Abstract

La présente invention concerne un système et un procédé pour désinfecter toutes les surfaces d'articles (101) transportés sur un système de transport (102) dans une chambre de désinfection (100) par irradiation ultraviolette (UV). La chambre de désinfection comprend un module désinfectant externe (104), un module désinfectant interne (107) et un module désinfectant mobile (108c). Le module désinfectant externe est une structure creuse cuboïde ou incurvée conçue pour se coupler mécaniquement avec une section d'un système de transport. Le module désinfectant interne est conçu pour désinfecter la surface inférieure de l'article sur le système de transport. Le module désinfectant mobile est conçu pour désinfecter des articles qui ne sont pas transportés en tant qu'entités individuelles sur un système de transport. La conception mécanique du système est telle que l'extérieur du système n'est pas exposé au rayonnement UV produit à l'intérieur de la chambre de désinfection.
