Basically, when manufacturers use wheat flour mills to process wheat, they will find that the ash level of the finished product is different. The ash level of wheat flour is an important indicator to measure the purity of wheat flour. The higher the processing accuracy of the flour, the lower the ash content and the whiter the pink. So what is the reason for the different ash grades of finished products?
1. Wheat itself, the raw material for flour mechanical processing, is too gray;
2. In the whole flour mill, the wheat threshing machine has a great influence on the ash content of the noodle products, because it cleans not only the wheat hair of the wheat but more importantly, it removes all kinds of attachments in the groin of the wheat at the same time. Therefore, the operators of flour machinery should pay special attention to the sieve plate of the threshing machine. The degree of damage of the sieve plate has a great influence on the ash content of flour products;
3. Improper moisture regulation. We all know that the tempering time has a great influence on the power consumption per ton of flour, but it has a greater impact on the ash content. If it is dry, the flour extraction rate will increase, and the ash content of the flour will also increase. If it is wet, the flour extraction rate will decrease, and the flour will be better. At the same time, the moisture content of each wheat production will increase accordingly, and the profit of flour companies will increase. Because the materials are not easy to separate during sieving, the power consumption is increased, the flour precision is increased, and the ash content is reduced;
4. The roller is the center of the grinding head, and the grinding head is the center of the noodle enterprise. The drawing and sandblasting of the grinding roller cannot be done frequently, especially the regular drawing of the leather grinding and gear rollers, although it can greatly reduce the electric current. However, due to the increase of the shearing degree, the amount of skin mill powder and bran stars will increase, which is not conducive to sieving. This is also the reason for setting up re-sieving. If the problem is over-compressed, the problem will be more serious;
5. The flour outlet of the sifting workshop should be checked frequently. Once it is found that there is material leakage or material leakage, it will easily cause material mixing, thereby increasing the ash content of the flour. The way is to stop the machine, find out the problem, and solve it.
