Stone Mill Room

Stone milling is one of the latest additions to our facilities at NCI. In line with our mission, we've embraced the growing trend of producing nutritionally rich stone-milled and whole grain flours. We are equipped with a 26-inch granite stone mill with a 100-pound capacity grain hopper, along with a controlled grain feeder and flour sifter.

We have the capability to produce whole grain flours from a wide range of cereals and pulses, including modern and ancient wheat varieties, millets, pseudo-cereals, legumes, and beans. Our comprehensive work in whole grain milling also supports hands-on training, courses, and demonstrations at NCI. We can assist in developing stone milling processes for your grains to achieve the desired product. If you're part of our course, bring your grains or you can schedule an appointment, and together we'll explore stone milling approaches and operation for specific grains.

New American Stone Mill

The most recent of NCI’s milling additions is its New American Stone Mill. The stone mill is composed of a base and a runner stone. Both have grooves, or furrows, from the center of the stone to the edge of the stone. These furrows help to tear apart or open up the grain kernel, exposing the inner part of the grain to the flat portion, or the land, of the stone. The land portion is where the primary grinding of the grain into flour happens. The furrow also helps to move the product from the inner portion to the outer portion of the stone, as it is rotating on top of the bedstone. The stones are made of granite, so as the stone wears, pieces will not break off; rather, they will have a polished look, like sandpaper. Depending on the use and hardness of the grain, stones typically only need to be redressed once per year.
