Abstract

A process for processing soybeans, said process comprising separating the soy sauce from a fermented mixture through decanting and splitting the soybeans into discernible pieces.

First claim

The invention claimed is:

1. A process for processing soybeans, the process comprising:
splitting the soybeans in a fermented mixture into pieces;
separating soy sauce from the fermented mixture through decanting, the separating of the soy sauce from the fermented mixture through decanting occurring after the splitting of the soybeans; and
the pieces resulting from the splitting of the soybeans being of a size by which the pieces do not form a powder.

2. The process of claim 1 , further comprising conveying the soy sauce through a clarifier.

3. The process of claim 1 , wherein the splitting of the soybeans is performed using a stator which includes a circular member possessing a circumference and plural holes arranged around the circumference.

4. The process of claim 3 , wherein the plural holes include holes possessing a rectangular cross-section.

5. The process of claim 3 , wherein the plural holes include holes possessing a circular cross-section.

6. The process of claim 3 , wherein the circular member possesses an inner diameter of 200 mm.

7. The process of claim 3 , wherein the circular member possesses a wall thickness between 4 mm and 6 mm.

8. The process of claim 3 , wherein the plural holes are sized to at least partially receive the soybeans.

9. The process of claim 3 , wherein at least some of the plural holes in the circular member are of different sizes relative to one another.

10. The process of claim 3 , wherein the circular member possesses a circular edge, and the plural holes are equidistant from the circular edge.

11. The process of claim 3 , including producing soy sauce having a protein yield of more than 2.5% per each produced liter of soy sauce.

12. The process of claim 3 , further comprising rotating the stator at a speed in the range of 1000 to 4000 revolutions per minute.

13. The process of claim 3 , further comprising rotating the stator at a speed in the range of 2000 to 3000 revolutions per minute.

14. The process of claim 1 , wherein the splitting of the soybeans includes chopping the soybeans into the pieces.

15. The process of claim 1 , further comprising adding brine to the fermented mixture before the decanting.

16. The process of claim 1 , further comprising conveying the soy sauce through a sieve and then conveying the soy sauce through a clarifier after conveying the soy sauce through the sieve.

17. The process of claim 1 , further comprising sieving the fermented mixture using a sieve after the decanting.

18. The process of claim 1 , further comprising controlling a temperature of the fermented mixture so that the fermented mixture is maintained at a temperature below 45 degrees Celsius.

19. A soybean processing method comprising:
slicing or chopping soybeans in a Moroni mixture using a revolving stator to split the soybeans in the Moroni mixture into smaller pieces and thereby increase a surface of the soybeans;
conveying the Moroni mixture through a decanter to extract the soybeans and soybean particles from husks and other impurities in the Moroni mixture, the conveying of the Moroni mixture through the decanter occurring after the slicing or chopping of the soybeans in the Moroni mixture.
