Spread of the coronavirus
Krones assumes responsibility for its employees, customers and business partners. We have taken numerous measures to slow down the spread of the infection and continue to provide our customers with the best possible support.
Filtration is one of the key processes in brewery operations. In addition to a bright, shiny filtrate with optimum turbidity, technological requirements also include an improvement in the physical stability of the beer. The filtration achieves high microbiological safety for the filled product.
On top of this, there are also economical requirements: Users want a long filter service life, low operating costs and systems that are easy to operate. These requirements form the basis for Phoebus, the new concept for cross-flow filtration.
At a glance
Controlled transmembrane pressure depending on the position of the module in the filter unit
Flow reversal at the membrane modules using a double infeed
Targeted backflushing of individual membrane modules during filtration and cleaning
The values from the pilot system show that the Steinecker Phoebus membrane filtration system provides a high beer quality and filtration capacity.
The pilot test showed consistent beer clarification with a yeast cell amount of 0 in the filtrate, as well as a considerably low iron absorption compared to kieselguhr filtration.
The membrane characteristics and filtrate quality were analysed in the test performed by the Technical University of Berlin.
Benefits to you
Thanks to the series connection of the membrane modules, the cross-flow process requires less energy compared to parallel connections.
Controllable filtration modules
It is possible to individually control the transmembrane pressure for different areas in the filter unit. It is also possible to extend the filtration intervals through targeted backflushing sequences with filtrate.
Hygienic plant operation
The ability to provide targeted, intensive flushing during cleaning and to provide 85 °C sanitisation allow a high standard of hygiene to be achieved.
Specific membrane development
Our cooperation with a competent and independent partner during membrane development means that the Phoebus can offer optimum filtration results.
With complete process technology from the brewhouse right through to filtration, Krones delivers precise and fitting brewery concepts.
