Effect of air through-flow upon the oxygen transfer in fermantation plants.Peer-reviewed article

Z. AUNICKÝ, F. ŠTROS, R. ZÁBOJNÍK

The article deals with the results of experimental research works into the effects of air through works into the effects of air through-flow upon the oxygen transfer in fermentation plants. The authors have used for their experiments the models of fermenters of the 0,3 m³, 10 m³and 75 m³capacities. The research works cover both plants with pneumatic agitating systems. The intensity of oxygen dissolving was determined by using polarographic and sulphite methods. The authors discuss the effects of peripheral velocity of agitators, their diameter and air flow rate upon the oxygen transfer in plants with mechanical agitation.
