Improved dirt removal at Krones’ bottle washers

Tuesday 16 January 2007

Bottle washers rank among the most cost-intensive pieces of equipment in a line, which is why their availability, their resistance to malfunctions and their efficiency are vital considerations. In order to improve the efficacy of the dirt removal function, Krones AG, Neutraubling, Germany, has developed a new pre-soak concept.

Given a typical line size of 60,000 bottles an hour, about 1 g of dirt is brought in per bottle (excluding labels). That’s 60 kg an hour, which with a weekly constant running time of 150 hours adds up to 9 tons. Before starting development work, Krones asked itself the fundamental question: what’s the best way to cope with such a conglomeration of sand, beverage residues, crowns, cigarette ends, glass fragments and bits of dress.
