Abstract

A process for making a high grade protein product, such as a mammalian feed product, using residue slurry from a cellulose fermentation and distillation process is provided. The residue slurry is compressed to remove much of the residual liquid. The compressed slurry is shaped, dried, leavened and granulated to provide the high grade protein product. Nutrients, flavorants, texturizers and other food product-enhancing ingredients may be added during the process. The granules of animal feed product can be packaged and stored in an inert or other stable environment for extended storage periods.

Claims

1. A process for making a high grade protein product from the residue of cellulose plant fermentation and distillation, comprising the steps of:

providing a residue that comprises a plurality of ingredients selected from the group consisting of distiller'"'"'s grains, dried distiller'"'"'s grains, residual alcohol, water, carbon dioxide, yeast, enzymes and combinations thereof;

compressing the residue to remove liquid ingredients and provide a compressed residue;

shaping the compressed residue to provide one or more strands;

drying the compressed residue; and

granulating the dried strands to provide granules of high grade protein product.

2. The process of claim 1, further comprising the step of leavening the one or more strands.

3. The process of claim 2, wherein the drying and leavening occur simultaneously.

4. The process of claim 1, further comprising the step of adding one or more product-enhancing ingredients selected from the group consisting of flavor enhancers, nutrients, texture modifiers and combinations thereof.

5. The process of claim 4, wherein the product-enhancing ingredients are added to the residue before or during the compressing step.

6. The process of claim 1, wherein the step of drying the residue is performed before the step of shaping the residue.

7. The process of claim 1, wherein the step of shaping the residue is performed before the step of drying the residue.

8. The process of claim 1, wherein the step of shaping the compressed residue is performed by extruding the compressed residue through an extrusion die.

9. The process of claim 1, wherein the high grade protein product has a moisture content of less than about 2% by weight.

10. A process for making a high grade protein product from the residue of cellulose plant fermentation and distillation, comprising the steps of:

providing a residue slurry that comprises a plurality of ingredients selected from the group consisting of distiller'"'"'s grains, dried distiller'"'"'s grains, residual alcohol, water, carbon dioxide, yeast, enzymes and combinations thereof;

continuously compressing the residue slurry to remove liquid ingredients and provide a compressed residue;

continuously shaping the compressed residue to provide one or more strands;

continuously drying the compressed residue; and

continuously granulating the strands to provide granules of high grade protein product.

11. The process of claim 10, further comprising the step of continuously leavening the strands.

12. The process of claim 10, further comprising the step of continuously adding one or more food product-enhancing ingredients selected from the group consisting of flavor enhancers, nutrients, texture modifiers and combinations thereof.

13. The process of claim 10, further comprising the step of adding inert gas to the granules to facilitate long-term storage.

14. The process of claim 10, wherein the residue slurry is continuously provided from a distillation process.

15. The process of claim 10, wherein the distiller'"'"'s grains and dried distiller'"'"'s grains are derived from cellulose plant feed selected from the group consisting of wood from trees, food plants, grasses, and combinations thereof.

16. The process of claim 10, wherein the high grade protein product has a moisture content of less than about 2% by weight.

17. A process for making high grade protein product from the residue of cellulose plant fermentation and distillation, comprising the steps of:

feeding a residue'"'"'slurry into an extruder, the residue slurry comprising a plurality of ingredients selected from the group consisting of distiller'"'"'s grains, dried distiller'"'"'s grains, residual alcohol, water, carbon dioxide, yeast, enzymes, and combinations thereof;

compressing the residue slurry in the extruder to remove liquid ingredients and provide a compressed residue;

shaping the compressed residue by extruding the compressed residue through an extrusion die;

drying the compressed residue; and

granulating the compressed residue to provide granules of high grade protein product.

18. The process of claim 17, wherein the drying is performed by exposing the strands to heated gas.

19. The process of claim 17, wherein the drying is performed by treating the compressed residue with compressed, heated gas followed by rapid decompression.

20. The process of claim 17, further comprising the step of adding one or more food product-enhancing ingredients to the extruder.
