What Is

Dry Corn Milling

We love corn because corn is versatile. However, in its raw state, much of it is unusable to us. Corn is made up of starches (61%), corn oil (4%), protein (8%), and fiber (11%), with the remaining weight being composed of moisture. Through milling, we can break the corn down into new forms that are more digestible to both humans and animals. Various milling processes can be used to extract and use each of those components in different ways.

Dry Corn Milling Vs. Wet Corn Milling

 

There are two main processes for milling corn – dry corn milling and wet corn milling. Below, we’ll take you through the basics of both processes, and why we choose the dry corn milling process here at Fairview Mills, a division of J-Six Enterprises.

Dry Corn Milling Vs. Wet Corn Milling

In the wet corn milling process, corn kernels are soaked in large tanks filled with a sulfur dioxide solution. This softens the kernel, and the germ of the kernel is able to be removed. The germ is then processed separately to extract corn oil, and the resulting germ meal can be added to livestock feed. The kernels themselves are pressed through a series of screens. These screens separate the corn fiber from the corn starch and protein. The starch and protein go into a centrifuge to separate the two. The starches can be used in paper and textile industries, and as food sweeteners. The gluten protein is frequently made into a high protein meal used for animal feed.

Dry Corn Milling Vs. Wet Corn Milling

Dry corn milling was, for a long time, the only way to mill corn into other products. Instead of creating multiple different products, it produces a medium-to-fine grind meal. This meal, in turn, can be used as food products, animal feed, or fuel ethanol production. Hammers are used to crack, beat, and grind the dry corn kernels into a powder. As the meal travels from coarse to fine, a series of rollers and sifters take away unusable pieces. It’s as simple as that!

Our Milling Processs

At Fairview Mills

We process corn with a dry corn milling process here at Fairview Mills. Although the wet corn milling process can separate out each of the individual parts of the corn kernel, it is a much more costly process, produces a lower ethanol yield, and doesn’t create the type of fine grain meal that we’re looking for. The wet corn milling process also creates separate products with varying nutrition levels.

Using the dry corn milling process, Fairview Mills can create food-grade products that contain the full nutritional properties of corn. If the meal is intended for livestock or pets, the goal is the same – feeding your animals a corn meal that offers a wide nutritional range. We also want to help produce the ethanol that can ease the strain on our tenuous oil economy. The dry corn milling process helps us achieve these goals.

Fairview Mills sources our whole corn kernels from local grain elevators, or directly from local farmers within a 50 mile radius from our mill in Seneca, KS. Whereas other, bigger dry corn milling facilities might get their grain from all over the country or even overseas, we strive to shorten the supply chain and keep things centralized. We believe that supporting the local agricultural community will benefit everyone.
