Preparation method of panax quinquefolius wall-broken decoction pieces

The invention provides a preparation method of panax quinquefolius wall-broken decoction pieces. Adopted medicinal materials are treated through the following steps: sorting and washing/preparing, drying, breaking, smashing through a smashing machine in 100-mesh sieve, intermittently sterilizing, breaking wall, pelletizing and drying, thus obtaining the panax quinquefolius wall-broken decoction pieces. The prepared decoction pieces are better in granule shapes and moderate in tightness; the prepared granules are easy to dry, dissolution and dispersion of the granules are faster, the granules are easy to disperse when a user takes the granules, the requirement on microbial limit can be met by the decoction pieces through intermittently sterilizing, and the problems that existing panax quinquefolius wall-broken decoction pieces in the market are difficult in dissolution and dispersion and are difficult to reach the standard of microbial limit are solved. 本发明提供种西洋参破壁饮片的制备方法，通过采用药材经过挑拣清洗/炮制、干燥、破碎、100目筛的粉碎机粉碎、间歇式杀
