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 wet cake, wherein the method comprises:
- (a) providing a wet cake comprising:
- a total solids content in a range from 15 to less than 35% (wt/wt) based on the total weight of the wet cake;
- (b) applying pressure to the wet cake to separate the wet cake into a liquid fraction and a solids fraction;
- and
- (c) recovering or separating oil from the liquid fraction.

A system for extracting oil from a wet cake, wherein the system comprises:
- a) a source of a wet cake comprising
- a total solids content in a range from 15 to less than 35% (wt/wt) based on the total weight of the wet cake;
- b) an oil liberation system in fluid communication with the source of the wet cake, wherein the oil liberation system is configured to apply pressure to the wet cake to separate the wet cake into a liquid fraction and a solid fraction;
- and
- (c) an oil recovery or separation system in fluid communication with the oil liberation 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 whole stillage or beer, wherein the method comprises:
- a) providing whole stillage or beer
- (b) separating the whole stillage or beer into a first liquid fraction and a first solids fraction, wherein the first solids fraction has a total solids content in a range from 15 to less than 35% (wt/wt) based on the total weight of the first solids fraction;
- (c) pressing the first solids fraction to separate the first solids fraction into a second liquid fraction and a second solids fraction and to move oil into the second liquid fraction;
- and
- (d) recovering or separating oil from the second liquid fraction.
