Abstract

Process and device for electron beam treatment of bulk material where the bulk material is fed into a continuous stream by means of compression stages (3) which can be evacuated. It is dispersed and directed into a dosed irradiation chamber (1), passing in this chamber through an irradiation field in a free-fall process, and discharged from the irradiation chamber through a compression stage system (4). The invention enables electron beam treatment of biological materials to be carried out to particularly good advantage, e.g. in combatting harmful organisms in seeds.
