Optimisation of Wort Boiling by Process Reformulation and Design

Abstract

The current article introduces two possible optimisation tools for wort boiling. The first improvement tool refers to a reformulation of the different boiling phases. By a clever variation of the ratio between pump around velocity (turn rate) and evaporation velocity (evaporation rate) the advantages of a flash evaporation are combined with those of a kettle boil which leads to an optimised calandria boil (internal/external boiler). A second optimisation tool even intensifies this combination with a mechanical improvement. Thus, an energy reduction in wort boiling can be achieved which has so far not been possible to that extent.
