In the current research, a centrifugal separator was developed for oil palm fruitlets to separate the mesocarp fibers from the nuts prior to oil extraction, which usually involves grinding the whole palm fruitlets to get the oil. This new technique can increase the yield of crude palm oil derived from the mesocarp without the presence of kernel oil from the nuts. This work focused on the effect of rotational speed and separation time on the mesocarp/nut recovery, oil yield, and broken nut percentage. It was found that the increase of rotational speed and milling time increased the mesocarp recovery without damaging the kernels. The oil extracted from the mesocarp was analyzed, and the results show that the oil properties such as free fatty acid, deterioration of bleachability index, and carotene were better than the properties of the palm oil extracted using the conventional method. From the optimization study, the maximum mesocarp recovery (60.84%) and palm oil extracted (46.02%) were obtained at 943 rpm of rotational speed and 20 s of milling time. The centrifugal technique allowed the separation of mesocarp from the nuts for a better palm oil extraction.

离心分离辅助中果皮纤维中棕榈油的提取和分离:中央复合设计的优化

在当前的研究中,开发了一种用于油棕小果的离心分离器,以在提取油之前从果仁中分离中果皮纤维,这通常涉及将整个棕榈小果磨碎以获得油。这项新技术可以提高中果皮衍生的粗棕榈油的产量,而坚果中没有仁油的存在。这项工作集中在转速和分离时间对中果皮/坚果回收率,产油量和坚果破损率的影响上。发现旋转速度和研磨时间的增加在不损害果仁的情况下提高了中果皮的回收率。对从中果皮中提取的油进行了分析,结果表明该油的性质如游离脂肪酸,可漂白性指数降低,胡萝卜素和胡萝卜素的性能优于常规方法提取的棕榈油。通过优化研究,在943 rpm的转速和20 s的研磨时间下获得了最大的中果皮回收率(60.84%)和提取的棕榈油(46.02%)。离心技术可使果皮与坚果分离,从而更好地提取棕榈油。
