A set of experiments has been performed in an industrial 112 m(3) fermentor in order to get a complete map of oxygen concentration and temperature distribution in the system. Five fermentations of non-Newtonian broths of two different strains, in various operating conditions, were examined. A simple model has been developed which takes into account both the mixing and the mass-transfer properties of the fermentor, and a dimensionless parameter has been identified which is sufficient to characterize the oxygen axial distribution in the reactor in any operating condition.
为了获得系统中氧浓度和温度分布的完整图谱,已在一个112立方米的工业发酵罐中进行了一系列实验。研究了在不同操作条件下两种不同菌株的非牛顿发酵液的五次发酵过程。已开发出一个简单模型,该模型同时考虑了发酵罐的混合和传质特性,并确定了一个无量纲参数,该参数足以表征反应器在任何操作条件下的氧轴向分布。
