Abstract
A flour milling method and a flour milling system are provided, in which a plurality of milling steps whose milling degrees are different from one another are performed sequentially from an upperstream to a downstream, each of the milling steps including a breaking step and a grading step. The steps are carried out by sorting the raw wheat grains into regular wheat grains and material other than the regular wheat grains, forwarding the sorted regular wheat grains to the uppermost-stream milling step, and forwarding the sorted material other than the regular wheat grains to at least one of downstream milling steps at a downstream of the uppermost-stream milling step. The method and the system enable the production of wheat flour of better quality with better yield than that conventionally produced.
