1. A method for recovering oil from a whole stillage byproduct comprising:
separating a whole stillage byproduct, via particle size, into a first insoluble solids portion, which includes fiber, and a first liquid portion, which includes free oil and protein;
thereafter, separating the first insoluble solids portion, via particle size, into a second liquid portion and a second insoluble solids portion, which includes the fiber, followed by dewatering the second insoluble solids portion, via weight, to produce a dewatered insoluble solids portion defining a wet cake, which includes the fiber;
combining the first and second liquid portions together to define a combined liquid portion, which includes the free oil and protein;
separating the combined liquid portion, via weight, into a lighter water soluble solids portion, which includes the free oil, and a heavier solids portion, which includes the protein; and
thereafter, separating the free oil from the water soluble solids portion, via weight, to provide an oil portion.
