Corn, it is also one kind of very important grain crops, it originated from North America and Latin America. Now it has been widely planted in the whole world. In the content, corn has higher protein, fattiness and Phosphorus, Calcium, Magnesium, Ferrum, mineral matter and vitamin on chemical composition. The detail content should be as follows,

• Nutrient content
• Nutrient per 100.0g
• Quantity of heat(calories): 332.0
• Carbohydrate(g): 72.2
• Fattiness(g): 4.3
• Protein(g): 8.5
• Fibrin(g): 1.2
• Vitamine: E, A, B1, B2, B6
• Phosphorus: 120mg, Calcium: 22mg, Ferrum: 1.6mg

China is the world’s second largest corn producer. The largest corn plant area in China, they will be Heilongjiang, Jilin, Liaoning, Inner Mongolia, Shanxi, Hebei, Gansu and so on.

Spring corn, it will be planted for once per year in the North of China. The largest production by province in China: Heilongjiang, Jilin, Liaoning, Inner Mongolia,Shanxi and Hebei. Sweet corn, Guangdong has been largest hardiness zone in the wolrd at present. Its total plant area will be the 9% of the whole world and the 1/3 of China.

World corn production( FAO reported in 2007) (Unit:100 million tons): United States America: 332.09 China: 151.97 Brazil: 151.59 Mexico: 22.5 Argentina: 21.75 Indonesia: 16.78 France: 13.10 India: 12.38 Canada: 10.55

China corn production(Unit:100 million tons): 2004: 115.4 2005: 122 2006: 144 2007: 152.93 2008: 165.5

Corn production by country: United States America, China, Brazil, Mexico, Argentina, Inonesia, France, India and Canada.

Corn Harvest: With the development of moden industry, corn harvest has also been realized into automatic harvest by combine harvester. Of course, in few of countries and area, some farmers still have to need to harvest corn by hand.

However, corn harvest will be different from wheat harvest. Because it will still need corn husker and corn cutter to get corn seed.

Corn Milling: Because of different physical charactor, corn will be processed into corn flour, corn grits, corn germ and corn bran by corn flour milling machine. Its general technology flowchart should be as follows: crude corn storage by silos, corn pre-cleaning section, corn cleaning section, corn milling section, flour, germ and bran packing section and corn products storage section. Final products of corn flour milling line will be 30%~50% corn flour, 50%~30% corn grits, 8%~10% corn germ and 10% corn bran. Corn flour milling line will be different from wheat flour milling line. During cleaning section, corn will need pre-crushing and it will also separate germ from crushed corn by degermer or embroy selector. During milling section, corn germ or embroy will still need classifying or sifting. At the same time, corn grits and corn flour will also be separated out of the mixture with flour, grits and bran. About more corn milling technology, we will have the detail introduction on our website, too.
