Sunflower oil is a kind of high nutritional edible oil with large market demand and broad investment prospects. The sunflower oil production plant adopts advanced physical pressing technology and refining equipment and makes the first-grade sunflower oil, which can be directly sold. The processing steps of the sunflower oil production line mainly include roasting, pressing, filtering, refining and filling. The production line has a high degree of automation, various outputs, and high oil quality. The sunflower oil processing machine is suitable for small and medium-sized oil extraction factories or workshops.

Sunflower oil and industrial process overview
Because sunflower oil contains about 66% “linoleic acid”, it is known as the “healthy nutritional oil” in the 21st century, and its nutritional value is extremely high. It has the effect of lowering blood cholesterol, preventing and curing atherosclerosis and cardiovascular diseases. Sunflower seeds can be extracted from high-grade edible sunflower oil with low cholesterol.
Sunflower seeds are mainly divided into ordinary sunflower seeds and oil sunflower seeds. Ordinary sunflower seeds are processed into dried fruits for sale, and oil sunflower seeds are more suitable for processing and extracting sunflower oil. The processing of sunflower oil, due to its high oil content, is usually carried out in the industry by pressing techniques. According to the different quality and oil content of oil sunflower in different places, the oil yield of sunflower seeds (oil sunflower) is 32%-42%. From the perspective of oil processing equipment, it is mainly a matter of choosing a sunflower seed oil press and refining equipment.
Introduction to sunflower oil production plant and features
There are two ways to squeeze sunflower oil from sunflower seeds: cold pressing and hot pressing. Cold pressing is to directly press sunflower seeds with a sunflower oil press after pretreatment, but the oil yield of cold-pressed oil is not high. Also, the oil produced is not rich in flavor, and water content is high, not easy to store. Hot pressing has one more roasting process than cold pressing, so the hot-pressed sunflower oil has a higher oil yield and a stronger fragrance. In the sunflower oil processing industry, the hot pressing method is usually used with the sunflower seed roaster machine. Hot pressing sunflower oil with a screw press is more common, and the actual oil quality is good.
The refining of sunflower oil is equally important. The sunflower oil preliminarily squeezed by the oil press is not recommended to be eaten directly, and it does not meet the national standard for sunflower seed edible oil. Crude sunflower oil contains some impurities, including peptizing impurities, free fatty acids, pigments, odors, waxes, etc. Crude sunflower oil needs to be refined to obtain high-quality sunflower oil that meets national standards. It can only be sold to some retail investors or oil mills for further processing. To produce high-quality first-class sunflower oil and expand sales, sunflower oil refining equipment is essential.
What are the general sunflower oil processing steps?
- Step 1, Rosting (Heat Treatment)
Heat treatment is one of the most important processes in the process of extracting oils and fats. Materials that are pressed after roasting are called hot pressing, and those that are not subjected to heat treatment are called cold pressing. Sunflower seeds are mainly hot pressed, and the effect of heat treatment has a direct impact on the smooth progress of the entire oil production process, the level of oil yield, and the quality of oil products and cakes. It is best to choose the oil sunflower seeds that are one month after harvesting. The hot pressed oil sunflower can be pressed evenly when it reaches 70% or 80% roasting degree, with the highest oil yield and very fragrant oil.
- Step 2, Pressing
The round bar of the sunflower oil press in the sunflower oil production plant has a zigzag curve and a conical surface. When the oil sunflower is pressed, it is pushed and squeezed by the squeezing snail, so that the inner wall space of the squeezing snail and the squeezing cage is continuously reduced. The blanks are alternately pressed and loosened here, and the structure of the blanks is continuously adjusted to be evenly turned, so that the unpressed oil or the blanks with less oil have more chances to be fully pressed.
- Step 3, Filtering
The sunflower oil squeezed by the automatic sunflower oil press contains a certain amount of oil residue. In order to improve its purity, the sunflower oil machine is equipped with two vacuum oil filter barrels. The filtered oil has less oil foam, and it is clear and translucent, and the oil fragrance is overflowing.
- Step 4, Refining
The refining process of sunflower oil in the sunflower oil production plant mainly includes five parts: degumming, deacidification, decolorization, and deodorization (dewaxing). The function of degumming is to remove peptizing impurities from the crude sunflower oil. Deacidification works by removing free fatty acids from hairy sunflower oil. Free fatty acids can lead to rancidity in sunflower oil. The function of decolorization is to remove the pigment in the hairy sunflower oil, so that the color meets the national standard. The function of deodorization is to remove the odor in the hairy sunflower oil. The function of dewaxing is to remove the wax in the hairy sunflower oil and improve the quality of the oil.
- Step 5, filling
Fully automatic sunflower oil filling machines ensure efficient and precise filling. The automatic oil packaging machine meets food processing safety standards and saves great labor.
