Method for preparing dendrobium officinale wall-broken slices

The invention provides a method for preparing dendrobium officinale wall-broken slices. The method comprises the following steps: selecting, washing/preparing, drying, crushing, grinding with a 100-mesh grinder, intermittently sterilizing, performing wall-breaking, granulating and drying to obtain the dendrobium officinale wall-broken slices. The prepared slices have good grain size and proper tightness; and the prepared granules can be easily dried and quickly dissolved, so that the slices can be easily dispersed when being taken by a user, can meet the requirement of microbial limit in terms of intermittent sterilization, and can be used for solving the problem that current commercial dendrobium officinale wall-broken slices are difficult to disperse and difficultly achieve the standard for microbial limit. 本发明提供种铁皮石斛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、间歇式杀菌、破壁、制粒、干燥制得铁皮石斛破壁饮片，制备的饮片的颗粒粒型较好，松紧度适中，而且制备的颗粒较易干燥，颗粒溶散较快，在使用者服用时易于分散，间歇式杀菌是的饮片满足微生物限度的要求，解决目前市场上铁皮石斛破壁饮片溶散难和微生物限度难达标的问题。
