The crude sunflower oil obtained either from sunflower oil pretreatment and pressing workshop or sunflower oil solvent extraction plant contains impurities, which must be removed to make the oil edible, more palatable and stable against rancidity upon storage. Small scale sunflower oil refinery plant refers to a series of refining processes that can remove phospholipids, FFA, pigment, off-flavor and other impurities in the oil.The process of removing these impurities after oil extraction section is called oil refining.
Small scale sunflower oil refinery plant
Small scale sunflower oil refinery plant usually includes the following sections: Degumming,Neutralization, Bleaching, Dewaxing and Deodorization.Following are the main steps of sunflower oil refinery process.
Small scale sunflower oil refinery process: Crude sunflower oil→Degumming process →Deacidification process →Decolorization process → Deodorization process → refined sunflower oil
Sunflower oil refinery process
Main process of small scale sunflower oil refinery plant Degumming Degumming reduces the phosphatides content in some crude oils (soybean, sunflower, rapeseed etc) Neutralizing The free acids contain in oil can be either alkali neutralize. Most oils can be "physically" neutralize in the deodoriser render this alkali treatment unnecessary Bleaching During this operation of sunflower oil refinery plant most colouring pigments are removed by absorption bleaching earth. Deodorizing Odour and taste are removed under special condition (high temperature and sparge steam) in sunflower oil refinery plant.

Description of sunflower oil making machine: 1. Sunflower oil pretreatment and pressing machine introduction:
First, using 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.
Third, crushing , softening , falaking, cooking sunflower seeds ready for sunflower oil pre-pressing process.
Fourth, pre-pressing sunflower seeds. here only pre-press part of sunflower oil , oil residue inside cake (about 12-16%) will be extracted in sunflower oil extraction process.After pre-pressed, the crude sunflower oil will be delivered directly to sunflower oil refining workshop, and pressed cake to sunflower oil extraction workshop.
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.

Crude sunflower oil → degumming →deacidification → decolorization → deodorization → dewaxing → final sunflower oil
Sunflower oil refining process
Sunflower oil refining process description:
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 diaphragm filter.
