Corn Grits Flour & Germ Solutions

The complete set of corn grits, flour milling and germ extraction adopts the domestic advanced new dry process technology. This design is widely used in food, sugar, beer and oil companies.

Finished Products

The process uses the domestic advanced new type of dry corn refinement processing line design. Ensure that the genuine gain rate and product quality of various products meet or surpass national standards. The finished product structures are grade corn flour, grade corn crickets, corn germ, fine feed and other products.

Process Flow

The co-production process of corn grits making, flour milling and germ extraction includes the following steps: impurity removal, cleaning, peeling, degerming, grits making, grading, flour milling, sieving, and packaging. Using this processing technology can significantly improve the specifications and quality of corn finished products at all levels, and the finished corn products are of superior quality, rich aroma and improved taste.

01.Intake and precleaning

Intake and precleaning

Pre-cleaning is key for an efficient and safe milling process. Grain contains impurities and foreign matter. Removing impurities prior to storage extends the life of machinery and creates hygienic storage conditions for your grain.



Cleaning various impurities, defective materials and pollutants of corn seeds.We offer mechanical destoners, separators and color sorters.

03.Corn peeling and degermining

Corn peeling and degermining

Degermination separates bran, germ and endosperm for flaking and milling. Our grain cleaners gently process the corn, neatly separating the germ, epidermis and endosperm with minimal fines.

04.Flour milling

Flour milling

Roller mills grind the degerminated corn grits into semolina and flour. Sifters then separate the coarse and floury particles. Purifiers improve this separation process. Cleaning reduces specks in the semolina.
→   Smart Pneumatic Roller Mill →   NF Series Grain Mills

05.Corn flour

Corn flour

The corn flour produced by the whole process has a higher quality standard and a high yield rate, which reduces food waste, and the separated germ can also be used in oil factories.

06.Unloading and packing

Unloading and packing

The finished products are either bagged or loaded in bulk. Here it is important to keep dust to a minimum. Precise dosing and weighing are also key. We offer a wide range of manual and fully automated loading and bagging systems

  • Moisturizing system

    In the original traditional dry corn processing technology, a corn watering mixer was introduced and placed behind two emery roller peeling machines, which neither affected the moisture in the corn hulls nor changed the quality of the by-product feed, but also reduced the corn The combination degree of germ, endosperm and epidermis is better for peeling and degerming during the peeling and polishing process of the subsequent iron roller polisher. At the same time, the heat generated during the polishing process will take away the water, thereby reducing grain consumption. According to the actual calculation of the production line, compared with the full dry process, the yield can be significantly increased by 1-1.5 percentage points.

  • Three polishing

    In view of the two polishing and embryo selection processes of the traditional corn processing technology, our new technology is the first to abandon the embryo selection machine. In the original process, the germ separator relies on the specific gravity to separate the germ and endosperm through the suspension of the material, and it is inevitable to bring in some endosperm containing broken embryos, or select some broken embryos containing endosperm; at the same time, the specific gravity selects the embryo The air volume of the machine needs to be adjusted according to the specific separation conditions of germ and endosperm on site, which requires high skill of the operator and makes the operation difficult. In the new process, a polishing machine is added after the original two polishing machines to perform secondary polishing on the endosperm containing broken embryos after screening and grading, so as to solve the problem of broken embryos in the finished product and ensure the purity of the endosperm for subsequent processing.

  • Multi-channel suction

    Different from the traditional dry corn processing technology, the new technology adds multi-channel suction separator, which does not increase the power of the whole set of equipment, but also performs suction of skin, floating powder, suction of crushed embryos, and removal of black stars for each peeling and polishing process, and at the same time , before the finished product is packaged, the skin is sucked, the powder is floated, the embryo is sucked, and the black star is removed. It ensures that the packaged finished product has no micro skin, no broken embryos, no black stars, and also reduces equipment investment.

  • Secondary dust suppression

    All dust removal in this process adopts the working principle of secondary dust removal. Through the mutual cooperation of the brake dragon dust removal and pulse dust removal, it not only reduces the workload of the pulse dust collector, but also ensures that there is no leakage of dust in the production line, which fully meets and exceeds the current requirements.
