FAQ about vegetable oil processing technology

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.
