How to extract the most oil from sunflower seeds?

In sunflower seeds oil production process, if you want to extract the most oil from sunflower seeds, you can increase the oil yield rate or decrease the residual oil rate by different methods.

Firstly, you had better use high quality raw materials. The oil content of sunflower seeds is about 50%-65%. If there are many impurities in the sunflower seeds, the oil content will be lower theoretically. So using the sunflower seeds with less impurities can make sure higher oil yield rate.

Secondly, if the daily processing capacity is large, you had better use sunflower seeds shelling and kernel & shell separating machine to remove the sunflower seeds shell. Because the shells of sunflower seeds will absorb some oil when pressing, which will increase the residual oil rate.

Thirdly, if you choose to use pressing method, it is better to equip as many as sunflower seeds pretreatment equipment. Like flaking machine and cooking machine, they can adjust the sunflower seeds into best condition for pressing, which can increase the oil yield rate. Another one thing you can do is to use several small oil presser to replace a large oil presser, which can decrease the residual oil rate. Because the residual oil rate of big capacity oil presser is a little higher than the smaller capacity oil presser. [Related reading: sunflower oil pressing line]
