ABSTRACT:
In packing machines of the kind which form a tube of packing material for subsequent conversion into separate, filled packages, a filler pipe for the contents is usually arranged inside the material tube. Especially when the packing machine works with foodstuff under sterile conditions, the filler pipe as well as other machine parts situated inside the tube have to be carefully cleaned before and after production. As the filler pipe normally is surrounded by the foodstuff in the tube, it will have to be cleaned on the outside as well as the inside, and to facilitate the cleaning it is suggested to use a cleaning container, which has a controllable outlet and surrounds the lower end of the filler pipe and makes cleaning by circulation of a cleaning liquid possible. To increase the cleaning effect the cleaning liquid is circulated through the filler pipe as well as through separate nozzles directed towards the outside of the filler pipe.
