为探索油菜籽单位时间失水率影响因素,研究旋风式干燥方式下油菜籽的最佳干燥工艺参数,利用自制的旋风式油菜籽烘干机进行干燥试验。选取旋风式烘干机的干燥温度、气流速度、分级器内孔直径为主要因素进行单因素和多因素旋转正交试验。单因素试验发现旋风式烘干机的干燥温度、气流速度、分级器内孔直径3因素是影响油菜籽单位时间失水率的主要因素,其取值范围为:干燥温度70~90 ℃,气流速度17~22 m/s、分级器内孔直径130~140 mm;多因素试验表明,影响油菜籽单位时间失水率的因素显著性顺序为:干燥温度>气流速度>分级器内孔直径;旋风式干燥方式下油菜籽的最佳干燥工艺参数为干燥温度85 ℃、气流速度...

In order to explore the influencing factors of water loss rate per unit time during rapeseed drying, the optimum drying technolog ical parameters of rapeseed under whirlwind drying were studied. The drying experiments were also carried out by using the self-made whirlwind drying machine of rapeseed. The singleand multi factors rotating orthogonal tests were undertaken by choosing lhe main fac- tors including drying temperature, air velocity and the diameter of the inner diameter of the whirlwind dryer. The single factor test showed that the dry...
