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 a mill is used in a variety of food products, such as bread, pastries, and pasta. The quality of flour can depend on the type of grain used and the milling process. Many mills also produce different types of flour, including whole wheat and gluten-free options.
