Claim:
A method of increasing the yield of oil production in a process of producing bio-ethanol comprising: creating concentrated syrup as a by-product from an ethanol production, and recovering oil from the concentrated syrup, wherein the step of recovering oil from the concentrated syrup includes introducing the concentrated syrup to a horizontal axis centrifuge, using the horizontal axis centrifuge to recover oil, wherein the step of using the horizontal axis centrifuge comprises conducting the concentrated syrup into a bowl, separating the oil from the concentrated syrup using a screw and a baffle plate, wherein the step of using the screw and baffle plate includes discharging a recovered oil stream through a first outlet and discharging a deoiled syrup stream through a second outlet, wherein the step of using the baffle plate includes conveying deoiled syrup toward the second outlet and retaining oil at the baffle plate to prevent the oil from discharging at the second outlet.
