Corn processing machine

80%-90% of corn is used to process corn grits and corn flour, and 10% of corn as corn germ is used to process corn germ oil.If this , nearly all corn will be utilized,75%-80% is corn grits and corn flour, 3.5% is corn oil and the residue is feed powder.

Process of corn grits and flour

1. Cleaning.The first step is screen selection, remove big and small impurities from corns with vibration cleaning screen,and remove stons and other heavy impurities with stoner in the second step,so as to get clean corns.

2. Peeling. Peel the corn husk twice , corn will be graded and corn husk will be conveyed to another workshop for feed powder.

3. Pelleting. Process whole corns into pellets.

4. Peeling and polishing. Peel corns clean and polish them.

5. Separate big corn grits, middle corn grits and small corn grits with high efficency grading sieve.

6. If process corn flour, grind them into flour and grade them.

Process of corn oil

1. Extract corn germs

2. Clean corn germ can be pressed into oil direct,otherwise,clean them to remove impurities.

3. If processing capacity of corn germ is big, pre-press them to get part of oil firstly and then extract residual oil in cake.

4. Refine crude corn oil into cooking oil/edible oil.

Such technology is reasonble to process corns, on the one hand ,the finished products are corn grits and corn flour, by-product as feed flour.On the another hand, corn germ is also utilized to process corn oil.
