In the millet processing machinery, the parts in contact with the millet will use more alloy and non-metal materials to prevent rust and ensure the cleanliness of the finished grain;
The process flow of Millet processing can be divided into two categories:
Machinery and equipment for cleaning, dehulling, peeling or grinding and screening raw grains to make them into granular or powdered finished grains of different grades.
The first process is to shell and peel raw grains such as rice, sorghum, millet, and millet, and grind them into granular finished grains;
The second process is to make millet flour from dehulled and peeled millet
Millet processing is similar to the process of rice processing.
Millet is firstly cleaned by a cylinder, and then through a reciprocating vibrating screen, a high-speed vibrating screen, a specific gravity stoner and a magnetic separation equipment to remove various impurities, and then enters the rice husker to remove and separate the rice husks. The discharged mille and millet husker mixture is sent to the grain separator. Using the difference between millet and husk in particle size, specific gravity, friction coefficient and elasticity, separate the unhulled millet and send it back to the husker;
Brown rice is milled into white rice in a rice mill. Then, after finishing the finished product, remove the millet, and get the finished millet. Millet millet is commonly used in rural China to directly process millet into pearl millet, but the output is low and broken. When making special or flour, a purifier is also used to separate pure and relatively pure endosperm particles from the intermediate material discharged from the mill and flat sieve, and further grind into special and flour.
The development trend of millet processing machinery
In the millet processing machinery, the parts in contact with the millet will use more alloy and non-metal materials to prevent rust and ensure the cleanliness of the finished grain; the frame will use light metal and thin-walled steel structure to reduce weight, and try to use the interior of the equipment as much as possible Spatial arrangement of components to reduce volume.
The service life and interchangeability of working parts and moving parts will be further improved, while the number of fastening points and parts will be simplified and reduced to shorten the assembly and disassembly time of working parts and reduce loose parts. One machine with multiple functions and automatic control and protection devices for equipment will be further developed. In addition, millet polishing equipment also has a promising future because millet can be milled to obtain millet finished products with good color and luster.
