Continuous processes are known to have numerous potential advantages
compared to batch modes. Still, the technology has never succeeded on a
broader scale for main beer fermentation, mainly due to quality
deviations. Based on the knowledge gained from previous studies, an
alternative plant and process concept, therefore, was developed in order
to efficiently produce a stable, high-quality beer in a continuously
operated production plant. The concept foresees the use of classical
cylindroconical tanks, which are modified by the installation of central
pipes, so that two separate, yet interconnected, reaction spaces
result. Particles and organisms can sediment conventionally and may be
removed and recycled if required. The findings of numerous preliminary
experiments were used in order to construct a pilot-scale plant with a
daily production capacity of 50 L. With it, four long-term trials were
performed before the ideal parameters were determined to produce beer of
the targeted quality. Currently, a first industrial plant with 40,000
hL/annual capacity was commissioned based on the introduced principle.
In a cooperative research project the applicability of the developed
processes is being investigated.
Konrad Müller-Auffermann had already two years of international
experience, before he studied Brewing and Beverage Technology at the
Technical University of Munich (TUM). During his studies he worked for
several major construction companies, partly in foreign countries. In
2009, Konrad was employed by the Research Center Weihenstephan for
Brewing and Food Quality (TUM) as a consulting engineer specialized in
international brewing, fermentation, and filling technologies. One year
later he became head of the Research and Development and Hygienic Design
Department at the institute. The focus of his Ph.D. thesis was
continuous main fermentation methods and includes alternative plant and
process designs. In 2015 Konrad became head of Breweries Product
Development of KRONES AG.
