Patent ID: 8389965

Claim:
An irradiation method, comprising: spreading logs; aligning the spread logs to be flush at one end; conveying the spread and flush logs laterally along a first conveying path; subsequently (a) passing the logs through a first throat plate arranged between an entrance to a second conveying path from the first conveying path and an arrangement of accelerators, and (b) conveying the logs longitudinally along the second conveying path and through an irradiation field formed by the accelerators, the accelerators being arranged centrosymmetrically about the second conveying path, electron beams of the accelerators subjecting the logs to a phytosanitary irradiation treatment; passing the logs through a second throat plate arranged between the arrangement of accelerators and an exit from the second conveying path; throwing the irradiated logs out in a lateral direction at the exit; and subsequently laterally conveying the logs away from a path of the longitudinal conveyance.
