低温冷榨过程中油菜籽出油率影响因素仿真分析

Simulation study of factors influencing oil yield during cold pressing of rapeseed

目的:探究油菜籽在双螺旋榨油机中压榨时出油率的影响因素。方法:对油菜籽的压榨过程进行仿真,并探索榨螺转速和孔隙度两个因素对出油率的影响。结果:油菜籽出油率与孔隙度呈线性关系,孔隙度越大出油率越低;出油率与榨螺转速呈负相关。结论:当孔隙度为0.45,榨螺转速为20 r/min时,油菜籽出油率最高。

Objective:This study aimed to investigate the factors influencing the oil yield of rapeseed during pressing in a double screw oil press.Methods:To simulate the pressing process of rapeseed and to explore the effects of two factors,the speed of the press screw and the porosity,on the oil yield.Results:The oil yield of rapeseed was linearly related to the porosity,and a larger porosity,was associated with a lower oil yield.Moreover,the oil yield was negatively related to the speed of the press screw.Conclusion:The oil yield of rapeseed was highest when the porosity was 0.45 with the speed of pressing screw at 20 r/min.
