Gravity separators are machines used to separate grains and dust by using the difference in weight between grains and dust. They work by causing grains to fall at different speeds, with heavier grains falling faster and lighter dust falling slower. The new gravity separator design is more efficient and effective than previous designs, making it easier to clean and maintain. It has the potential to revolutionize the separation process, saving businesses time and money. The new gravity separator is more effective at separating grains from dust and other impurities, improving the quality of food products and mined minerals. Additionally, it is also reducing waste.

The relevance of this study is conditioned upon the need to increase the amount of high-quality seed material of small-seeded crops, which cannot be achieved without an important process of separation. The separation is based on technical and technological principles of separation of seed material, depending on the differences in physical and mechanical properties of individual components of seed material. Cylindrical triers are used to separate seeds according to their length. The purpose of the study was to find the theoretical regularities of changes in the technological parameters of separation of the seed material of small-seeded crops from the structural and mode parameters of a cylindrical seed trier by numerical modelling. The solution of the set problems was implemented in the STAR-CCM+ programme based on the finite element method. Considering the physical and mechanical properties of the seed material, as a result of the study, a visualisation of the separation process was obtained depending on the research factors: the rotation frequency of the trier cylinder, the diameter of the cylinder, and the number of seeds and impurities in the seed mixture. According to the simulation results, the dependence of the relative content of impurities ε on factors under study was obtained in the form of second-order regression equations. Using the Mathematica programme, a compromise problem was solved, which lies in minimising the multiplicative function of the research criteria, and the rational constructive and technological parameters of the trier separator were found. The material of this paper is intended for scientists, graduate students, designers of agricultural machinery, students, and specialists in agricultural production.

Separation is an important process of processing seed material of small-seeded crops. This process is based on technical and technological principles of separation of seed material depending on differences in physical and mechanical properties of individual components of seed material. The quality of seed directly depends on the quality of separation. Cylindrical triers are seed cleaning machines designed to separate seeds that differ in length. The working body of the trier is a cylinder with an inner honeycomb surface and a prefabricated hopper, which is mounted on the axial support of the cylinder. The principle of operation of the trier is based on the rotation of the cylinder, during which the cells get seeds of different geometric sizes. The aim of the study is to determine the theoretical patterns of change of technological parameters of the process of separation of seed material of small-seeded crops from the design and regime parameters of the cylindrical honeycomb trier by numerical simulation. A model of the process of separation of seeds of small-seeded crops on a cylindrical honeycomb trier in the Simcenter STAR-CCM+ software package has been developed. Based on the physical and mechanical properties of seed material on the example of mustard seeds, the initial and boundary conditions of the cylindrical honeycomb trier, the separation process is visualized depending on research factors (number of seeds and impurities in the seed mixture, trier cylinder and trier cylinder and diameter). The next stage of research is to determine the dependence of the values of the minimum and maximum angles of seed exit from the cell of the trier cylinder on the research factors.
