On March 11, 2024, a Polish company ordered Huatai Group's 100TPD sunflower seed cake extraction project to start shipping.


When it comes to sunflower seeds, I believe everyone will be familiar with it. Sunflower seeds are the fruit of sunflower. Sunflower is a plant belonging to the genus Helianthus in the Asteraceae family. Sunflowers can be divided into two categories according to their uses, namely oil sunflowers (oil sunflowers) and sunflowers. Edible sunflower (European sunflower). The oil extracted from sunflower seeds can be squeezed into high-grade edible sunflower oil with low cholesterol. Because it contains part of "linoleic acid (ω-6 fatty acid)", it has the effect of lowering blood cholesterol, preventing atherosclerosis and cardiovascular disease. effect.


The extraction method of the sunflower seed cake leaching project is mainly based on the principle of oil leaching. This is a method that uses solid-liquid extraction technology to contact the oil in the sunflower seed cake through a specific organic solvent to extract the oil from the cake. . Specific steps are as follows:

1. Pretreatment: Sunflower seed cake needs to be pretreated before leaching, including crushing, screening, etc., to increase its contact area with the solvent and improve leaching efficiency.

2. Extraction: The pretreated sunflower seed cake is sent to the leaching device and fully mixed with a specific organic solvent. Through the mutual solubility principle of solvent and oil, the oil is extracted from the sunflower seed cake to form a mixed oil.

3. Desolvation and drying of wet meal: After leaching, the wet meal discharged from the leacher contains a certain amount of solvent. In order to recover these solvents and obtain better quality meal, the wet meal is heated to evaporate the solvent.

4. Evaporation and stripping of mixed oil: The solvent in the mixed oil needs to be removed through the process of evaporation and stripping. Evaporation uses heat to vaporize the solvent and reduce the solvent content in the grease. Stripping uses direct steam and indirect steam heating to further evaporate the solvent in the mixed oil.

5. Solvent vapor condensation recovery: The solvent vapor generated during the evaporation and stripping process will pass through the condensation recovery system and condense into liquid solvent to realize solvent recycling.


The advantages of the sunflower seed cake leaching project are mainly reflected in the following aspects:

1. High oil yield: The sunflower seed cake leaching method can efficiently extract the residual oil in the sunflower seed cake through the extraction of organic solvents, thus increasing the oil yield. Compared with the traditional pressing method, the leaching method can make more comprehensive use of raw materials and reduce the waste of oil.

2. Environmental protection and energy saving: The solvent used in the leaching process can be recycled, reducing resource consumption and waste emissions. In addition, leaching equipment is usually equipped with an efficient recovery system, which can maximize the recovery and reuse of solvents and reduce environmental pollution.

3. Excellent oil quality: Sunflower seed oil extracted through the leaching method has a clear color, pure smell, smooth taste, and is rich in unsaturated fatty acids and other nutrients. This high-quality oil meets consumer demand for healthy eating.

4. High economic benefits: The leaching method has high production efficiency and can handle a large amount of sunflower seed cake, so it is suitable for large-scale production. In addition, due to the high oil yield and excellent oil quality, the sunflower seed oil produced by the leaching method has high competitiveness in the market and brings good economic benefits to the enterprise.

6. The process is mature and stable: The oil extraction process of the sunflower seed cake leaching project has been quite mature and stable, and the equipment and technology have been continuously improved, providing reliable technical support for production. This helps reduce production costs, improve production efficiency, and ensure the stability of product quality.

In general, the leaching method has significant advantages in extracting oil, but it also requires attention to safety issues during operation. With the continuous advancement of technology and optimization of the process, the leaching method will play a greater role in the field of oil extraction. , these advantages make the sunflower seed cake leaching method widely used and promoted in the oil industry.
