Abstract
Disclosed are methods and systems for recovering oil from processed plant materials and by-products formed during a milling process used for producing ethanol.
Claims20
A method of extracting oil from a processed plant material, wherein the method comprises:
- (a) providing a slurry comprising:
- i) processed plant material;
- and
- ii) an aqueous carrier, wherein the slurry comprises a total solids content in a range from 15 to less than 35% (wt/wt) based on the total weight of the slurry;
- (b) applying pressure to the slurry to move oil from the process plant material to the aqueous carrier;
- (c) separating the slurry into a liquid fraction and a solid fraction;
- and
- (c) recovering or separating oil from the liquid fraction.

A system for extracting oil from a processed plant material, wherein the system comprises:
- a) a source of a slurry comprising:
- i) processed plant material;
- and
- ii) an aqueous carrier, wherein the slurry comprises a total solids content in a range from 15 to less than 35% (wt/wt) based on the total weight of the slurry;
- b) an oil liberation system in fluid communication with the source of the slurry, wherein the oil liberation system is configured to (adapted to) apply pressure to the slurry to move oil from the processed plant material to the aqueous carrier;
- c) a solid liquid separation system configured to separate the slurry into a liquid fraction and a solid fraction;
- and
- d) an oil recovery or separation system in fluid communication with the solid liquid separation system to receive the liquid fraction, wherein the oil recovery or separation system is configured to recover or separate oil from the liquid fraction.

A method of extracting oil from a processed plant material, wherein the method comprises:
- (a) providing a slurry comprising:
- i) processed plant material;
- and
- ii) an aqueous carrier, wherein the slurry comprises a total solids content in a range from 15 to less than 35% (wt/wt) based on the total weight of the slurry, wherein providing the slurry comprises screening the processed plant material to separate the slurry into a first liquid fraction and a first solid fraction;
- and
- (b) pressing the first solid fraction to separate the first solid fraction into a second liquid fraction and a second solid fraction and to move oil into the second liquid fraction;
- and
- (c) recovering or separating oil from the second liquid fraction.
