Extraction With Fractionation of Oil and Co-Products From Oleaginous Material

A system for extracting lipids from an oleaginous material, the system comprising:

• a first, second, and third inlet reservoir;
• a transport mechanism configured to move the oleaginous material and a water-soluble solvent from the first inlet reservoir to the second inlet reservoir, and from the second inlet reservoir to the third inlet reservoir;
• a first separation device between the first and second inlet reservoirs, wherein the first separation device is configured to separate the oleaginous material and the water-soluble solvent into a first retentate portion and a first diffusate portion;
• a second separation device between the second and third inlet reservoirs, wherein the second separation device is configured to separate the oleaginous material and the water-soluble solvent into a second retentate portion and a second diffusate portion;
• a first recycle pump configured to pump the first diffusate portion to the first inlet reservoir;
• and
• a second recycle pump configured to pump the second diffusate portion to the second inlet reservoir.
