Fermentation temperature control opitimisation in laboratory scale using MAX-MIN ant system and multi-point temperature instrument

摘要

Beer fermentation is a complex, non-linear process, to reduce the fermentation time while preserving fermentation quality parameters, following certain temperature control curve gains desired results. Dynamic optimization process of the beer batch fermentation is described. A temperature optimization profile is searched through ant colony system which is based on MAX-MIN ant system. A multi-point temperature inspect instrument was designed to obtain more temperature information in tank. The laboratory-scale fermentation set-up was built. The sensor helps to improve control precision. A smooth temperature profile was able to be obtained based on this optimization method, and it is easy to be presented as few linear segments.
