Abstract

A bench-top machine would be suitable for farmers to separate palm mesocarp from palm kernels on a small scale. The purpose of this study was to conduct an experimental investigation on the efficiency of such a machine for palm mesocarp separation from the palm kernels with the following operational steps: (1) developing a separation machine having a pressing force measurement by upgrading an existing palm mesocarp separation machine; (2) conducting an experiment to determine a suitable operating point; and (3) examining the efficiency of the newly developed separation machine and analysing the extracted palm oil properties. The results show that suitable weight loadings for the cases without heating, with steaming, and with roasting are 1000, 1500 and 1500 g, respectively, whereas the optimal pressing distance is 19 cm. Deterioration Bleachability Index (DOBI) of palm oil extracted from oil palm mesocarp in the cases of no heating, steaming and roasting are 2.99, 3.68 and 4.15, respectively. In addition, the free fatty acid (FFA) in the cases of no heating, steaming and roasting are 3.89%, 3.14% and 2.72%, respectively. Therefore, DOBI and FFA levels satisfy the standard requirements for DOBI is not less than 2.00 and for FFA is not more than 5.00%.

棕榈中果皮分离机效率的实验研究

台式机器适用于农民小规模分离棕榈中果皮和棕榈仁。本研究的目的是通过以下操作步骤对这种从棕榈仁中分离棕榈中果皮的机器的效率进行实验研究：（1）通过升级现有的棕榈中果皮分离机器来开发具有压力测量的分离机器；（2）进行实验以确定合适的操作点；和（3）检查新开发的分离机的效率，并分析提取的棕榈油的性质。结果表明，在不加热、蒸和烤的条件下，最佳压榨距离为19cm，适宜的重量负荷分别为1000g、1500g和1500g。从油棕中果皮中提取的棕榈油在不加热，蒸和烤条件下的变质漂白指数分别为2.99、3.68和4.15。此外，在不加热、蒸和烤的情况下，游离脂肪酸（FFA）分别为3.89%、3.14%和2.72%。因此，DOBI和FFA水平满足标准要求，DOBI不低于2.00，FFA不超过5.00%。
