Summary: Modern theoretical researches on the mechanical and technological processes for agricultural industry can be summarized by analytical methods, which lead to the compilation of complex systems of differential equations with boundary and initial conditions. These systems practically cannot be solved by traditional methods, so there is a necessity in their numerical solution via computer modeling. The molecular dynamics method and discrete element method, both of them based on the conception of a discrete structure of a substance, are the most interesting ones among all existing modern computer modeling methods for the mechanical and technological processes of agricultural industry. The purpose of these researches is to carry out the numerical modeling for some mechanical and technological processes for agricultural industry using the Star CCM+ computer software. There have been provided the results of the numerical modeling in the Star CCM+ computer software of the following mechanical and technological processes: mixing of components in a stream-type mixer-feeder, distribution of the straw underlay by the rotor spreader for the non-leash cow maintenance, formation of the pseudo-liquefied seed layer in the hydro-pneumatic seeding machine’s intake chamber, transferring of the oil crops seeding material with the air stream power, functioning of the photoelectric seed separators executing mechanism, technological process of the seed separation on an inclined vibrating surface. The given results point about the wide area of implementation of the numerical modeling for theoretical researches of mechanical and technological processes for agronomical manufacturing industry.
