A flour mill is a facility that grinds grain, typically wheat, into flour. The process involves several steps, including cleaning the grain, milling it into flour, and then packaging the final product. Flour mills can vary in size, from small, local operations to large industrial plants. Flour produced in these mills is used in a variety of products, such as bread, pasta, and pastries. The quality of flour can depend on the type of grain used and the milling process, which can affect the texture and flavor of the final baked goods.
