Аннотация: Grain damage during threshing of ears caused by mechanical damage due to impacts from threshing machinery is a problem. A pneumatic method of threshing ears and a device for threshing are proposed. The threshing is carried out at contact interaction of the ears moved by an air stream with undulating surface of a deck. The threshing is carried out at various values of airflow speed, after which the portion of damaged grains is determined. It was found that no breakage of grains is completely absent as a result of pneumatic threshing. Complete extraction of all grains from the ears is provided at airflow velocity of more than 40 m/s. The graphical dependence of the number of damaged grains on the airflow rate has a complex shape with local maxima and minima. The optimum range of airflow rate, providing minimal damage to the seed and its germ, is 42 … 44 m s−1. The method of pneumatic threshing and device for its implementation need to be improved, since even at optimum values of airflow rate the share of damaged grain reaches 18%, including grain with damaged germ of 9%. In these parameters it is inferior to modern threshing devices. But this disadvantage is caused not by the inferiority of the new method of threshing, but by the imperfection of the technical device implementing it. The pneumatic threshing method and the device for its implementation is promising, but requires improvement of the threshing unit.
