| 摘 要： | 研究了油菜籽挤压膨化浸出制油预处理工艺。根据量纲分析理论和蒋亦元修正的G.Murphy定理进行试验设计和函数合成。选择菜籽粕的残油率为考核指标，以物料含水率、套筒温度、主轴转速、模孔直径、模孔长度、轴头间隙6个因素进行试验。通过试验建立了残油率与试验参数之间的经验公式，经检验该公式可对残油率较好地预测。

| Abstract: | The pretreatment technology of rapeseed extrusion for solvent extraction of oil was discussed. The experimental design based on the dimension analysis and G.Murphy theorem corrected by Jiang Yiyuan. The effects of extrusion parameters such as moisture content of material, temperature of barrel, rotational speed of screw, diameter and lenght of die nozzle, distance from screw end to die nozzle on the ratio of residual oil were studied . The experience formula was founded indicating the relationship between ratio of residual oil and extrusion parameters. The experiment indecates that the experience formula can predict the ratio of residual oil exactly. |
