Abstract: Methods for pasteurizing and/or sterilizing particulate goods (1), containing the following steps: a) producing an electron beam (5), b) pasteurizing and/or sterilizing the goods (1) by the electron beam (5) in a treatment zone (3), wherein the electrons of the electron beam (5) have an energy that lies in the range of 80 keV to 300 keV, preferably from 140 keV to 280 keV, more preferably from 180 keV to 260 keV, the goods (1) being exposed to the electron beam (5) for a treatment time which lies in the range from 5 ms to 25 ms, and the electron beam (5) has a mean electron current density in the treatment zone (3) which lies in the range of 1015 s−1·cm2 to 2.77·1015 s−1·cm−2.

Abstract: Devices (10) and methods for pasteurizing and/or sterilizing particulate material. The devices contain at least one electron source (20) for generating an electron beam and a treatment zone (19) in which the material is pasteurized and/or sterilized by the electron beam. The device (10) comprises a vibration surface (11) which vibrates to convey and individualize the material. The first vibration surface (11) has a plurality of grooves (12) into which the material is conveyed and individualized. The device (10) has a material channel (21) in which the material is pasteurized and/or sterilized by the electron beam in the region of the treatment zone (19). The device (10) has at least one auxiliary channel (22) through which a fluid flows between the electron source (20) and the material channel (21) and is separated from the material channel (21). A cartridge (24) for pasteurizing and/or sterilizing particulate material is also disclosed.
