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.
