Improving the Effectiveness of Isinglass Finings for Beer Clarification by Optimisation of the Mixing Process. Part 3: Full-Size Prototype Evaluation

Abstract

Previous work has identified the optimal two-stage static mixing process for a small-scale pilot rig. Protocols for scale-up to any brewery process line have been specified. A full-size prototype has been installed in a cask ale brewery. In most cases superior product clarity was obtained when the prototype was operated. Unexpected further benefits were demonstrated from mixing downstream of the mixing system and also disturbance and subsequent resettlement in the cask.
