Objective: To study on molding technology of Yanggan Yishui granule. Method: Category and ratio of accessories were investigated by taking moisture absorption percentage as index; Optimum molding technology were screened by taking moisture absorption percentage and molding rate of granule as indexes

and investigated angle of repose

moisture absorption percentage and critical relative humidity of granule. Result: Optimal ratio of soluble starch to β-Cyclodextrin was 2 ∶1

extract powder and adjuvants were mixed evenly in proportion of 1 ∶1

60% alcohol was added

dried at 60 ℃.Granules had a good fluidity

critical relative humidity was about 68%. Conclusion: This molding technology was reasonable

feasible and could provide scientific basis for production.
