Grain Purchasing

Pioneer Flour Mills has very specific specifications that each grain must pass before we purchase any crop. A batch sample of each crop is sent to a state grain lab to ensure each crop meets our strict standards. Pioneer Flour Mills goes beyond the typical buyer seller relationship with each farmer. We work with each farmer to ensure a market for a superior product. In return, each farmer works with us to ensure a superior product for that market. The foundation of Pioneer Flour Mills, Inc. is a healthy, involved and committed relationship with our local Montana Agricultural community. Montana's farms are second to none and we're proud to mill and sell their products.

Grain Cleaning

Purchased grain is cleaned using a triple cleaning process before any milling occurs. Triple Cleaning Stages: 1. Air Screen - selects grains by width and length using screens. 2. Indent - selects grains by weight using circling indent tubes. 3. Gravity Table - selects grains by density. Extraneous Matter: All product is cleaned of wood, stones and other foreign matter. Every product is screened with a metal detector to eliminate any metal particles. Cleaning our grain allows us to ensure that our milled products, begin with a grain that will meet or exceed our customers expectations, no exceptions!

Cleaned grain is milled to yield a consistent, high quality flour. Using two state of the art machines after the milling process we can ensure a consistent, undamaged finished flour. Milled flour is first shot into a pneumatic receiver using negative air pressure. There are 65 tubular socks inside that swirling flour sticks to. Randomly, air is shot through individual socks knocking the collected flour loose. This process ensures weight consistency throughout the batch, not allowing the heavier flour to migrate away from the lighter flour. A very important process in yielding a consistent flour every time.

Milling Flour

Consistent flour is then moved through a state of the art Norvell sifter. This norvell sifter contains 16 different sifting boxes each controlled with electronically balanced counter weights. Each of these 16 sifting boxes separates the flour according to preset milling expectations. Flours can be sifted into a fine, medium or course grain, according to each end users needs. The sifted flour is then electronically weighed and packaged according to customer demands.
