为提高水酶法提菜籽油的得率,对油菜籽进行挤压预处理,以提油率为考察指标,研究套筒温度、喂料量、螺杆转速、物料加水量对提油效果的影响。在单因素实验的基础上进行正交优化实验,确定挤压辅助水酶法提取菜籽油的最佳挤压参数。结果表明: 4个因素对提油率影响的大小顺序为:套筒温度>喂料量>物料加水量>螺杆转速;最佳挤压参数为套筒温度90 ℃、喂料量12 kg /h、螺杆转速210 r /min、物料加水量10%。经此挤压参数处理后的油菜籽,用水酶法提油时清油的提取率可达80.834%。

In order to improve the oil yield, extrusion pretreatment was employed for rapeseed before extracting oil by aqueous enzymatic method. The effects of barrel temperature, feed rate, screw speed and water addition were studied. Based on single factor experiments, the optimum extrusion parameters were determined by orthogonal test. The results indicatedthat the degrees of extrusion parameters on the oil yield were barrel temperature> feed rate>water addition>screw speed, the optimum extrusion parameters were as follows: barrel temperature of 90 ℃...
