However, large scale sunflower oil mill plant need consider every part whether there is waste. So husking can prevent the shell from absorbing the sunflower oil in sunflower oil making process so as to reduce the residual oil rate.

After husking, the color, acid value and wax content in crude sunflower oil are all reduced. Most important thing is that it not only improve the protein content of sunflower seeds meal, but also reduce the antinutritional factors from sunflower seeds shell, so that the sunflower seeds meal is more suitable as animal feed.
