Simply speaking, in cooking oil manufacturing process, a series of machines are used, such as cleaning machine, cracking machine, flaking machine, cooking machine, cooking oil press machine, cooking oil solvent extraction machine and cooking oil refining machine. But different oil seeds need different machines to pretreat before pressing or solvent extraction because of their special features.
Groundnut and sunflower seed are both with shell and belong to high oil content oil seeds. So they need shelling machine after cleaning.

And they are better to use pre-pressing and solvent extraction method instead of pressing straightly. In this way, you will get more oil than oil pressing method.

Because it is difficult to control its moisture content and temperature. If moisture content high, corn germ will too thick, or it will too dry vice versa. Both states are not proper to press.
