Abstract

The infuence of particle size and solvent fow rate on the kinetics of oil extraction from soybean (eight fractions from 0.433 to 0.122 mm) was studied using hex�ane, simulating commercial percolation type extractor. The reduction in particle size from 0.433 mm to 0.141 mm showed an increase in the oil yield. However, further reduc�tion to 0.129 mm and 0.122 mm afected the yield due to bed compaction, reducing porosity and contact area. The yield (21.5%) of the ground mass was similar to the major mass fractions (0.239–0.353 mm). The rate of extraction increased drastically with the solvent fow rate. The highest fow rate (9.67 mL/min) exhibited the highest mass transfer coef�cient (km) 1.62× 10–3 s −1 and the difusion coefcient (De) 1.77× 10–12 m2 /s. At 7.33 mL/min, the yield and the rate of extraction were optimal and no potential benefts were obtained at higher fow rates.
