Kinetics of oil extraction from canola (rapeseed) - So - 1986

The extraction of oil from canola (rapeseed) using hexane as a solvent can be described by a two stage washing/diffusion model. Oil which is at the surface of the seed as a result of pressing or cooking is removed rapidly at the beginning of the extraction process by simple washing by the solvent.

The influence of extraction temperature and seed-to-solvent ratio in the ranges of 20–70 °C and 1:3–1:10 g/mL, respectively on the hempseed oil extraction by n-hexane was investigated in order to conduct both kinetic and thermodynamic analysis. For the kinetic modeling, it was assumed that washing and diffusion occurred simultaneously.
