[目的]探讨益气通心胶囊成型工艺。[方法]使用吸湿率、休止角、堆密度、临界相对湿度等数据为考察指标,优选工艺条件。[结果]辅料(微晶纤维素、微粉硅胶)与浸膏粉配比为1:8为宜,生产车间及储存环境的相对湿度低于61%。[结论]为批量生产提供依据,内包装使用铝塑膜包装,贮存在阴凉干燥处,保证产品质量。 [Objective] To discuss the forming technology of Yiqi Tongxin capsule. [Method] Data of moisture absorption rate, angle of repose, bulk density and critical relative humidity were used as indexes to investigate the optimum process conditions. [Result] The ratio of auxiliaries (microcrystalline cellulose, silica gel) and extract powder was 1: 8. The relative humidity in the workshop and storage environment was lower than 61%. [Conclusion] To provide the basis for mass production, the inner packaging is packed in aluminum plastic film and stored in a cool dry place to ensure product quality.
