To satisfy the increasing worldwide demand for premium beers with an unaltered flavour profile, Bucher Unipektin AG Competence Center Filtration has developed Stefinox, a plant for cold sterile filtration of beer as well as wine, spirits, soft drinks and water.
The modularly designed plant consists of a pre-filter, a sterile filter, and a CIP filter connected upstream of these first two filters during the cleaning process. If required, Stefinox can be equipped with its own CIP station.
Designs for a continuous filtration process are possible. And it offers breweries economic benefits through potential energy and water savings as well as the free choice of suppliers for the filter cartridges.
Due to modern membrane technology, the gentle cold sterile filtration process makes thermal processes for microbiological stabilisation, like flash pasteurisation or tunnel pasteurisation, redundant. For a long time, the tunnel pasteuriser and later the flash pasteuriser used to be considered the first and only choice for the inactivation of yeast and beer-spoiling microorganisms in the bottling area. Stefinox changes everything.
