Oil sunflower seeds are the main raw material of sunflower oil, and the fat content of sunflower seeds can reach about 50%. The oil content in the kernel is as high as about 38%~45%. The extracted oil is light in color and has a strong aroma of sunflower seeds. After five de-refining, it can be used as salad oil.
The sunflower oil sold on the market mostly uses the sunflower oil pressing process or pre-pressing-extraction process to produce oils, and its process flow is as follows:
Sunflower oil pressing process:
Sunflower seeds → cleaning and drying → shelling (removing sunflower seed shells) → flaking → cooking → oil pressing (separating sunflower seed cakes) → filtering - crude sunflower seed oil (crude oil);
Sunflower seed pre-pressing-extraction process:
Sunflower seeds → cleaning and drying → shelling → crushing → flaking → cooking → pre-pressing → pre-pressing cakes → extraction → filtering evaporation and stripping → extracting crude oil;
After the crude oil is obtained, it needs to be refined and impurities removed, and "five removals" is a common refining process:
Crude sunflower seed oil → filtration → hydration (degumming) → alkali refining (deacidification) → decolorization and deodorization → dewaxing → finished oil;
The choice of edible oil processing technology is not only related to product positioning, but also to the output size of the oil factory. Generally, cooking oil mills with large output will choose the pre-pressing-extraction process. The pre-pressing-extraction production line uses many equipments and has large output. It is suitable for oil mills with daily processing of more than 30 tons. It can further extract the residual oil in the cake, improve the oil yield and the quality of sunflower seed cake, and create good benefits. Edible oil mills with smaller output are more suitable for the sunflower oil pressing process, and produce first-grade sunflower seed oil with refined oil equipment to make their own edible oil brand, and consider expansion after stabilization.
Investing in an oil mill, a set of high-quality edible oil production lines can provide a lot of help for the subsequent production of the edible oil mill. How to choose a strong and reliable manufacturer to cooperate with among many manufacturers is an important thing for consumers in the early stage. Here we recommend consulting and inspecting the machine at Henan Oil Machinery.
