When we mentioned sunflowers, we may think of edible sunflower seeds and sunflower seed oil, which is closely related to our diet. But do you know the production process of sunflower seed oil? Let me explain it to you next.
1. The introduction of raw materials--sunflower seeds
Sunflower seeds are rich in unsaturated fatty acids, vitamins and trace elements. They are the raw materials of some popular snacks and edible oil. In common, the sunflower seeds can be divided into edible sunflower seeds and oil sunflower seeds. The oil sunflower seeds that usually used to make sunflower oil are with small grain, full seeds, thin shells and high kernel rate, that is about 65% ~ 75%. And the oil content of oil sunflower seeds with shells generally reaches 45% ~ 54% while the edible can only reach 22%-35%. The oil content of oil sunflower seeds without shells can reach 45%-60% while the edible can reach 40%-50%. So when the sunflower seeds be pressed, it is better to use sunflower seeds without shells, which means it needs husking before pressing.
For example, in sunflower seed oil production process, if you want to process 100 ton oil sunflower seeds without shells, you may get 45-60 ton oil and if you want to process 100 ton edible sunflower seeds without shells, you may get 40-50 ton oil. We can see the oil content in oil sunflower seeds is more than that in the edible.
2. The specific production process of sunflower seed oil
In fact, the whole sunflower seed oil production process is simple and can be divided into three steps.
The sunflower seeds pretreatment and pressing process
The crude sunflower oil refining process
The sunflower oil dewaxing process
Detailed sunflower seed oil production process:
Oil seeds--magnetic separating--destoner--husking--crushing--flaking--cooking--pressing--filtering--crude oil--degumming--deacidification-- decolorization--deodorization--filtering--dewaxing--flitering--edible oil
Sunflower pretreatment machines
The sunflower seeds pretreatment is mainly to improve the oil yield and quality of sunflower seeds by basic cleaning in sunflower seed oil production process. First of all, remove stones, iron and shells to make the oil rate reached the highest and the oil residual lowest (It can use degusting equipment if the dust is too large, which depends on different raw materials). Collect the kernels without shells by using kernel husking and separating equipment. Then crush, flake, cook, and press. In this way, it can ensure the oil yield and quality of sunflower oil, meanwhile it also can extend the using life time of the machines. The crude sunflower oil we got through such a phase can eat after simple precipitation and filtration.

Sunflower oil refining machine
But if we want to sell the sunflower oil to the market as a brand, the oil quality must meet the requirements of the national standard. So the whole sunflower seed oil production process should include a set of sunflower oil refining machine. The process of sunflower oil refining includes four stages, that is degumming, deacidification, decolorization and deodorization.

Sunflower oil dewaxing machine
The last is sunflower oil dewaxing in sunflower seed oil production process. The wax ingredient in sunflower oil is 0.06%-0.2%. By taking advantage of different composition have different crystallization temperature, separate out crystal wax. Finally we get the edible oil that meets the national standard requirements of food sales after filtering.

The above is the whole production process of sunflower seed oil. In recent two years, many people began to enter the cooking oil industry to become one of them with the cooking oil industry becoming warm. I hope this article can help you know more details about sunflower seed oil production process!
