Wheat cleaning process:
Wheat - efficient vibrating screen+air separation - magnetic separation - wheat scourer+air separation - rotary sieve classifier+air separation - gravity stoner+air separation - magnetic separation – wheat washer – wheat tempering - wheat scourer +air separation - magnetic separation – clean wheat
Wheat milling process:
Clean wheat - fine crushing machine - screen - whole wheat flour - magnetic separation - metering packaging
It can be seen from the above process, whole wheat flour in the production of wheat cleaning process is basically identical with grade flour production, but the wheat flour milling process is different. Whole wheat flour milling process is very simple, while, grade flour milling process is complicated. It needs number of flour mill and screen for grinding and sieving.
In terms of economic efficiency, whole wheat flour has high nutritional value than the grade flour; in the terms of social benefits, whole wheat flour production make wheat bran from byproduct into food, improve the resource utilization of wheat, save food and easing the shortage of the human food resources.
In short, as people the improvement of understanding of whole grain food nutrition value, the development and production of whole wheat flour will continue, the improvement of dietary nutrition and health has great social significance and realistic significance.
