摘　　要：针对苜蓿为非均一性物质的特性,亟待提高各组分干燥程度的一致性。通过紫花苜蓿的生理和物理特性的试验分析,建立叶片、茎秆和草段的干燥特性曲线。利用基本的物理方法,确定最长干燥存留时间与苜蓿含水率的关系,机械处理次数和草段长度对苜蓿干燥速率的影响规律。试验研究表明：用机械压裂茎秆的方式处理的苜蓿与未处理的相比,干燥速度提高1.5-2倍。选择光滑槽压扁一次和纵向槽重复压扁三次处理的干燥效果最好。According to the characteristics of uniformity material on alfalfa,the drying consistency of alfalfa components would be improved. Drying characteristic curve of leaf,stem and grass were established by physiological and physical properties of alfalfa. Using the basic physical methods,the relationship of the longest drying time and moisture content of alfalfa was determined,and the effect law of mechanical processing times and grass length to alfalfa drying rate were studied. The experimental study showed the mechanical way of fracturing alfalfa was compared with untreated alfalfa,the drying rate was increased by 1.5-2 times. The best drying effect of squashed alfalfa stem was to use smooth slot one time and longitudinal slot three times.
