Krones Stromboli wort boiling system

The Stromboli wort boiling system is claimed to consume up to 40% less energy than its conventional counterparts.

In an internal audit, the system proved its resource-economy in operation, requiring less energy for boiling the wort. This is guaranteed by a standardised procedure certified by the TÜV SÜD technical inspectorate for awarding the enviro seal, in which all the system’s relevant consumption figures have been documented.

The award of the enviro seal was based on a whole series of features incorporated in the Stromboli system. One of the key technologies is the low total evaporation of 3 to 4%, plus energy feed precisely matched to the boiling phase. These permit energy savings of up to 4.5 kWh/hL of wort. At a total evaporation level of 4%, energy recovery systems can be deployed to optimum effect, less water is consumed during the wort production process, and savings can be made in terms of cleaning cycles and media. To make sure these show up in actual operation, Krones has expanded the operating and maintenance manuals to include recommendations for using the right processing materials and expendables to assure eco-friendly cleaning.

Optimum insulation of the vessel and the piping has enabled Krones to achieve lower heat losses. Further optimisation of the pump dimensioning has resulted in very low consumption figures.
