Decomposition of Technological Processes for Evaluating the Performance of Production Line for Pre Sowing Treatment of Seeds

An important step in improving the efficiency of crop production is the development of scientifically valid technologies and technical means of pre­sowing preparation and treatment of seeds. Among the various methods that have a positive impact on crop growth, early maturity and resistance to adverse conditions, one of the most promising is seed pelleting. (Research purpose) The reasonability of the use of pelleted seeds (dragees) was shown the shell composition of which includes the substances necessary for active growth and increase resistance to adverse effects, and, in addition, it provides a more accurate seeding. We substantiate the need for improvements to existing technologies and agricultural equipment (for example, seed pelleting machine). due to the significant lack of high­tech means of mechanization of seed pre­sowing preparation at domestic agricultural enterprises. (Materials and methods) Experimental studies have been carried out with the use of computer mathematical modeling. Results of experiments were processed by methods of mathematical statistics, statistical analysis and data processing package, research application package, filtering, analysis and modeling of technological processes. Physical and mechanical properties and quality indicators of seeds and fillers have been determined in accordance with the applicable state standards. (Results and discussion) Use has been made of a program that includes obtaining information about the processes to solve the problems of experimental studies carried out by machines for pre­-sowing treatment of seeds in accordance with the developed models of their functioning; the choice of the most effective means of measuring, recording and processing information about the operation of machines and equipment in normal operating conditions; as well as checking the effectiveness of the developed methods and tools to ensure the quality of the process in case of accidental disturbances. (Conclusions) The authors have studied main parameters and operating modes of a seed pelleting installation. An average values of the process parameters of the pre­sowing treatment of seeds have been calculated under the conditions of normal functioning of machinery and equipment taking into account the validity and reliability of the obtained characteristics. The authors have developed the technological fundamentals of the artificial coating of seed surface. The study results can be used as practical recommendations for the organization of pre­sowing treatment of seeds in order to increase seed germination and crop yields.
