Which is precisely why the people responsible at Spitz decided to upsize their filling capacities. Thanks to the fine performance of the existing wet-aseptic technology, they opted once again for Krones – but this time for dry-aseptics featuring a Contipure AseptBloc DN.
The new line began operation in August 2019, and is meanwhile running in three shifts. In each shift, one employee looks after the aseptic block, one supervises the labeller and the packer, and one is responsible for the palletising zone and supplying the line with new preforms.
Prior experience with Krones’ aseptics
Although Spitz was already familiar with Krones’ aseptic technology, in terms of process technology the new line differs from the existing wet-aseptic variant: the Contipure AseptBloc DN sterilises the preform’s entire surface in dry mode, using gaseous hydrogen peroxide. “This enables us to do without a rinser, which means we’ve been able to significantly reduce our water consumption and also the amount of wastewater created in the production operation,” says a gratified Markus Kröpfel, Technical Director at Spitz. Blow-moulder, filler and capper are in fully aseptic design and directly block-synchronised with each other. This guarantees not only a compact layout but also a high level of microbiological process safety.
