The design of a pneumatic threshing device for threshing ears of grain crops during selection work is proposed, which makes it possible to reduce grain injury. As a result of the experiments, it was found that crushing is completely absent during pneumatic threshing. At an air flow speed of more than 40 m/s, the efficiency of pneumatic threshing of ears is 100%, complete separation of all grains from the ears is ensured.
