The starch mashing phase; the first one in the brewing process; has a fundamental influence on the quality of the final product. In particular; a good temperature control can significantly reduce the product variability; and also improve the process efficiency by (slightly) reducing the mashing phase duration. In this work; controloriented models o f the mashing process; including biochemical reactions’ representation and energy balance equations; are used to synthesise and test some temperature control schemes. The mix of equation- and algorithm-based modelling allowed by Modelica allows to size the control equipment to the (nearly) final detail; including for example the comparison of different types of heating actuators.
