Filtration and filling in beer production

Stabilisation of beer before bottling

The final production step before bottling of beer involves adding PVPP and/or Kieselguhr, to stabilise the beer and separate out solids and bacteria harmful to the beer, and then filtered. Kieselguhr, or diatomaceous earth is a naturally occurring, soft, silicon-containing sedimentary rock, which forms an additional filter layer on the filter candles and thus improves the filter process. The beer is filled into bottles, kegs or tanks at the filling machine. In order to preserve the carbonic acid in the beer, the filling takes place using a counter-pressure process, which at the same time prevents the absorption of oxygen and thus ensures the quality of the beer.

For these last process steps in beer production, KROHNE offers perfect solutions for level, pressure, temperature and pH measurement. Ultra-compact pressure transmitters for gap-free aseptic installation are suitable for very long-term stable tank level measurements. Modular differential pressure transmitters enable intelligent control of the wort filter. OPTIFLUX magnetic inductive flowmeters with high accuracy are suitable for these demanding hygienic applications. Additionally KROHNE is offering special flowmeters for bottle filling applications. BATCHFLUX 5500, the most precise and smallest device on the market for filling conductive liquids, is one example. Particularly fast, very precise hygienic temperature sensors are ideal for temperature monitoring. Finally sterilisable and completely autoclavable potentiometric pH sensors with integrated transmitters can reliably control the pH value at all stages of the process.
