Аннотація: The article investigates the dynamics of grain mixture movement on a plate spreader, taking into account the surface features of the working body and the influence of aerodynamic forces on the cleaning process. The boundary conditions are formulated and equations of particle motion are obtained, which allow us to estimate their trajectory and cleaning efficiency under the influence of air flow. The main factors that affect the uniformity of mixture distribution and quality of its cleaning, in particular the geometric parameters of the spreader, air flow rate, and physical and mechanical characteristics of the particles, are determined. Particular attention is paid to the role of vibration, which can be used to improve the processes of cleaning and pre-mixing the grain mixture before it is fed to spreader. Vibration contributes to uniform distribution of particles in size and density, which, in turn, can increase efficiency of subsequent cleaning by optimizing aerodynamic conditions. The possibility of integrating vibration oscillations into the grain distribution system to ensure flow stability and reduce the unevenness of its movement on surface of spreader is considered. The combination of aerodynamic and vibration effects can provide more efficient removal of impurities, improve the homogeneity of mixture and stabilize its movement during subsequent processing stages. The results obtained can be used to develop improved technological solutions in the field of post-harvest grain processing, in particular to increase the efficiency of cleaning grain mixtures. The proposed approaches are of practical importance for improving the design of equipment used in agricultural production.
