Sunflower oil introduction:
Sunflower oil a kind of golden color, clear and transparent, fragrance oil, is an important edible oil. It contains a lot of linoleic acid and other essential unsaturated fatty acids, can promote the regeneration and growth of human cells to protect skin health, and can reduce the deposition of cholesterol in the blood, it is an advanced nutritional oil.Sunflower oil solidified low point, easily absorbed. Role sunflower oil also contains more vitamin A and carotene, there is treatment of night blindness, prevent cancer, lower serum cholesterol concentrations
The world's largest sunflower oil producers now are Russia, Ukraine and Argentina.
Consumption of sunflower oil in the world in all vegetable oils behind palm oil, soybean oil and rapeseed oil, ranking fourth. Global sunflower oil production has stabilized at between 10 million to 1200 million tonnes, sunflower seed oil is one of the major varieties of edible oil European countries. Internationally, many countries and regions such as Taiwan, Hong Kong, Japan, Korea, sunflower oil consumption ratio up to 70%
How to make sunflower oil from sunflower seeds? Sunflower oil is one of the highly demanded oil around the world. It has been preferred by many people because of the sweet aroma and good smell. While how to make sunflower oil by using sunflower oil mill machinery? Here I will introduce the main process of sunflower oil production.
The sunflower oil processing process:
1. Sunflower oil pre-press process First, using magnetic roller , destoner and cleaning machine to remove metals, small stones , impurities from sunflower raw seeds.
Second, using husking machine to remove husks, separating screen to separate husk and sunflower kernel , here separating screen must not separate completely uf not it will be too slippery for oil pre- press.
Third, cooking sunflower seeds ready for oil pre-press
Fourth, pre-pressing sunflower seeds. here only pre-press part of sunflower oil , oil residue inside cake (about 12-16%) will be extracted in oil extraction process.After pre-pressed, the crude sunflower oil will be delivered directly to sunflower oil refining , and pressed cake to oil extraction.
2. Sunflower oil extraction process First, using solvent to extract oil from sunflower oil cake inside oil extractor, final products are mixed oil and wet meal
Second, the mixed oil will pass through three evaporators to make solvent inside transform into gas , and solvent will be recovered through condensers and reused. These three evaporators are not with same size , the first evaporator is bigger than other two because there are more solvent inside mixed oil in the beginning . After evaporated, we will get crude sunflower oil ready for oil refining.
Third, the wet meal will be delivered to desolventizer to dry and be separated with solvent . The dry meal will be packaged for sale as animal feed.
Note: Sunflower oil extraction is more and more important in oil processing , because oil residue inside meal is less than 1% much less than oil residue inside cake without extraction.
3. Sunflower oil refining process First , hydrated degumming, mainly is to remove phosphatide inside crude sunflower oil in order to reduce oil loss and improve quality of oil .
Second, alkali refining, using alkali to neutralize free fatty acid with by-product of soapstock ,which is used for making soap.
Third, decoloration using bleaching clay to absorb darker colorant inside crude oil.
Fourth, deodorization is using high temparature to remove the impurities with bad smell .
Fifth, dewaxing is using low temperature to freeze wax inside refined oil and then separate wax with vibrating screen.
4.Sunflower oil filling machine
After refine,you will get first-grade edible sunflower oil,u can fill it into bottles,or bags,then sell it to supermarket directly
