  1. 6 Processes of Sunflower Oil Production

  2. Introduction • Best sunflower cooking oil in Chennai begins the following sunflower seed oil production manufacturing processes: • Cleaning the Seeds • Grinding the Seeds • Pressing • Extraction of the Additional Oil • Removal of Solvent Traces • Refining of the Oil

  3. Cleaning the Seeds • The harvested sunflower oil seeds are passed over magnets to removal any metal traces, and other impurities are being get rid off by cleaning sieve and destoners. • Then the outer covering (hulls) of the seeds are removed to obtain pure seeds.

  4. 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.

  5. Pressing • The heated meal is fed into a screw press which progressively increases the pressure from sixty kilopascals (kps) to 950kps, 206kps, to 850kps as the meal is passed through a slotted barrel. • At the same time, the oil is squeezed out through the slots in the barrel and recovered.

  6. Extraction of the Additional Oil • Volatile hydrocarbon solvents are used to process the remaining oil cake through solvent extraction so as to achieve maximum yields. • The most commonly used solvent is hexane which dissolves the oil out of remaining oil cake. • The solvent is then distilled out of the oil, passed through the matter and then collected at the bottom.

  7. Removal of Solvent Traces • Around 90% of the volatile solvent left in the extracted oil, evaporates and it’s collected for reuse. • Then a stripping column is used to retrieve the remaining solvent. • In this process, the oil is boiled by steam and the solvent evaporates, condenses and is collected separately.

  8. Refining of the Oil • Sunflower 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.

  9. Conclusion • Sunflower seed oil one of the best vegetable oil options for healthy eating. • The oil must be extracted to separate it from the solids using one of several processes. • Sunflower meal is a successful substitute for soybean meal in equal protein diets for ruminant animals, as well as for swine and poultry feed. • To have a fresh sunflower meal, there are many refined sunflower oils in Chennai.
