Description

Technical Field

[0001] This utility model belongs to the field of whole wheat flour technology, specifically relating to a whole wheat flour milling device. Background Technology

[0002] Whole wheat flour refers to wheat flour that includes the outer bran layer, ensuring that the ratio of endosperm and bran is the same as that of the raw wheat. It is used to make whole wheat bread and cookies. Whole wheat flour is made from whole wheat grains through milling and sieving (grading to appropriate particle size), retaining the same proportion of endosperm, bran, and germ as the original whole wheat grain. Whole wheat flour is rich in nutrients and is a natural and healthy food. When you rub whole wheat flour in your palm, you can see crushed bran inside. It has a coarser texture than regular flour and a richer wheat flavor.

[0003] In the traditional whole wheat flour milling process, the filter screen is easily clogged by bran or coarse particles, requiring frequent machine shutdowns for manual cleaning, resulting in low production efficiency. Although existing vibrating screening devices can alleviate clogging, their complex structure and poor control over flour fineness, especially in high-fiber whole wheat processing, make the filter plates prone to jamming.
