Working priciple

Generally, sunflower oil production line does the following manufacturing processes: cleaning of the seeds, grinding of the seeds, pressing and extracting crude oil from these seeds, and then further refining the oil obtained before packaging.
Cleaning the Seeds
The harvested oil-bearing seeds are passed over magnets to remove any metal traces, and other impurities are being got rid of by cleaning sieve and destoners. Then the outer covering (hulls) of the seeds are removed to obtain pure seeds.
Grinding the Seeds
The de-hulled seeds are ground into coarse meal to provide a larger surface area to be pressed. Hammer mills or grooved rollers are used to crush the coarse meal into uniform fine particles. Then the meal is heated to enable oil extraction, though impurities are released with oil during this process and such impurities should be removed before the oil is declared edible.
Pressing
The heated meal is fed into a screw oil press which progressively, at the same time, the oil is squeezed out through the slots in the barrel and recovered.
Refining of the Oil
Oil refining involves removal of the bitterness, color, and odor. First, the oil is heated at temperatures between 40 0C and 85 0C. Then it’s mixed with an alkaline substance like sodium carbonate or sodium hydroxide. The oils are degummed by treating them with heated water at temperatures between 85 0C and 95 0C or with acidified water. This precipitates out most of the gums usually phosphatides. Then centrifugation is done to remove the dregs.
