We’d certainly consider our own milling system one day but for now happy with contract milling to ensure quality and correct flour specA group of farmers near here mill all their own wheat fir flour.the sell it to who ever wants and put it in the customers packaging. Very successful venture now but was slow to get going. Lots of regulations when the public are involved. They run the wheat thru rollers then seive it and go again until it’s finally ground up enough. Can’t be cheap but I’m sure china would sell you a small system reasonably priced
