Wheat Flour Milling Process

The cleaning part including mainly four steps: preliminary, cleaning, tempering, According to the trash content, we usually adopt three sifter, two scour, two stoner, one selector, three aspirator, three magnetic selectors, two adding water in order to reduce the trash content below 0.08%.
 

The general technological process of the cleaning part is: scalperator—gravity stoner – wheat storage bin- vibrator –magnetic selector- scourer- rotary sifter- gravity stoner- classificatory—auto dampener- tempering bin- blending machine-stoner- magnetic selector-scourer-rotary sifter-spraying water-flour mill.
 

And during this process, the auto tempering is very important for the product of the milling wheat, when the moisture is proper for the milling flour,, we can get the high flour rate, use the lower consumption, and also get the high quality flour. Before milling, the moisture of the milling flour should stay between 15.5%--16.5%, and 24 hours’ tempering is necessary, if it the soft wheat, the time can be a little shorter but regarding to the hard wheat, it should be longer. In the summer, the water can be inject a little bit less, and the time can also be reduce a while, but it is opposite for the winter.
