A Percolator for Defatting Oil Seeds by Solvent Extraction

Solvent extraction is a diffusion process wherein the solvent penetrates the oil-bearing cells of an oil-rich material; resulting in a solution of the oil-in-solvent (miscella). Major unit operations in solvent extraction include drying, cleaning, cracking/decortication, conditioning, and flaking of the seeds (Figure 1). When
