How corn oil is processed: turning corn into liquid gold

How to turn corn into liquid gold? Processing corn oil usually uses pressing method, including corn germ separation, corn germ pretreatment, corn oil pressing and corn oil refining processes. Next, Henan Glory Company will introduce them one by one.

Step 1: Corn germ separation

If your raw material is corn, corn oil production will begin with corn germ separation. The valuable oil-containing part of the corn needs to be carefully extracted from the rest of the corn kernel. It will use high-performance degermination machines. But if your raw material is corn germ that is from starch plant or alcohol factory, it doesn't need this step.

Step 2: Corn germ pretreatment

In the pretreatment process, the corn germ will be processed by vibrating screen, magnetic separator, softening machine, flaking machine and cooking machine. The aim of pretreatment process is to adjust corn germ to the best condition for the pressing process, so as to get biggest oil yield rate.
