Patent ID: 8524929

Claim:
A method of extracting lipids from an oleaginous material, the method comprising: de-watering an oleaginous material; mixing the de-watered oleaginous material with a water-soluble solvent; heating the oleaginous material and the water-soluble solvent; providing a plurality of inlet reservoirs and a plurality of separation devices; directing the oleaginous material and the water-soluble solvent through the plurality of inlet reservoirs and the plurality of separation devices, wherein each of the plurality of separation devices separates the oleaginous material and the water-soluble solvent into a retentate portion and a diffusate portion; directing the retentate portion to a subsequent inlet reservoir and separation device; and recycling the diffusate portion to a prior inlet reservoir; wherein a first separation device separates the oleaginous material and the water-soluble solvent into a first retentate portion and a first diffusate portion; wherein a second separation device separates the oleaginous material and the water-soluble solvent into a second retentate portion and a second diffusate portion; wherein the first diffusate portion comprises a higher concentration of proteins than the second diffusate portion; and wherein the second diffusate portion comprises a higher concentration of lipids than the first diffusate portion.
