The impact of different baffles on liquid homogenization in crystallization process was described. In fermentation with crooked baffle, it was found that the flow field can provide more powerful driving force in the axial direction. And combined with the radial driving force provided by the disc turbine, dead zone at the bottom of blades was also eliminated. Due to its certain degree of twist, the flow field in the fermentation with crooked baffle can not only provide axial driving force, but broke the double circulation. Therefore the flow field in crystallization reactor eventually was distributed very well with dramatic reduce of adhesion.
