Abstract:
1. An electron beam sterilizer which sterilizes vessels being conveyed by irradiation with an electron beam, comprising vessel holder means including a pair of holders which carries two vessels in vertical alignment, transfer means on which a plurality of vessel holder means are mounted at an equal spacing and cyclically transferred, inversion means for inverting the vessel holder means by rotating it about an axis parallel to a direction in which the transfer means advances, and an electron beam irradiator capable of irradiating the electron beam across the upper and the lower end of the two vessels which are carried in vertical alignment by the vessel holder means, the arrangement being such that a transfer path of the transfer means extends from a vessel feed position to a vessel discharge position and includes an inversion interval where the inversion means inverts the vessel holder means and an upright transfer interval where the vessels in vertical alignment are transferred in an upright position, the electron beam irradiator having an electron beam irradiation position which is chosen to be within the upright transfer interval, the vessels which are fed through the vessel feed position being discharged at the vessel discharge position after passing through the electron beam irradiation position and the inversion interval twice.
