Mixing time bioreactor
WebIn bioreactors, mixing mainly depends on amount of energy consumed, reactor and stirrer shapes, airing speed and the rheology of the medium. In this work we experimentally determined the mixing times for a lab-scale bioreactor equipped with a stirrer propelled by two Rushton turbines. WebAbstract. The mixing time in bioreactors is discussed. Theoretical correlations for the mixing time in stirred tank and bubble column reactors respectively, are derived. …
