While products are mixed with solid and liquid by different density, it would be difficult to keep the mixture ratio in a desire rang, and cause the poor quality. Generally, the solid-liquid mixture of filling machines has equipped with stirred system. How to design the stirred system in a solid-liquid mixed filling machine to keep the radio uniformly is very important. For the design parameters of stirred equipment, the simulation software ANSYS FLUENT is used to analyze the change of mixture flow field. The bottom angle and diameter outlet of stirred tank, the location and speed of stirred blade are selected as parameters. Following the Taguchi method, liquid flow rate and particle volume / liquid flow rate of average value and standard deviation are analyzed. With the standard deviation to be as smaller as better, quality mixing equipment could be improved. The result of example shows that the average standard deviation of liquid system only is 7.4% reduced from the original, and for the particle volume / liquid flow model the average standard deviation is 78% reduced from the original. So, the improvement of parameters s the solid-liquid mixing radio be more uniform. The method proposes in this study also could be applied to any specified proportion of solid-liquid density.
