The results showed that process parameters varied with time in fermentation was distinct for different agitator and the hydrofoil impeller instead of the disc turbine impeller might significantly reduce power consumption under the same condition 研究结果表明：(1)与传统的涡轮搅拌桨相比，翼形轴流桨搅拌其发酵过程参数（粘度、溶氧、效价等）随时间的变化曲线有明显的差异；(2)在相同的生产条件下，用冀形轴流桨代替涡轮桨可有效提高生产效率。
