Abstract
Systems and methods for extracting lipids of varying polarities from oleaginous material.
Claims19
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.
