Wheat starch processing equipment and gluten drying equipment process

Wheat starch processing equipment and gluten drying equipment processes include Martin method and three-step decanter method. Martin method is to separate gluten and starch through a washing machine, dehydrate and dry the starch slurry, and dry the wet gluten to obtain gluten powder. The three-step decanter method is to separate the starch slurry and wet gluten through a continuous washing machine, dry the wet gluten to obtain gluten powder, and separate the starch slurry into AB starch and protein separation through a three-step decanter, and then dehydrate and dry the starch slurry.

Martin method:
Washer separation: First, the wheat flour slurry is sent to the washing machine. In the washing machine, the wheat flour slurry is stirred and mixed, which causes the starch granules to separate from the gluten. Gluten is formed by protein in wheat, and starch is another major component.

Starch slurry dehydration and drying: Once the gluten and starch are separated, the starch slurry is sent to a dehydration device, usually a centrifuge. In the centrifuge, the starch granules are separated and the excess water is removed. The starch slurry is then fed to a drying unit, usually a starch airflow dryer, to remove any remaining moisture until the starch is in a dry powdered form.

Wet Gluten Drying: On the other hand, the separated gluten is fed to a drying unit, usually a gluten dryer, to remove moisture and produce gluten powder.

Three-stage Decanter Process:
Continuous Washer Separation: Similar to the Martin process, the wheat flour slurry is fed to a washer for processing. However, in this case, the washer may be a continuous process in which the wheat flour slurry is continuously flowing and mechanically agitated to more effectively separate the starch and gluten.

Wet Gluten Drying: The separated wet gluten is fed to a gluten drying unit to remove moisture and produce gluten powder.

Starch Slurry Separation: The starch slurry is fed to a three-stage decanter centrifuge. In this unit, the starch slurry is subjected to centrifugal force, which causes the starch particles to settle outward, while proteins and other impurities remain inside. In this way, the starch slurry is separated into two parts: Part A is a slurry containing starch, and Part B is a protein liquid separated from the protein in the starch slurry.

Starch slurry dehydration and drying: The starch slurry in Part A is sent to the dehydration equipment for treatment to remove excess water. Then, the starch slurry is sent to the drying equipment for drying until the starch becomes a dry powder.
