The dissertation is devoted to the improvement of the technology of receiving and selling operations and storage of grain at grain terminals, which will improve the quality and efficiency of grain shiploads according to the requirements of contracts at grain
terminals. Recently, modern grain terminals have been built and are being built in Ukrainian ports for receiving, accumulating, forming export consignments of grain and shipping. However, little attention is paid to the issues of improving the technological processes of grain terminals. The regularities of grain delivery dynamics have also been insufficiently studied, there are no actual values of the duration of the individual stages of grain acceptance from various types of transport and the coefficients of uneven grain flow. There are certain problems with the formation of the optimal composition and ensuring the uniformity of grain
heavy shiploads. The dissertation presents the results of grain flow characteristics research by road in 2012-2018. The quantitative and qualitative characteristics of grain supplied by road and rail have been established. The ratio of the volumes of grain taken from vehicles and from the railway is shown. The features of the placement of grain masses in large metal silos are considered,
the uneven distribution of moisture and trash in the layers of grain during filling and unloading of silos is shown.
The dynamics of changes in the temperature of grain during storage in a silo, in which it was stored for a long period, has been investigated. The influence of various factors on the grain temperature was confirmed - the location of the silos relative to the
cardinal points, the proximity of the grain to the walls of the silos and the roof, the time of day, and others. It has been shown that the best time for measuring the temperature of grain in a silo is 7 or 20 hours, which give a weighted average grain temperature closer to the real one. The results of studies of grain masses flow dynamics by road and rail transport are presented. The periods of grain supply by road transport, daily average and maximum volumes of grain supply, as well as actual values of the coefficients of daily irregularity of grain supply by road transport have been determined. For grain terminals, the
concept of the coefficient of monthly irregularity of grain flow by road has been introduced. For 2018, this coefficient based on data from Ukrelevatorprom LLC was 1.73. Its use in the calculations of grain acceptance lines from vehicles will contribute to a
more accurate justification of the performance of the transport equipment of grain terminals.
The timing of nloading of cars was carried out, its longest stages were revealed and the ways of their reduction were shown.
Optimal composition of a ship export consignment of wheat grain weighing 35 thousand tons and its shipment at the grain terminal of LLC Ukrelevatorprom are presented. The article describes the results of the working patterns analysis of the movement
of grain and waste of grain terminals of LLC "Ukrelevatorprom" and LLC "Ilyichevsk Grain Terminal" The results of calculations and estimates of economic efficiency from the production of work results in the production process are presented. It is shown that the return on investment for the modernization (increase in productivity) of the grain shipping line for water transport will pay off by 20% in less than 3 years. Experimental verification of quality indicators of the export batch of wheat grain of the optimal composition in the volume of 40 thousand tons, which was formed at Ukrelevatorprom LLC. It confirmed compliance with the requirements of the contract for its quality, which provided a profit of 3312.3 thousand grivnas (UAH). The appendices show the chronological and deadweight characteristics of ships when delivering grain in 2013-2014, calculating the technical and economic indicators
of LLC Ukrelevatorprom when increasing the productivity of lines for delivering grain to water transport, recommendations for improving receiving and leaving operations and storage of grain at grain terminals, as well as acts of implementation of the results
of work in the educational process and production.
