Traditional methods of palm oil extraction from palm fruits (Elaeis guineensis) produce low quality and quantity of oil. This study sought to design construct and test a motorised palm oil extractor with evaluation of the oil extracted in comparison with a manual vertical press. The performance parameters tested were oil extraction ratio (OER) oil extraction effciency (OEE) machine discharge effciency (MDE) and oil extraction losses (OEL) while the tested physio-chemical parameters were free fatty acids (FFA) iodine value (IV) saponifcation value (SV) and peroxide value (PV). There were signifcant differences (p0.05) in OER (16.20 and 13.53) OEE (77.13and 64.44) and OEL (18.30 and 24.76) while the MDE (81.70 and 73.13) were not signifcantly different (p0.05) for the motorised and vertical press respectively. No significant differences were observed for IV and SV while FFA showed significant differences (p0.05). The PV was not detected for both methods. A motorised palm oil extractor produced oil of higher quality and had higher performance efficiencies as compared to the manual vertical press. The novelty of this work was in producing an efficient equipment that is affordable to a smallholder farmer which extracts palm oil of high quality.

Abstract

Traditional methods of palm oil extraction from palm fruits (Elaeis guineensis) produce low quality and quantity of oil. This study sought to design construct and test a motorised palm oil extractor with evaluation of the oil extracted in comparison with a manual vertical press. The performance parameters tested were oil extraction ratio (OER) oil extraction effciency (OEE) machine discharge effciency (MDE) and oil extraction losses (OEL) while the tested physio-chemical parameters were free fatty acids (FFA) iodine value (IV) saponifcation value (SV) and peroxide value (PV). There were signifcant differences (p0.05) in OER (16.20 and 13.53) OEE (77.13and 64.44) and OEL (18.30 and 24.76) while the MDE (81.70 and 73.13) were not signifcantly different (p0.05) for the motorised and vertical press respectively. No significant differences were observed for IV and SV while FFA showed significant differences (p0.05). The PV was not detected for both methods. A motorised palm oil extractor produced oil of higher quality and had higher performance efficiencies as compared to the manual vertical press. The novelty of this work was in producing an efficient equipment that is affordable to a smallholder farmer which extracts palm oil of high quality.
