In recent years the demand for sunflower oil has increased drastically. And why not? Sunflower oil is preferred throughout the world for its attractive color, light flavour, high smoke point and rich unsaturated fatty acids. With our sunflower oil processing plant, you can capitalise on this demand. How? It’s easier than you might think.
1.Capacity: 10-1000TPD sunflower seed
2.The quality standard of finished oil: the first grade edible oil
3. Other byproducts of the oil plant: Sunflower oil meal, soapstock, foot oil, wax
The main workshop in sunflower oil making plant
1. Pretreatment / prepress Workshop
The process begins with cleaning. Magnets are used in order to remove any trace metal, and the seeds are scrubbed of any foreign matter. If the moisture content of the seeds is too high it will have an adverse effect on the sunflower oil produced, so we dehull. The seeds are cracked by a pneumatic or centrifugal sheller, and the result is winnowed to separate kernel from hull.
Quality requirement of raw material
Acid value: ≤0.8 (KOH) / (mg / g)
Epigranular: all without mildew.
Sunflower Oil Pressing:
Oil Pressing Factory of Seed Oil Mill Plant
2. Solvent Extraction Workshop
Main processing flow
Solvent extraction plant is obtained from the pretreatment & prepress plant embryo or pie slice to get the crude oil extraction withnormal hexane extraction process. Production processes include the leaching step, wet meal off steam process, mixed oil evaporation process, the solvent recovery process.
Cake moisture: 5-8%
Oil percentage: 8-16%
Capacity ≥80 TPD
Product quality index :
Meal remain oil ≤1.2%
Meal moisture content: 11-13% can be adjusted
Meal solvent percentage ≤ 500PPM
B. Extracted crude oil:
Total volatile matter ≤ 0.2%
Solvent remain ≤ 100PPM
Mechanical impurities ≤ 0.2%
Economic and technical index
Steam consumption ≤ 300kg/ton cake
Power consumption ≤ 15KWH/ton cake
Solvent consumption ≤ 2kg/ton cake (solvent with international standard)
3. Refinery Plant
Mainly contains the following section: section of deacidification and degumming, section of decolorization,section of deodorization, section ofdewaxing.
After solvent extraction, the crude oil can be collected and refined in oil refinery plant. This involves heating the oil to between 40℃ and 85℃ and mixing it with an alkaline substance such as sodium hydroxide or sodium carbonate. Together with this additive, the undesired fatty acids form a soapy substance that is then removed using centrifugal force. The oil is cleaned to remove any traces and dried. It is then degummed, the oil treated with acidic water or steam to remove hosphatides. Once again, centrifugal force is used to remove any dregs.

Oil that will be used for cooking is then bleached by filtering it through activated clay or fuller’s earth, substances which can absorb pigmented materials from the oil. Oils that will be refrigerated are filtered to remove waxes. The final step is deodorizing the oil. The oil is placed in a vacuum at 225C to 250C, over which steam is passed to distill any odor or volatile components. A tiny amount of citric acid might also be added to increase the oil's shelf life. Once this is complete, the finished oil can be packed and shipped to shelves across the world. Further with dewaxing, the produced oil is with top quality in world.
