Claims24
A method of extracting oil from a biorefinery process stream, wherein the method comprises:
- diluting a biorefinery process stream to provide a diluted biorefinery process stream having a total solids content in a range from 15 to less than 35% (wt/wt) based on the total weight of the diluted biorefinery process stream, wherein the biorefinery process stream comprises at least grain oil, grain fiber, and water;
- and
- applying pressure to the diluted biorefinery process stream to separate the diluted biorefinery process stream into at least one liquid fraction and at least one solids fraction and to transfer oil into the at least one liquid fraction.
A method of extracting oil from a wet cake, wherein the method comprises:
- 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;
- and
- applying pressure to the wet cake to separate the wet cake into a liquid fraction and a solids fraction.
A method of extracting oil from a biorefinery process stream, wherein the method comprises:
- evaporating moisture from a biorefinery process stream to provide a condensed biorefinery process stream having a total solids content in a range from 15 to less than 35% (wt/wt) based on the total weight of the condensed biorefinery process stream, wherein the biorefinery process stream comprises at least grain oil, grain fiber, and water;
- and
- mechanically pressing the condensed biorefinery process stream against a screen to separate the condensed biorefinery process stream into at least one liquid fraction and at least one solids fraction and to transfer oil into the at least one liquid fraction.
A method of extracting oil from a biorefinery process stream, wherein the method comprises:
- providing a biorefinery process stream comprising a total solids content in a range from 15 to less than 35% (wt/wt) based on the total weight of the biorefinery process stream, wherein the biorefinery process stream comprises at least grain oil, grain protein, grain fiber, and an aqueous carrier;
- physically disrupting the biorefinery process stream, wherein physically disrupting comprises a process chosen from pressing, milling, and combinations thereof;
- and
- separating the biorefinery process stream into at least one liquid fraction comprising grain oil, and at least one solids fraction.
