FIELD: extraction of fibrous material. SUBSTANCE: application of acoustic vibrations is effected with frequency of 18-20 kHz. In so doing, free end of concentrator of longitudinal vibrations of radiator is located in outlet of jet nozzle to form annual gap. End face of rod concentrator of radiator longitudinal vibrations and end face of jet nozzle are located in the same plane. EFFECT: higher efficiency. 2 cl, 2 dwg
