Vin and in the diffuser Vrot on the rotor speed n, inlet diameter Din and the number of resonators Nhole are determined. The qualitative criterion for evaluating the cavitation phenomenon in the developed equipment is the maximum and minimum cavitation number Xmax and Xmin, which depends on the rotation speed of the rotor n, the inlet diameter Din and the number of resonators Nhole. The value of the cavitation number Xmin=0.08 and Xmax=0.57 is achieved at n=2725 rpm, Din=0.049 m, Nhole=48, which corresponds to a film flow of liquid with a stable separation of the cavitation cavity from the rest of the continuous flow (film cavitation)
