How Is The Raw Grain Cleaning Of The Flour Machine Carried Out?

The raw grain cleaning part of the flour mill is also known as the wheat room. It has two forms of wet cleaning (installed with a wheat washing and drying machine) and dry cleaning (installed with a stone remover for wheat watering). The wool first flows through the barn grid to separate out extra large debris, such as rope ends, clods, stones, etc., and then lifts up to the unloader. After unloading, it flows into the screen combination cleaning machine to separate out the wheat The size of impurities, and remove the mud, wheat wool, dust on the wheat husk and part of the wheat husk on the surface of the wheat. The cleaned wheat, after being lifted by force and sifted through the sieve, enters the stone remover to remove the side-by-side stones and side-by-side mud blocks in the wheat. If dry cleaning is used, then the raw grain is lifted to the water auger (installed on the wheat moistening bin) by standing up, and the wheat can be moistened after passing through the water; The raw grain is then entered into the wheat washing auger of the wheat washing machine. Under the action of the auger, the side-by-side stones and side-by-side mud blocks in the wheat are further separated, and the surface of the wheat grains and the soil embedded in the wheat ditch are washed away. Pesticides, bacteria, viruses and other sundries are then dried to keep the moisture content of the wheat between 13.5-14.5% (the moisture content of the wheat can be changed by adjusting the watering time), and then it is raised to the wheat moistening warehouse at the end to moisten the wheat. . After the wheat has been moistened for 12-24 hours, the net wheat can be extracted into the flour room for the preparation of grinding flour. During the whole working process of the small and medium-sized flour mill, the air source is provided by the fan. During the unloading process of the unloader, due to the action of the airflow, the light impurities and dust are also separated, which further strengthens the cleaning effect.
