Abstract

The invention is relates to improved stirred-tank reactors which are suitable, due to special fittings, for converting the results of e.g. microbial or enzymatic processes obtained when they are used on a laboratory scale into an industrial scale. A shaft-driven disk agitator is provided, with at least one perforated disk being attached in the reactor above and/or below the disk agitator.
