Modeling and simulation of an oilseed meal desolventizing process

摘要

Most oilseed crushing industries use solvent extraction with commercial hexane to produce crude oils. Desolventization with steam in a desolventizer-toaster (DT) is used to remove the residual solvent from oilseed meals. In this study, a mathematical model is developed to simulate the desolventizing process and analyze the influence of operating variables in continuous equipment. Mass transfer phenomena are outlined to take into account different retention and transport mechanisms. Solvent diffusion Through pores from the solid to the vapor phase is analyzed and the contribution of axial dispersion along the bed is evaluated.
