Abstract
Abstract A method for the separation of wheat gluten and wheat starch. A mixture containing wheat starch, wheat protein and water is treated in a hydrocyclone apparatus. The gluten agglomerates in the hydrocyclones and is carried along in the overflow fraction. The bulk of the starch is contained in a fraction separated at the tapping point.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
111 words
A method for the separation of wheat gluten and wheat starch comprising mixing water with a wheat product selected from the group consisting of wheat flour, whole wheat meal and flaked wheat, pumping the aqueous mixture into a hydrocyclone apparatus, agglomerating the wheat gluten of the wheat product while in the hydrocyclone apparatus, dividing the mixture by means of the hydrocyclone apparatus into an overflow fraction containing the agglomerated gluten and an underflow fraction containing the bulk of the starch, said agglomerating and said dividing being done in one single step within the hydrocyclone apparatus, separating the agglomerated gluten from the overflow fraction, and separating the starch from the underflow fraction.
Claim 2
Independent Claim
111 words
A method for the separation of wheat gluten and wheat starch comprising mixing water with a wheat product selected from the group consisting of wheat flour, whole wheat meal and flaked wheat, pumping the aqueous mixture into a hydrocyclone apparatus, agglomerating the wheat gluten of the wheat product while in the hydrocyclone apparatus, dividing the mixture by means of the hydrocyclone apparatus into an overflow fraction containing the agglomerated gluten and an underflow fraction containing the bulk of the starch, said agglomerating and said dividing being done in one single step within the hydrocyclone apparatus, separating the agglomerated gluten from the overflow fraction, and separating the starch from the underflow fraction.
Claim 3
Dependent Claim
41 words
A method according to claim 1 wherein the hydrocyclone apparatus into which the mixture is pumped includes a washing section, and fresh water is introduced into the washing section concurrently with the pumping of the aqueous mixture into the hydrocyclone apparatus.
Claim 4
Dependent Claim
37 words
A method according to claim 1 in which a portion of the liquid remainder of the overflow fraction after separation of the agglomerated gluten is used for the water in the mixing of water with wheat product.
Claim 5
Dependent Claim
21 words
A method according to claim 3 wherein starch is removed from the liquid remainder portion before mixing with the wheat product.
Claim 6
Dependent Claim
21 words
A method according to claim 1 wherein the temperature of the mixture in the hydrocyclone apparatus is raised above 30° C.
Claim 7
Dependent Claim
31 words
A method according to claim 5 wherein the temperature of the aqueous mixture in the hydrocyclone apparatus is raised to a range of 30° to 50° by introducing pre-heated fresh water.
Claim 8
Dependent Claim
22 words
The method according to claim 1 in which the hydrocyclone apparatus has a cylindrical part of 10 to 14 millimeters in diameter.
Claim 9
Dependent Claim
23 words
A method according to claim 1 in which there is a pressure drop of from 3 to 6 bars across the hydrocyclone apparatus.
Claim 10
Dependent Claim
23 words
A method according to claim 1 in which less than 3 cubic meters of fresh water per ton of wheat flour is used.
Claim 11
Dependent Claim
22 words
A method according to claim 1 wherein about 1.5 parts of water is mixed with one part of wheat flour by weight.
