Energy consumption in fermentation processes

Abstract

The purpose of the present publication is to limit energy used to aerate the anaerobic fermentation processes. In yeast production the aeration process consumes the greatest part of the total energy required. A mathematical model, based on literature data, is presented for a yeast fermenter. the effect of various aeration and raw product strategies can be calculated. Simulation of yeast fermentation proves it to be independent of oxygen transport. However interaction between flow conditions and biological kinetics (glucose effect) is a limiting factor. With many feeding point the use of enegy for aeration (mixing) can be reduced to 1/3 of the present one.
