Compact system for sterilization by bombardment of electrons

摘要

System for sterilization of objects (B) by electron bombardment comprising a chamber (2) provided with an inlet (4) and an outlet (6) through which objects (B) are input and output, said system between the inlet (4) and the outlet (6) comprising a treatment zone (II), a routing zone (I) upstream from the treatment zone (II) and an evacuation zone (III) downstream from the treatment zone (II), and means of conveying objects (B) from the inlet (4) to the outlet (6), the treatment zone (II) comprising at least one electron accelerator and a conveyor (9), the routing zone (I) and the evacuation zone (III) each including at least one radiation shielding wall (16) protecting against ionizing radiation and means allowing objects (B) to pass over the radiation shielding wall (16) passing over the top of said radiation shielding wall (16).

1. System for sterilization of objects by electron bombardment comprising a shielded chamber to confine ionising radiation provided with an inlet and an outlet through which objects are input and output respectively, said system between the inlet and the outlet comprising a treatment zone, a routing zone upstream from the treatment zone and an evacuation zone downstream from the treatment zone, the treatment zone comprising at least one electron accelerator and a conveyor, the routing zone and the evacuation zone each including at least one radiation shielding wall protecting against ionising radiation and conveyors, the routing zone and/or the evacuation zone comprising at least a first and a second conveyor on each side of the radiation shielding wall and a device for crossing said radiation shielding wall allowing objects to pass over the radiation shielding wall passing over the top of said radiation shielding wall, in which the crossing device comprises an arm mounted at a first longitudinal end on a shaft capable of rotating about an axis perpendicular to a displacement direction of the objects, said axis being contained in a plane located between the first and the second conveyor, a gripper for gripping the objects mounted on a second longitudinal end of the arm, means of rotating the arm such that it pivots between one end of the first conveyor and one end of the second conveyor and an actuator for actuating the gripper.
