Background

The flour mill (also called flour milling machine) is mainly used for processing grain crops such as wheat, corn and the like, grinding the grain crops into flour, and then sieving the flour and the bran to separate the flour from the bran. The flour mill is the main equipment for milling the coarse cereals such as wheat and corn, and the roller type, the cone type and the disc type (steel mill) are commonly used. The working principle of the wheat flour and bran flour is that wheat and the like are ground into powder by using an extrusion and grinding method, and then the flour and the bran are separated by using a fine sieve.

The disc type flour mill is evolved from a traditional stone mill, manpower or animal power is used as power or a motor, two layers of planes of parallel linear grinding tooth grooves of eight-zone and ten-zone oblique line type partitions in a radiation mode are used, two layers of face tooth grooves are the same, the reverse buckling rotation direction of an upper layer face is opposite to that of a lower layer, textures are arranged at the joint of the two layers, in the actual grinding process, through the parallel operation of grinding discs, the lower disc is static when the stone mill works, an upper disc rolls, food materials enter the middle of the two layers from holes above and move outwards along the textures, and the grinding and refining effects are achieved when the materials roll through the two layers of face fitting friction.

And the disc type pulverizer has low working efficiency in the actual use process, 20-30 revolutions per minute, short service life of a single time and incapability of reaching the grinding fineness standard due to the limitations of low rotating speed and design texture. When the stone mill is used for grinding, the two layers of grinding discs are attached and rubbed to enable the main material to be abraded to generate a large amount of stone powder, and the stone powder and the refined material cannot be separated after being mixed, so that various stones and unpredictable carcinogenic diseases are caused after the stone mill is directly ingested.

And the common disc type flour mills rotate on the upper disc, the upper disc and the lower disc are inevitably collided under the action of gravity, so that corresponding stone powder or iron powder is generated, meanwhile, the upper disc and the lower disc are contacted to generate high temperature, nutrient trace elements of food materials can cause the food materials to be burnt, and strong carcinogen benzopyrene in the burnt food materials can induce gastric cancer, lung cancer, laryngeal cancer, nasopharyngeal cancer, oral cancer, esophageal cancer and unpredictable various carcinogenic sources. Meanwhile, the finished product needs to be cooled by naked air blowing due to high temperature, and secondary serious pollution of the finished product and serious standard exceeding of escherichia coli are also formed.
