Objective： To investigate the optimization of the preparation process for Wuwei Anshen granules and to improve its quality. Methods： A single-factor experiment was performed to optimize the preparation process for granules. With the distribution of the diameter of dry granules after rolling granulation as the evaluation index,the influencing factors for dry granulation were evaluated,including rolling pressure,rolling rotation speed,and material transfer speed. Results： The optimized dry granulation process achieved a yield of intermediate g...
