A review of our experience of operating Krones PoseidonTM dynamic fermentation systems including a comparison with conventional fermentation and conditioning in cylindroconical vessels
Abstract
In 2019 Coopers Brewery commissioned the retrofitting of eight fermenters with Krones Poseidon dynamic fermentation alongside an identical set of eight cylindroconical vessels. In 2023 a set of four new larger fermentation vessels installed, also fitted with the Poseidon system. A comparative study of beer fermentation has been conducted using different yeasts and performance had been assessed in regard to:
• attenuation rate,
• yeast health and cropping,
• diacetyl production and reduction,
• management of cold break and turbidity,
• management of dry hopping,
• ester profile and flavour,
• CIP effectiveness
This is a review of our ongoing learnings in operating the Poseidon fermentation system over five years.
