Saving both water and energy
“Thanks to its automatic interior cleaning feature, our pasteuriser now no longer exhibits any biofouling, nor are there any unpleasant odours,” explains Sven Breitfeld. “Manual cleaning doesn’t take as long as it used to, we don’t have to factor in downtimes for boiling the machine out, and we can reduce our staffing levels. Usually, a pasteuriser is one of the principal energy-gobblers in a filling line. What’s more, we will be able to do entirely without chemicals.”
Besides the CLEAR system, the Marathon Belt was yet another important criterion for DIS, exerting a lasting effect on production efficacy. Marco Vossen explains: “The elongations customarily encountered with conveyor belts and created over years are substantially smaller with the Marathon Belt, because here stainless steel supports are used featuring plastic inserts. This increases the belt’s useful lifetime from five to approximately 20 years. Thanks to simple replacement of the plastic parts using the click-on principle, changing individual segments is also faster, without having to interrupt production for too long.”
Line utilisation markedly improved
The double-deck LinaFlex Pro pasteuriser was successfully acceptance-tested with an efficiency of over 98 per cent. The “Flying Product Changeover” automation system, plus two sweeper swivel arms, were also retrofitted; these automatically insert the last cans of a batch, and likewise automatically remove them at the end. This significantly upgrades operator safety, since it obviates the need for any manual intervention.
The system’s control functions have also been further upgraded: for the entire canning line, including the pasteuriser, a Krones LDS line documentation system has been ordered, whose tasks will include temperature monitoring as well. For this purpose, temperature loggers will be used in individual cans, enabling dependable pasteurisation to be evidenced.
“The trend towards cans continues unbroken, also and especially in Germany, despite the can deposit levied there. Manufacturers continue to report rising sales in this segment,” says Marco Vossen. Retrofitting the existing Krones canning line with the pasteuriser has substantially improved options for line utilisation. For Martin Gockel, Director Operations, one thing is for sure: “I’m very satisfied with the steps we’ve taken so far with this technology.”
