This study analyses the results of research on the improvement of grain quality using a filling core in a grain silo. The research is a part of the research project aimed at developing an innovative system for drying and storing maize grain that, among other benefits, reduces grain damage. Two series were carried out: a control series, in which a chute was applied as the main element, and an operation series, in which a cascade chute was used for testing. The analysis conducted on the simulated operating conditions showed a 4-5-fold reduction in the amount of grain damaged following the application of the filling core compared with the control series. It has also been shown that a 6-meter cascade chute considerably decreases the velocity of the falling grain when loading the silo.
