Filling machine comprising airflow system8

Abstract

A paperboard container filling machine (10) comprising an aseptic chamber (30, 40), the aseptic chamber having: an upper air distribution chamber (35, 45); a lower processing chamber (36, 46) housing processing equipment (32, 42, 49) configured for interacting with paperboard containers passing through the processing chamber; a throughflow plate (37, 47) separating the air distribution chamber and the processing chamber; a paperboard container transport sub-system (12) configured for transporting the paperboard containers through the processing chamber along a container transport path (14) from an inlet opening (31, 41) to an outlet opening (33, 43) of the processing chamber; and an elongated air distribution duct (50, 53) configured for receiving air from an air supply channel and comprising a plurality of throughflow holes (51) configured for distributing the air in the air distribution chamber. The air distribution duct displays a semi-tubular convex surface (52) facing the throughflow plate and comprising a rectilinear duct axis (A) extending orthogonal or substantially orthogonal to the container transport path. A related method is also disclosed.
