CONTINUOUS DRY MILLING METHOD OF WHOLE GRAIN COMPONENT EXTRACTION

摘要

Oil and protein are extracted from a plant-based feedstock using an extruder and a static mixer along with absolute ethanol and supercritical CO2. The overall process is a dry milling process which preserves the quality of the oil and the protein component of the plant-based feedstock.

1. A method for extraction of oil and protein from a plant based product the method comprising:
forming a feedstock from a plant based product having an oil component, a protein component, a starch component and a cellulose component, and a moisture content of to about 15.5 to about 16.5% by weight; subjecting the feedstock to pressure and shear to cause the feedstock to fractionate into an oil component, a protein component, a starch component and a cellulosic component; holding the fractionated feedstock in a vessel with agitation for a period of time to form a solid phase having the starch component and the cellulosic component, and a liquid phase having the oil component and the protein component; separating the solid phase from the liquid phase; separating the liquid phase into the oil component and protein component; collecting the oil component separate from the protein component; and collecting the protein component separate from the oil component.
