Wet corn milling facilities steep, grind, and process whole corn kernels using water-based separation to extract starch, corn oil, gluten feed, and sweeteners such as glucose, dextrose, and high-fructose corn syrup. Operations are typically continuous-process and capital-intensive, involving large centrifuges, evaporators, dryers, boilers, and pressure vessels. Output is sold in bulk to food manufacturers, industrial users, and sometimes pharmaceutical-grade buyers.
Questions to investigate
- What is the primary output — food-grade starch, industrial starch, sweeteners, corn oil, or a mix?
- What is the age and inspection status of boilers, pressure vessels, and major processing equipment?
- Has the operation experienced any product contamination events, recalls, or FDA/USDA regulatory actions?
- Are there any wastewater treatment or discharge permit obligations on site?
