Wheat starch and gluten solution turnkey project

General process description:  

(1) Flour Conveying and Dough Preparation：From the bottom of the storage silos, the flour is extracted by vibrating extractor and dosing by rotary valve. Flour is fed into sifter for separating out the residues in the flour before the flour is brought into belt balance. After balance, the flour is mixed with appropriate proportion water by dough mixer. After mixing, the thickness of the slurry should be 12-15Be0 that is suitable for homogenizing in homogenizer. Then, the slurry is sent into tri-canter.

(2) Separating of Gluten& B-starch, A-starch and Pentosan: Tri-phase decanter divides the flour slurry into three portions according to the mixture’s specific gravity difference. Most of the fiber and A-starch is carried to the rotary screen. The starch contains A/B-starch and gluten are fed to 2 stages rotary screen. The light substance such as pentosan is carried to storage tank.
Left matter on the rotary screen (pure gluten) is re-circulated to 2stages rotary screen for increase the yield in gluten.

(3) Concentrating and drying of A-starch: The A-starch milk entering the 2 stages fiber centrifugal sieve is divided by two parts: A-starch milk and the left matter that contains much fiber. The wet fiber can be transferred directly to storage tank of pentosan.
A-Starch milk is transferred to the decanter through starch pump. The function of decanter is washing and refining starch. Pure A-starch will be sent to second decanter for concentration. Finally, A-starch is sending to peeler centrifuge and dryer to get final product.

(4) Refining of B-starch: after 2 stages rotary screen, the A/B-Starch milk is transferred to the decanter through starch pump. The function of decanter is separating A-starch & B-starch, and washing B-starch. Then the B-starch milk enter the centrifugal sieve and be divided by two parts: B-starch milk and the fiber.
Pure B-starch will be sent to second decanter for concentration. Finally, B-starch is sending to B-starch dryer to get final product.

(5) Water system：In this system, all fresh water and process water are sent to different places for cleaning, blending use, waste water treatment plant, etc. The suitable chemical should be applied in this section to get good result.  Also the safety water tank should be available in this section for machine use.

(6) Gluten drying: Wet gluten is sent to a gluten press for removing the moisture as much as possible. In the ring flow dryer, the vital gluten with moisture less than 9% is finally produced.
