The aim of this study was to evaluate the ventilation of grain crops stored in tower silos (750 tons of capacity, Vitkovice type). Medium-pressure fans (2 aerating fans for each tower) were used in order to provide 20 cube m of air per 1 ton of stored grain within 1 hour. The highest attention was paid to the principal parameter - the output air speed. The average air output speed from the stored grain layer along the tower perimeter is 0.101 m/s, the average air output speed in the tower centre, i.e. on the top of the pouring conus (1.8 m high), is 0.027 m/s. These values are sufficient to avoid grain deterioration.
