１９９７～１９９８ 年，研究了机械烘干对八角干果质量的影响和干果水分含量变化。结果表明：八角机械烘干的干果芳香油含量高，水分含量、碎口率与杀青晒干法差异不显著，成品质量达到市场商品要求，但其颜色需经过一定时间陈化后才转变为棕褐色。通过数理统计分析，建立了八角烘干水分变化的数学模型，并寻找出最佳烘干时间 From 1997 to 1998, the effect of mechanical drying on the quality of dried star anise and the change of dry fruit moisture content were studied. The results showed that the content of aromatic oil in dried fruit of star anise was high, the difference of moisture content, broken mouth rate and sun drying method was insignificant, the quality of finished product reached the requirement of market commodity, but the color had to be aged after a certain period of aging brown. Through the mathematical statistics analysis, established the octagonal drying moisture mathematical model, and find out the best drying time
