Abstract: A plant to continuously decontaminate containers, comprising: a decontamination chamber having a tray having through openings and a feeding grid to feed at least one row of containers, which are aligned according to a first direction, along the tray, in a second direction, which is transverse to the first direction; a vaporized hydrogen peroxide generator to generate a gaseous mixture comprising air and vaporized hydrogen peroxide; a forced ventilation system to generate, in the chamber, a first flow of gaseous mixture that hits the row of containers from above; and a dispenser system arranged under the tray to generate a second flow of gaseous mixture, which hits the row of containers from below, through the through openings. The feeding grid comprises pushing members uniformly equidistant to each other along the second direction so that any pair of pushing members adjacent to each other can accommodate a row of containers.
