“…1. Dependence of grain damage on the number of passes of the grain material [24] З рисунка 1 встановлено, що підвищення пошкодження зернового матеріалу збільшується залежно від кількості разів пропускання зернового матеріалу, а характер цієї зміни найбільш підпадає під експоненту залежність. Тому в першому наближенні отриману графічну залежність із рисунка 1 можна описати такою формулою: , (5) де -кількість разів пропускання зернового матеріалу через норію; -коефіцієнт, який враховує швидкість зростання пошкодження зерна; -коефіцієнт пошкодження зерна (%), визначається як:…”

Purpose. To determine the degree (magnitude) of grain damage at different stages of post-harvest grain processing and develop a rapid method for assessing grain damage using any technical means employed in the post-harvest grain processing line. Methods. The analytical research method is based on analyzing the degree of grain damage caused by technical means in the technological lines of post-harvest grain processing. Results. It has been established that the technical means used in technological lines result in different degrees of grain damage, and an analytical dependency has been obtained to determine the percentage of grain damage for each technological tool used in the technological chain of grain processing. Through experimental studies, a dependence of grain damage on the number of passes of grain material has been obtained, based on which an empirical relationship has been established in the first approximation, which expresses the dependence of grain material damage on the number of its passes. Conclusions. The proposed evaluation system allows for a quick assessment of the most significant damage caused by technical means in the grain cleaning line without excluding it from the technological process or disconnecting it from the power supply, taking into account the changing nature of the input grain damage. Keywords: grain damage, technological lines, cleaning of grain material, analytical method, noria, grain cleaning machine.

“…The quality of grain sorting is determined by the aerodynamic properties of the grain [9,[33][34][35] and the terminal velocity of the particles used in the pneumatic separation process [16]. Therefore, this experimental research aims to determine the influence of the vertical airflow velocity on the quantitative dispersion of grain mass parts, and grain flight of wheat grain.…”

In order to extend grain’s storage time and ensure its quality, it is necessary to sort and clean it. The aim of this study was to justify the rational shape of the sorting chamber and the optimal technological parameters for the sorting of wheat grains in airflow. This study used newly designed grain sorting chambers with constant, widening, and narrowing cross-sections for the airflow sorting of “Skagen” wheat grain. The aerodynamic properties of wheat grains were investigated when moisture was at 14 ± 2.0%. The grain flow rate in the chambers varied from 4 to 12 kg min−1 every 2 kg min−1. In addition, the airflow velocity varied from 8 to 12 m s−1 every 1 m s−1. The tilt angle of the constant cross-section camera was increased to 5°. Experimental studies have determined a terminal airflow velocity of 11.53 m s−1 for wheat grains. At the terminal airflow velocity, the grain flight coefficient was obtained to be about 0.074. These studies showed that the narrowing chamber is preferable for lower grain flow rates compared to the constant cross-section of the chamber. The widening chamber requires a lower airflow velocity to achieve the same performance and quality as the other chambers.
