`
`ABSTRACT
`(57)
`In one aspect of the invention, a method recovers oil from a
`concentrated byproduct, such as evaporated thin stillage
`formed during a dry milling process used for producing etha-
`nol. The method includes forming a concentrate from the
`byproduct and recovering oil from the concentrate. The step
`of forming the concentrate may comprise evaporating the
`byproduct. Further, the step of separating the oil from the
`concentrate may comprise using a centrifuge and, in particu-
`lar, a disk stack centrifuge. Other aspects of the invention
`include related methods and subsystems for recovering oil
`from thin stillage.
