New aeration system enhances the efficiency of processing technology used for making baker's yeast.Peer-reviewed article

E. PÍŠ

In order to raise the productivity of fermentation installations used in plants making baker's yeast, i.e. to process more saccharide, secondary, nitrogenous and phosphorous components without increasing the dimension of installations, comprehensive research works were carried out in industry and specialized research institutes. The result is a new two-stage fermentation method hawing valuable advantages. One of the recent improvements of the process is a usage of a self-aerating system making of the whole processed match a homogenous, two-phase mixture with specific weight ranging from 0,3 to 0,65 kg/l. Such an aeration system introducing oxygen into fermenting mass can be realized in several ways. The article deals with the design and construction of an installation of the Vogel-busch system operating in the Trenčin yeast plant, with technology and with results achieved in fermenting small and large batches.
