Abstract

Abstract A process for separating wheat gluten from the other components of the whole wheat kernel includes the steps of tempering the wheat kernel in water, flaking the wheat kernel, hydrating and agitating the flakes to just saturate the flakes and to form a thick, dough-like mass and mechanically working the dough-like mass in the presence of water to wash the wheat kernel components from the gluten.

Claims Analysis

Total Claims: 8
Claim 1
Independent Claim 109 words
A PROCESS FOR SEPARATING WHEAT GLUTEN FROM THE NONGLUTEN COMPONENTS OF THE WHOLE WHEAT KERNEL COMPRISING THE STEPS OF: A. TEMPERING WHOLE WHEAT KERNELS IN WATER TO A MOISTURE CONTENT BY WEIGHT IN THE RANGE FROM 15 TO 22%; B. FLAKING THE WHOLE WHEAT KERNELS TO A FLARE THICKNESS IN THE RANGE FROM 0.0005 TO 0,025 INCHES; C. HYDRATING THE FLAKES IN A QUANTITY OF WATER FROM 65 TO 75% BY WEIGHT OF THE FLAKES AND AGITATING THE FLAKES AND WATER TO FORM A THICK, DOUGH-LIKRE MASS; AND D. MECHANICALLY WORKING THE DOUGH-LIKE MASS IN THE PRESENCE OF WATER TO WASH THE NON-GLUTEN WHEAT KERNEL COMPONENTS FROM THE GLUTEN.
Claim 2
Dependent Claim 109 words
A PROCESS FOR SEPARATING WHEAT GLUTEN FROM THE NONGLUTEN COMPONENTS OF THE WHOLE WHEAT KERNEL COMPRISING THE STEPS OF: A. TEMPERING WHOLE WHEAT KERNELS IN WATER TO A MOISTURE CONTENT BY WEIGHT IN THE RANGE FROM 15 TO 22%; B. FLAKING THE WHOLE WHEAT KERNELS TO A FLARE THICKNESS IN THE RANGE FROM 0.0005 TO 0,025 INCHES; C. HYDRATING THE FLAKES IN A QUANTITY OF WATER FROM 65 TO 75% BY WEIGHT OF THE FLAKES AND AGITATING THE FLAKES AND WATER TO FORM A THICK, DOUGH-LIKRE MASS; AND D. MECHANICALLY WORKING THE DOUGH-LIKE MASS IN THE PRESENCE OF WATER TO WASH THE NON-GLUTEN WHEAT KERNEL COMPONENTS FROM THE GLUTEN.
Claim 3
Dependent Claim 24 words
A process, as claimed in claim 1, wherein said wheat kernels are tempered to a moisture content of from 16 to 17% by weight.
Claim 4
Dependent Claim 19 words
A process, as claimed in claim 1, wherein said mechanical working is accomplished by rotary tumbling of said mass.
Claim 5
Dependent Claim 27 words
A process, as claimed in claim 1, wherein said non-gluten wheat kernel components are retained in the wash water and are separated from the gluten by filtration.
Claim 6
Dependent Claim 22 words
A process, as claimed in claim 1, including the additional step of drying the gluten after separation thereof from the non-gluten components.
Claim 7
Dependent Claim 156 words
A process for separating wheat gluten from the non-gluten components of the whole wheat kernel comprising the steps of a. tempering whole wheat kernels in water at a temperature from 70*-90* F. to a moisture content, by weight, in the range from 15 to 22%; b. flaking the whole wheat kernels to a flake thickness in the range from 0.0005 to 0.025 inches; c. hydrating the flakes sufficiently to just achieve saturation in a quantity of water ranging from 65 to 75% by weight of the flakes to be hydrated and agitating the flakes and water to hydrate the gluten and to form a thick, dough-like mass; and d. tumbling said mass over projections in a rotary drum having perforations therein while concurrently washing said mass with water at a temperature in the range 60*-90* F., whereby the hydrated gluten is retained in said drum and the non-gluten wheat kernel components are washed through the perforations.
Claim 8
Dependent Claim 156 words
A process for separating wheat gluten from the non-gluten components of the whole wheat kernel comprising the steps of a. tempering whole wheat kernels in water at a temperature from 70*-90* F. to a moisture content, by weight, in the range from 15 to 22%; b. flaking the whole wheat kernels to a flake thickness in the range from 0.0005 to 0.025 inches; c. hydrating the flakes sufficiently to just achieve saturation in a quantity of water ranging from 65 to 75% by weight of the flakes to be hydrated and agitating the flakes and water to hydrate the gluten and to form a thick, dough-like mass; and d. tumbling said mass over projections in a rotary drum having perforations therein while concurrently washing said mass with water at a temperature in the range 60*-90* F., whereby the hydrated gluten is retained in said drum and the non-gluten wheat kernel components are washed through the perforations.
