Q:How to Make Refined Sunflower Oil?
A:Sunflower oil is rich in linoleic acid (54% to 70% of total fatty acid content) and oleic acid (about 39%). The nutritional value is high, but the crude oil contains trace amounts of wax (about 0.10%) and oxygen acid, which affecting its quality and storage stability. Sunflower oil refining process basically includes degumming, deacidification, decolorization and deodorization, which is similar to soybean oil refining. Besides, in order to remove the wax contained in sunflower oil, there often has the process of dewaxing to get higher-grade edible oil.
Q:How to Check Oil Cake by Screw Oil Press?
A:When the screw oil press machine works, the oil cake expelled is a very important indicator for the oil output rate. In order to achieve the optimal oil output rate, it is highly recommended to check the oil cake regularly when it in operation.
Normal Oil Cake: The normal cake produced by screw oil press should be in the form of a tile, smooth on the side of the screw axis, and a lot of scratch on the other side.
Abnormal Oil Cake: The cake is loose and weak, or the cake is not shaped. The color of the cake is deeper and it is made into pieces by hand.
