1. Sunflower seed kernel cold pressing (low temperature pressing) process
Sunflower seeds—hulling and separation of shells and kernels—cleaning—rolling embryos—modulating—cold pressing—coarse filtration—filtering—cold pressing crude oil
Sunflower seed oil cold pressing technology is to enter the oil press at a lower temperature after the oil has been tempered. Our company has achieved breakthroughs in sunflower seed dehulling and cold pressing oil production technology through years of process improvements. Reduced energy consumption and reduced operating costs by 6%-11%. The shelled and cold pressed sunflower oil produced by our company’s process and technology has the following characteristics:
1. The oil product has low acid value and light color, which breaks through the problem of benzopyrene produced by hot pressing, and improves the quality of oil;
2. Precise temperature and moisture control ensure the pure and original characteristics of cold-pressed oil and retain the original flavor and color of sunflower oil;
3. Vitamin E in the oil is retained;
4. The refined oil after the follow-up refining and dewaxing process of our company can be used as nutrient oil;
5. By-products such as sunflower seed cake and sunflower seed shell can be fully utilized.
2. Sunflower seed kernel steaming, frying, pressing and oil production process

Sunflower seed oil steaming and frying pressing technology increases the temperature of sunflower seeds entering the press by steaming and frying. Our company’s steaming and frying pressing process can be used for processing sunflower seeds that have high acid value, poor quality and are not suitable for cold pressing. It is an effective process supplement to the cold pressing technology of sunflower seeds. The sunflower oil produced by our company’s process has the following characteristics:
1. It can greatly increase the oil yield of sunflower seeds and reduce the residual oil in the cake;
2. It can obviously increase the flavor of fat;
3. It does not produce harmful substances such as benzopyrene.
3. Sunflower seed pre-expression and extraction process
Sunflower seeds—hulling and separation of shell and kernel—cleaning—rolling embryo—pre-pressing—sunflower seed cake—crushing—leaching—stripping—leaching crude oil
The pre-expression extraction process is suitable for larger tonnage (above 30T/D) projects. This process can obtain two different quality oil products, sunflower seed virgin (high vitamin E content, high quality) and ordinary sunflower oil (extraction) Sunflower seed oil). Products produced using our company’s equipment have the following characteristics:
1. High-quality sunflower seed virgin oil can be obtained. The oil is rich in vitamin E and has high nutritional value. After being refined, it can be used as nutritious edible oil;
2. After pressing the sunflower seed cake, the residual oil of the sunflower seed meal through the extraction process will be reduced to about 1%, and the refined sunflower seed cake will be sold separately as edible oil;
3. The leached sunflower seed meal has the characteristics of low residual oil, which is convenient for the subsequent deep processing of sunflower seed meal such as extraction of chlorogenic acid.
Squeezing and leaching crude oil through the refining process can reduce the gum content in the oil, reduce the acid value of the oil, remove some metal ion sugars and their derivatives, proteins and their degradation products, organic alcohols, pigments, etc., which can effectively extend the oil’s The shelf life prevents the oil from rancidity and reduces the color of the oil, which can effectively expand the application market of sunflower oil.
Our company continues to innovate in science and technology, improve traditional technology, combine modern technology with traditional technology, and develop healthy sunflower seed cold pressing technology in terms of oil extraction, which not only avoids harmful substances produced by traditional hot pressing, but also guarantees the quality of oil. The nutritional value and quality also ensure the oil yield. Larger scale (above 30T/d) can increase the extraction production line at the same time to extract the residual oil from the sunflower seed cake, and reduce the residual oil in the meal to 1% It can significantly increase the economic benefits of oil extraction. The obtained squeezed and extracted crude oil needs to be refined to remove the gum content in the oil, reduce the acid value of the oil, and remove some metal ion sugars and their derivatives, proteins and their degradation products, Organic alcohols, pigments, etc., can effectively extend the shelf life of oils and fats. Our company can perform intermittent, semi-continuous, and continuous refining to meet the needs of various tonnages of oil refining. At the same time, through years of process and technological innovation, it has not only reduced the variety of products compared with peers. The auxiliary materials, water and electricity consumption save costs, and greatly improve the quality of grease, making the quality of grease superior to related production equipment in the industry. We are willing to provide you with a full range of equipment and technical support with professional services.
