Innovative beer filling system: Dynafill

Beverage bottlers’ requirements are proverbially exacting: achieving progressively higher outputs while consuming less CO2 and nonetheless upgrading the filling quality – and all this in a sturdy system that’s ideally designed for cleaning. For beer filling, these are precisely the criteria Krones has satisfied with the new Dynafill.

And this product has some persuasively attractive pluses that compel respect: the machine halves the time required, saves distance, and replaces what used to be two machine units with a single one. How is this accomplished? The Dynafill performs filling and crowning in a single functional unit – and needs only five seconds for it. It can safely be claimed that the Dynafill concept is revolutionising beer bottling.

The most striking innovation involved is the actual filling process, which enables the bottle to be filled with beer within just 0.5 seconds. If you add in the crowning operation, then the entire process takes only 5 seconds. “The Dynafill offers major inherent advantages in terms of quality, since the system enables filling to be performed in a closed, defined atmosphere. The absence of a return gas during filling prevents the ring bowl from being pressurised with oxygen. Moreover, there is no fobber, and no open transport after filling. Since crowning takes place in a sealed chamber, the oxygen pick-up via the bottle’s head space can be minimised,” says Florian Habersetzer, Corporate Research and Development Process Technologies Krones AG, explaining the advantages of this new filling system.

The number of filling valves is reduced from 100 to 66, and this while retaining a rating of 36,000 containers per hour. The CO2 consumption is 20 per cent lower than with conventional systems.

The Dynafill can handle beverages in both coldfill and warmfill (temperatures of up to 30°C) modes – the process duration is, of course, in both cases less than five seconds. The filling process here always remains stable. Warm filling, too, now requires significantly fewer filling valves: 66 instead of 120 (likewise for 36,000 containers per hour).
