The analysis of research on the separation of rice seeds on new types of polymeric sieves showed the absence of regularities that provide the studied processes. There are no dependencies describing the effect of the kinematic parameters of the operation of the sieves on the intensity of the separation processes of rice seeds. We performed a system analysis of the sieves with different types of holes. In the work, mathematical dependences between the amplitude and frequency of oscillations are determined for swinging polymer sieves.

The appearance of new types of polymer gratings on the market, which have other functional and technical-operational indicators, raises the question of new kinematic solutions to their work. In this paper, questions of parametric optimization of the functioning of this type of sieves from the angle of their origin and kinematic sieves are considered. We have carried out a system analysis of existing technological schemes of lattice mills and identified promising areas of modernization.

One of the main and most relevant and profitable areas of agricultural production - produce quality seeds in the farms, in the process of post-harvest grain processing. Was evaluated basic parameters of the separation process on the existing scheme sieve winnowing machine with certain technological characterization of the purified grain material according to the different conditions of separation, the possibility of defining a predetermined fraction of a feed and seed quality of purified material. Synthesis was performed variational various separation schemes and functioning to identify optimum operating parameters. According to the results of the experiment set technological possibility and the main characteristics of the process producing high-quality purified fraction of the material given by the scheme, which provides the best performance.
