The steeping process of a corn wet milling operation requires corn to be kept between 125 and 130 degrees for up to 40 hours. Because heat exchanger plates have such a large surface area, heat can be transferred evenly and accurately to large batches of corn over a long period of time.

at temperature around 75ᵒC during drying) are unsuitable for wet milling. The heat damaged corn affects the quality of oil extracted from its germ. Sufficient amount of moisture is added to the corn during steeping in the wet milling process in order to prepare the corn for subsequent degerming, grinding and separation operations.

Wet milling—as primarily a food production process—relies on a traditional food-production friendly solvent-based method of extracting corn oil, which usually relies on hexane. Hexane is extremely effective in this role (capturing 90 percent of the corn oil), and relatively easy to remove from the resulting extract, leaving pure corn oil behind.

The production of high fructose corn syrup (HFCS) by the process of corn wet milling requires large volumes of water for the steeping and milling operations. The water, incorporated into various process streams, creates extensive requirements for dewatering, drying, and evaporation, resulting in an energy-intensive process.

The Corn Refining Process or more than 150 years, corn refiners have been perfecting the process of separating corn into its component parts to create a myriad of value added products. The corn wet milling process separates corn into its four basic components: starch, germ, fiber, and protein. There are five basic steps to accomplish this process.

WET MILLING. In wet milling, the grain is soaked or "steeped" in water and dilute sulfurous acid for 24 to 48 hours. This steeping facilitates the separation of the grain into its many component parts. After steeping, the corn slurry is processed through a series of grinders to separate the corn germ. The corn oil from the germ is either ...
