摘　　要：为改进油茶果脱壳机性能,提高脱净率、降低破籽率,基于油茶果的生物特性和常见脱壳机工作原理及结构特点,采用挤压、揉搓原理,提出一种螺旋挤压式脱壳间隙可调的高效低损脱壳方式,并通过EDEM构建油茶脱壳仿真模型,对脱壳过程进行可行性分析。选取脱壳辊筒转速、筛辊间隙、含水率3个因素,以脱净率和破籽率的综合加权评分为指标进行正交优化试验。研究结果表明:对综合指标影响的显著顺序为辊筒转速、含水率、筛辊间隙,优化后的辊筒转速350 r/min、筛辊间隙30 mm、含水率55%,此条件下进行8次验证试验,脱净率为97.19%,破籽率为2.85%,处理量可达到2 t/h。研究结果为油茶果脱壳加工提供参考。In order to improve the performance of camellia oleifera fruit husking machine,increase the removal rate and reduce the seed breaking rate,based on the biological characteristics of camellia oleifera fruit and the working principle and structural characteristics of common husking machines,a spiral extrusion method of camellia oleifera fruit husking with adjustable gap was proposed,and a simulation model of camellia oleifera fruit husking through EDEM was built.The feasibility of the dehulling process was analyzed.The dehulling roll speed,screen roll gap and water content were chosen,and the orthogonal optimization experiment was carried out with the comprehensive weighted score of the removal rate and the seed breaking rate.The results show that the significant order of influence on the comprehensive index is roller speed,water content and screen roll gap.The optimized roll speed is 350 r/min,screen roll gap is 30 mm,and water content is 55%.Under these conditions,three verification tests were carried out,and the removal rate is 97.19%,the seed breaking rate is 2.85%,and the processing capacity can reach 2 t/h.The research results can provide reference for the hulling processing of camellia oleifera fruit.
