Sunflower oil is a common vegetable oil that is extracted from sunflower seeds. About The production process of sunflower oil includes multiple steps such as cleaning, shelling, kernel shell separation, cooking, pressing, filtering, and refining.
Sunflower oil is generally produced by two methods: pressing and solvent extraction. The pressing method is a method of obtaining sunflower oil from sunflower seeds by physically pressing them in an oil press, which preserves the natural flavor of sunflower oil. solvent extraction is a production method to extract oil from sunflower seed cake by utilizing the principle of solvent solubility with oil. The residual oil rate of sunflower seed cake after leaching is less than 1%, which improves the yield of sunflower seed oil.
1、How to produce sunflower oil by pressing method?
(1) Firstly, use cleaning equipment to remove impurities in sunflower seeds, common cleaning equipment includes magnetic separator, cleaning sieve and stone remover. Of course, the cleaning equipment needs to be selected according to the actual impurities contained in the sunflower seeds.
(2) Separate the kernel shells of sunflower seeds with a shelling machine, the sunflower seed shells will not only absorb part of the sunflower oil, resulting in the loss of oil, but also the pigment in the sunflower seed shells will be mixed into the oil, resulting in the dark color of the gross oil, so we recommend removing it.
(3)Adjust the temperature and humidity of sunflower seeds by using flaker and cooker to improve the production efficiency of sunflower oil.
(4) Use sunflower oil press to press sunflower oil from sunflower seeds, if you want to speed up the oil production, you can choose pre-pressing machine and press for secondary pressing to produce more sunflower oil.
2、How to produce sunflower oil by solvent extraction method?
The production of sunflower oil by solvent extraction method still needs cleaning equipment, shelling machine, embryo press, steam frying pot, etc. to process sunflower seeds, adjust the internal structure of sunflower seeds, improve the productivity of sunflower oil, only the oil extraction link to make changes.
Sunflower oil and sunflower seed cake can be obtained by using pre-pressing machine, and then the sunflower seed cake is transported to the solvent extraction workshop for solvent extraction of sunflower oil.
The solvent extraction workshop consists of four systems: sunflower oil extraction system, wet powder desolventization system, mixed oil treatment system and solvent recovery system. The workshop is fully automatic with high production efficiency and high oil yield. Most of the large-scale edible oil production plants use leaching method to produce sunflower oil.
Sunflower oil produced by both pressing and solvent extraction methods is collectively referred to as crude oil. Sunflower seed oil contains impurities and is not good for preservation, so if you want to sell sunflower seed oil in the market, you need to refine the oil to meet the relevant standards of sunflower seed oil.
