摘　　要：研究了油莎豆的物性参数并设计适用于油莎豆低温压榨制油的小型单螺杆榨油机,选取螺旋理论总压缩比、榨条间隙和出饼间隙3个因素,以饼残油率和油样含杂率为指标对榨油机结构参数进行正交试验优化。结果表明:自然晾晒后的油莎豆含水率约为6.71%,容重为0.7 kg/L,理论总压缩比对榨油指标的影响最为显著,优化后的榨油机理论总压缩比为10,5档榨条间隙依次为1.2、1.0、0.8、0.8、0.6 mm,出饼间隙为1.5 mm,在此参数条件下油莎豆低温压榨饼残油率为5.1%,油样含杂率为7.11%。该研究可为油莎豆低温螺旋压榨制油提供参考。The physical properties of Cyperus esculentus were studied,and a small single screw press was designed for low temperature pressing of Cyperus esculentus.The theoretical total compression ratio,gap between cage bar,gap between cakes were used as influence factors,the residual oil rate of cake and the impurity content of crude oil were used as indicators,and the orthogonal experiment was used to optimize the structural parameters of the press.The results showed that the moisture content and bulk density of the natural dried Cyperus esculentus were 6.71%and 0.7 kg/L.The theoretical total compression ratio had the most significant effect on the indicators,and the optimal structural parameters were obtained as follows:theoretical total compression ratio 10,and the gap between cage bar was 1.2,1.0,0.8,0.8,0.6 mm,and the gap between cakes 1.5 mm.Under these conditions,the residual oil rate of cake was5.1%,and the impurity content of crude oil was 7.11%.The study could provide a reference for the production of Cyperus esculentus oil by screw pressing.
