Dry Granulating Technique Research of Zaorenshen’an Tablet by Orthogonal Experiment

摘要: 目的采用干法制粒工艺制备枣仁神安片，研究干法制粒的最佳工艺条件。方法采用L9(34)正交试验，以颗粒得率和颗粒脆碎度为评价指标，考察轧轮压力、轧轮转速、浸膏粉含水、物料传送速度的影响，优化干法制粒最佳工艺参数。结果最佳工艺参数为轧轮压力1.5 MPa，轧轮转速12 r·min^-1，物料传送速度50 r·min^-1，浸膏粉含水量不得超过6%。结论上述工艺稳定可靠，可应用于枣仁神安片的生产。

Abstract: OBJECTIVE To optimize conditions and parameters of Zaorenshen’an tablet, which was prepared by dry granulating technique. METHODS Taking granule yield and granule friability as measure indexes, the L9(34) orthogonal experiment was used to study the best conditions and parameters of dry granulating technique of Zaorenshen’an tablet. The factors, including roller pressure, roller speed, moisture content of power and transfer speed were studied in the experiment. RESULTS The optimal technique was: roller pressure at 1.5 MPa, roller speed at 12 r·min^-1, moisture content of power under 6%, transfer speed of mixture of drug and accessories at 50 r·min^-1. CONCLUSION The process of dry granulating technique of Zaorenshen’an tablet is stable and reliable, which can be used for industrial production.
