Abstract. Seed sorting is a mechanical process in which the goal is to achieve a high level of purity and quality in the final product. Prediction and control of such processes are generally considered very difficult. One possible solution is a systems identification approach in which the seeds and their movement are directly observed and data about important process parameters extracted. Image analysis was used to extract such data from the internal sorting process in one particular seed sorting device -the so-called "indented cylinder". Twenty high speed image sequences were recorded of the indented cylinder in action, sorting a batch of barley with both whole and broken kernels. The motion trajectories and angle of escape for each seed in each frame were estimated. Motion trajectories and frequency distributions for the angle of escape are shown for different velocities and pocket sizes. A possible linear relationship is shown to exist between velocity and the angle. The temporal stability of certain parameters in the sorting process were also analysed and is shown to be quite stable for lower velocities.

The purpose of the research is to analyze the terrier separators of seed seeds of small-seeded crops and to develop an appropriate mechatronic control system, the use of which will perform the separation process with lower specific operating costs and higher productivity. The presented analysis of the technical support of the process of separation of seed material of small-seeded crops allows to assert the need to improve trier separators based on automated control of their parameters using photo or video recording of the process of separation of seed material with further processing. It is established that the definition of formal performance indicators of a cylindrical honeycomb trier is not trivial. The article develops a structural and technological scheme of a mechatronic system of a trier separator. The difference between the proposed system and the traditional one is that the camera fixes the trajectory of the seed flight. This information is processed in the control unit, which in turn changes the speed of the gear motor and, as a consequence, the drum with cells, the tilt angle of the tray, the angle of rotation of the damper with the stepping motor of the metering hopper. These manipulations with the operating parameters of the indented separator make it possible to adjust it to changes in the composition of the seed mixture, thereby increasing the quality of separation. In addition, due to the automatic adjustment of the operating parameters of the indented separator, the participation of the plant operator in the separation process is practically leveled, which reduces labor costs.

Nowadays, an important aspect for achieving a high level of seed production is the expansion of the range of high-quality seed material, which disrupts the technological process of separation and increases its costs. The purpose of the study is to analyse indented separator cylinders for cleaning small-seed crops and develop an appropriate mechatronic system for their control, the use of which would allow performing the technological process of separation with lower specific operating costs and higher productivity. The presented analysis of the technical support of the process of separation of seed material of small-seeded crops indicates the need to improve indented separator cylinders based on automated control of their parameters using photo or video recording of the seed separation with subsequent processing. It has been established that the determination of formal performance indicators of an indented separator cylinder is not trivial. Based on the results of the analysis, a design and technological scheme of the mechatronic system of an indented separator cylinder has been developed. The difference between the proposed system and the conventional one is that the camera captures the trajectory of seeds. This information is processed in the control unit, which in turn changes the speed of rotation of the gear motor and, as a result, the drum with cells, the angle of inclination of the tray, the angle of rotation of the flap with the stepper motor of the hopper dispenser. These manipulations with the operating parameters of the indented separator allow adjusting it to changes in the seed mixture composition, thereby improving the quality and productivity of separation. In addition, due to the automatic adjustment of the operating parameters of the indented separator, the participation of the operator in the separation process is practically not required, which reduces labour costs
