China launched an important production of fuel-ethanol by fermentation of non-grain feedstock, with cassava mostly used as starch source. The industrial fermenters have diameters and liquid levels between 6 and 16m. The mixing of the fermentation broth is important for the efficient operation. Mixing is commonly achieved by the combined action of (i) an external recycle flow, and (ii) the gas-induced...
China launched an important production of fuel-ethanol by fermentation of non-grain feedstock, with cassava mostly used as starch source. The industrial fermenters have diameters and liquid levels between 6 and 16 m. The mixing of the fermentation broth is important for the efficient operation: this broth is a non-Newtonian suspension with viscosity around 0.3–0.7 Pa s, and a solids concentration...
