Bean conditions, processing temperature and pressing time, solvent type and solvent-solid ratio were studied to optimize oil yield from castor beans. A maximum yield of 50.16% was obtained in this study. Moisture content of 3-3.6% was found compared to the range of 5-7% reported in literature. Isopropanol, hexane and their 50:50 by volume mixture were used as solvents for oil extraction. The optimum conditions were found to be isopropanol, temperature of 1080C, pressing time of 60 minutes and solvent to liquid ratio of 6:1.
