SETT OCH ANORDNING FOR RENGORING AV ETT FYLLROR VID EN FORPACKNINGSMASKIN

摘要

For cleaning the outside as well as the inside of a filler pipe in packaging machines of the kind which form a packaging tube around the filler pipe it is suggested to use a cleaning container (8) in the form of a tubular body (9) and a detachable base (10). The tubular body (9) surrounds the lower end of the filler pipe (4) and has an inside diameter greater than the outside diameter of the packaging tube (3); it may be provided with spraying nozzles (11). The base (10) is provided with a controllable outlet (16, 17). Cleaning is effected by circulation of a cleaning liquid that may be delivered via the interior of the filler pipe (4) as well as via separate nozzles (11) directed towards the outside of the filler pipe (4). The delivery of cleaning liquid through the filler pipe (4) may be reduced when the level in the cleaning container (8) exceeds a predetermined limit.
