<p>In an aseptic packaging system, cartons L are indexed along an aseptic chamber M through which a main stream of aseptic air flows from a main inlet to a main outlet. At sterilizing stations, hydrogen peroxide is sprayed into the cartons L and the cartons L pass under UV germicidal lamps. Then, at a peroxide-removing station, a second stream of aseptic air is introduced, in a heated state and through a secondary inlet E, into the cartons L to vapourize residual peroxide and the second stream, carrying the peroxide, is drawn off through a secondary outlet N into a peroxide recovery circuit (G,K) leading, via a condenser I, a filter J, a fan A and a heater C, to the secondary inlet E.</p> |
