Abstract
The control device according to the present invention includes an input device for entering measured data from a measurement unit, which measures nutrient components, the concentrations of oxygen, carbon dioxide, and biomass in a culture medium; a processor for calculating nutrient components uptake rate, oxygen uptake rate and carbon dioxide exhaust rate per unit amount of biomass from the measured data entered in the aforementioned input device, as well as volumetric mass transfer coefficient kLa from turbulent energy k and a turbulent energy dissipation rate e, both of which are calculated by a transport equation, as well as a diffusion coefficient D, followed by calculating the concentrations of the nutrient components, dissolved oxygen and dissolved carbon dioxide in any area in the fermenter; and a display for displaying concentration distribution of the nutrient components, dissolved oxygen, and dissolved carbon dioxide in the fermenter.
