目的 比较喷雾干燥法与减压干燥法时秦香止泻干浸青粉吸湿性及流动性的影响,为确定秦香止泻浓缩液(或稠浸膏)合理的干燥方法提供依据.方法 通过测定秦香止泻干浸膏粉的吸湿速度,吸湿量达2%时的相对湿度(relative humidit,RH),建立其动力学模型,提取吸湿速度参教并比较大小;通过测定秦香止泻干浸膏粉的休止角比较流动性优劣.结果 两种干燥方法制成的干浸青粉吸湿动力学模型皆符合对数正态分布模型,减压干燥比喷雾干燥吸湿速度快,吸湿量随RH变化的函数关系,喷雾干燥粉符合逻拜斯蒂模型;减压干燥粉符合修正指数函数曲线,吸湿量达2%时的RH,喷雾干燥粉为90.12%;减压干燥85.81%,减压干燥法比喷雾干燥法...

OBJECTIVE To select a reasonable dry method for extracting dry powdered Qinxiangzhixie, meanwhile to provide basis for future research, we compared the influence of spray drying and decompression drying on hydroscopicity and fluidity of dry powdered extract of Qinxiangzhixie. METHODS The moisture absorption speed of dry powder extract of Qinxiangzhixie was determined. Its dynamics model was established, when the relative humidity （RH） of moisture absorption reached 2%. The parameter of moisture absorption speed was collected and compared. Its...
