Abstract

This disclosure describes techniques for using a single feedstock of barley to produce a fermented product and a method for filtering a large-particles stream from a liquid stream containing small particles of a process stream using a series of mechanical separation devices to increase yield.

First claim

1 . (canceled)

2 . A method performed in a production facility, the method comprising:
receiving a first process stream, where the first process stream comprises milo as a first feedstock; filtering the first process stream to create a first large-particles stream from a first liquids stream containing small particles by using a first mechanical separation device; sending the first large-particles stream through a first shearing device to reduce particle sizes; sending the sheared first large-particles stream to a wet pad; receiving a second process stream, where the second process stream comprises corn as a second feedstock; filtering the second process stream to create a second large-particles stream from a second liquids stream containing small particles by using a second mechanical separation device; sending the second large-particles stream through a second shearing device to reduce particle sizes; sending the sheared second large-particles stream to a tank; adding a liquid to the sheared second large-particles stream to create a mixture in the tank; and sending the mixture to a dewatering device to create a third liquids stream and insolubles.

3 . The method of claim 2 , wherein the first mechanical separation device comprises at least one of a multi-zoned screening apparatus, a paddle screen, a filtration centrifuge, or a pressure screen.

4 . The method of claim 2 , wherein the first shearing device comprises at least one of a disc mill, an impact mill, a roller mill, a centrifugal pump, a ventri jet, or a hydroheater.

5 . The method of claim 2 , further comprising at least one of:
sending the sheared first large-particles stream to be mixed with wet cake to produce wet animal feed; sending the sheared first large-particles stream to be partially dried to produce partial-dried animal feed; or sending the sheared first large-particles stream to be dried to produce full-dried animal feed.

6 . The method of claim 2 , wherein the second mechanical separation device comprises at least one of a multi-zoned screening apparatus, a paddle screen, a filtration centrifuge, or a pressure screen.

7 . The method of claim 2 , wherein the second shearing device comprises at least one of a disc mill, an impact mill, a roller mill, a centrifugal pump, a ventri jet, or a hydroheater.

8 . The method of claim 2 , wherein the dewatering device comprises at least one of a screw press, a centrifuge, a rotary press, a rotary thickener, a filter belt, a wetter press, a belt press, a paddle screen, a vertical centrifuge, a washing centrifuge, or a medium pressure screen.

9 . The method of claim 2 , where the liquid comprises at least one of cook water, hot dilution water, or centrate.

10 . The method of claim 2 , further comprising at least one of:
sending the insolubles to be mixed with wet cake to produce wet animal feed; sending the insolubles to be partial-dried to produce partial-dried animal feed; or sending the insolubles to be dried to produce full-dried animal feed.

11 . A method in a production facility, the method comprising:
receiving a feedstock mixed with water to form a slurry in a tank; filtering the slurry as a process stream to create a large-particles stream and a liquids stream containing small particles by using a mechanical separation device; sending the large-particles stream through a shearing device to reduce particle sizes; mixing the sheared large-particles stream in another tank with a liquid to create a mixture; sending the mixture through a dewatering device to create another liquids stream and insolubles.

12 . The method of claim 11 , wherein the slurry comprises about 15% to about 44% solids.

13 . The method of claim 11 , wherein the process stream with the feedstock, comprises the feedstock is of at least one of corn, milo, barley, or sorghum grain.

14 . The method of claim 11 , further comprising sending the another liquids stream to be mixed in at least one of a slurry tank, a liquefaction tank, or a water makeup process.

15 . The method of claim 11 , further comprising at least one of:
sending the insolubles to be mixed with wet cake to produce wet animal feed; sending the insolubles to be partial-dried to produce partial-dried animal feed; or sending the insolubles to be dried to produce full-dried animal feed.

16 . The method of claim 11 , herein the insolubles comprise at least one or more of fiber, nonfermentables, germ, and grit.

17 . A pre-separation method in a production facility, the method comprising:
filtering a process stream to create a large-particles stream and a liquids stream containing small particles by using a mechanical separation device; sending a portion of the large-particles stream through a shearing device to reduce particle sizes; mixing the sheared large-particles stream in a tank with a liquid to create a mixture; and sending the mixture through a dewatering device to create another liquids stream and insolubles.

18 . The method of claim 17 , further comprising sending the another liquids stream to be mixed in at least one of a slurry tank, a liquefaction tank, or a water makeup process.

19 . The method of claim 17 , wherein the dewatering device removes moisture having up to 64% moisture.

20 . The method of claim 17 , wherein the mechanical separation device comprises at least one of a multi-zoned screening apparatus, a paddle screen, a filtration centrifuge, or a pressure screen.
