FIELD: agriculture. SUBSTANCE: method involves cleaning grain from contaminants; treating with propionic acid aerosol produced by atomization of propionic acid into gas flow during jet supplying of propionic acid onto end surface of rod-type longitudinal oscillation concentrator oscillated by means of ultrasonic source at frequency of 18-120 kHz. EFFECT: increased efficiency and prolonged storage life of grain.
