General Process Flow
(1) Purifying: Elimination of foreign substances via rotary screen, de-stoning, and de-dusting.
(2) Steeping: Counter-current steeping at 50°C to soften the corn for crushing.
(3) Sulfurous acid making: SO2 gas generation and absorption to create steeping acid.
(4) Crash & Germ Separation: Two-stage milling and cyclone separation to isolate the germ.
(5) Fine Milling & Fiber Wash: Multi-stage washing for starch recovery and fiber drying for animal feed.
(6) Starch Washing: 12-stage hydro cyclones for final washing and foreign item removal.
(7) Starch Dewater & Drying: Peeler centrifuge dewatering and air flow drying to <14% moisture.
(8) Germ Oil Processing: Washing, dewatering, drying, and extraction for coarse oil production.
(9) Gluten Concentration: Air floating concentration and vacuum filter dewatering for gluten meal.
(10) Water Recovery: Evaporation of steeping liquid and recycling of process water.
