The PET preforms are moulded in the line by a stretch blow-moulding machine into 20-litre containers, and fed to the filler via AirCo conveyors. The filler is a special machine from the Modulfill VFS series, with 18 specially modified large-size filling valves. As PET containers cannot be pre-evacuated, a blowing starwheel is inserted, through which the air in the containers is flushed out by means of carbon dioxide, thus preventing the filled beer from coming into contact with oxygen. This is already the third time that Krones has built this special filler for Carlsberg. Together with the upstream container rinser and the downstream six-head closer, it is accommodated in a cleanroom. In this case, the kegs are sealed with a pressure closure, which is pressed on, not screwed.
Plant Manager Martin Bjeld explains the reason why Carlsberg chose Krones kit for filling PET kegs: “Quite simply, Krones was the only vendor that was able to supply us with this technology comprising a short-tube filler for this high rating and with the filling parameters we wanted.” And Jeppe Holm-Jørgensen, who’s responsible for the kegging operation as Senior Line Manager, adds: “I’m very satisfied with the line. It operates with high-precision filling accuracy, fully automatically, and very reliably.”
Krones was the only vendor that was able to supply us with this technology for this high rating.
After being filled, the containers are transported in carriers suspended on belts. A Variocart carton erector feeds in the cartons, and after the beverage kegs have been date-coded and labelled, the Linapac II packer inserts four containers at a time in a carton. After a downstream weight check, a Variocol closes and seals the boxes, which are then labelled as well. Now a robot places 15 cartons at a time on a pallet, which is subsequently stabilised for transport with a net.
