As one of the most produced grain in the world, corn has been a staple food in many parts of the world. Its application has also extended to animal feed, ethanol and biofuel etc.. Corn milling process can be used as the production process for ethanol extraction from starch or grits, meal, flour, and other co-products. And you can start the corn milling business with comparatively small start-up capital investment.

Sifting(with aspiration), De-stoning, Magnetic Separating 
Separators commonly used: separators including Vibrating Separator, Plane Rotary Separator and Rotary Separator. They are used to remove large, medium and small impurities from corn. Usually, the separators are equipped with aspiration channels to remove light impurities as well.
De-stoner and Gravity De-stoner are used to remove stones and other mineral impurities with bigger specific gravity. There can be one or two rounds of destining depending on the impurity content in corn. In terms of use, gravity de-stoner can remove stones as well as light impurities. 
Magnetic Separating:
Permanent Magnetic Barrels are often used to remove iron impurities in corn.
Tempering Process
Tempering Process:
Dampener: It adds the right amount of water to corn and mix it evenly.
Tempering bin: After the addition of water, the corn will be stored in the tempering bin to soak for a certain period of time to facilitate the milling process.
Corn Milling Process
Corn Milling Process:
Debranning—Degerming—Grading—Germ Separation—Crushing—Milling—Sifting—Finished Product
Debranner: In terms of roller types, debranner can be classified as emery roll debranner and iron-roll debranner. They may come as vertical and horizontal according to the layout of drive shaft.
Its main function is to peel off the skin and also remove the germ of corn. It is generally equipped with an aspiration system to remove the skin and germ that had been peeled off through suction.
Degerminator: The degerminator utilizes the impact between the beating board and the toothed plate, and the friction and crash between corn kernels. It damages the structure of corn germs and the bonding strength between germ and endosperm. Under the combined action of these forces, the corn kernel disintegrate, the corn germ and endosperm can be separated.
Grading Separator: The corn treated by degerminator contain mixture of corn grits of different size, corn flour and corn germ. The grading separator is used to distribute the mixture of different sizes to the grinder and other equipment for further processing.
Embryo Selector: It is used to separate the germ from the endosperm according to the different specific gravity. The purified endosperm enters the crusher to be processed as corn grits or enters the mill to be grinded into corn flour.
Corn Crusher: It is used to break the purified corn endosperm into smaller particles in order to meet the user's requirements for the fineness of corn grits.
Corn Milling Machine: For customers whose main product is corn flour, the milling machine can be used to process corn grits into flour of the desired fineness.
Sifter: The ground material is sifted to extract the finished product of desired fineness. Meanwhile, through screening, some of the corn skin and embryo can be removed hence the end product is purified.
Measuring & packaging
Measuring and packaging section
The warehouse can reduce the amount of labour used. Measuring and packaging can adopt manual or electrical measuring and packaging according to actual needs.
