Methodology of agitator design for large-volume bioreactors
Original language description
Substrates processed in biotechnological processes for the purpose of the production of biofuels are heterogenous suspensions with pseudoplastic flow behaviour. When these suspensions are mixed by high-speed impellers there is a risk that in more distant areas of the batch the shear stress is low and because of it the apparent viscosity is high and the fluid practically does not flow there. The fluid flows only near the impeller where the well agitated cavern is generated. Based on model experiments with real substrates for the production of second-generation biofuels the new methodology of designing the impellers process parameters for mixing in high volume reactors was proposed. This methodology includes recommendations for the choice of appropriate location of the impeller (centrally placed or side-entry impeller), the geometry of impeller blades and the determination of the number of impellers to ensure the circulation in the entire batch. For this geometric configuration of the mixing equipment the calculation method of estimation of the impeller speed needed for mixing in the entire batch and the calculation method of estimation of the impeller power input are described.
