Hydrocyclone Method
Hydrocyclone process is another method of wheat starch and gluten production. Few companies in the wolrd prefer to use this method for their prodcution mainly due to high energy consumption.
Here is a brief review of HYDROCYCLONE PROCESS:
1-Mixing Flour and Water:
Flour and water mixed together in a certain ratio to form dough in dough making machine.After a certain time , dough goes to agitotator machine to form a slurry.
2- B-starch & Gluten & A-starch Separation
The slurry is pumped from agitator to hydrocyclone units.Gluten & B-starch are separated from A-starch and leave the hydrocyclone as light phase (overflow) to gravity sieves.A-starch leaves the hydrocyclone as heavy phase and goes to rotary sieve to separate fiber.
3- A-starch Refining and Concentration
After separation of fibers from A-starch, it goes to another hydrocyclone units for starch washing and concentration.
Concentrated A-starch then dewatered by means of Peeler or Vaccum Filter machine and is dried by an airflow dryer.
4-Gluten Washing and Drying
Gluten forms lump on grsvit sieves and goes to gluten washing machine .After washing and dewatering by means of screw press, it is dried by a gluten dryer.
5- B-starch Concentration and Dewatering
B-starch separated from gluten in gravity sieves , is concentrated by means of high speed disc separator. Concentrated B-starch leaves disc separator to centrifuge decanter for dewatering. Dewatered B-starch is dryed to commercial B-starch by means of airflow dryer.
