Extraction method for oil production is one of the common processing methods in the edible oil processing industry today. Projects using the extraction method are usually large-scale, such as those with a daily output of more than 30 tons, which are suitable for extraction oil production. Common projects using extraction equipment include soybean oil, rapeseed oil, cottonseed oil, rice bran oil, and other extraction oil projects.

The extraction oil production process can be divided into direct extraction and pre-press extraction. The choice of process depends on the oil content of the raw materials. For materials with low oil content, such as soybeans and rice bran, the direct extraction process can maximize oil extraction. For materials with high oil content, such as rapeseed and peanuts, the pre-press extraction method can be used. First, 80% to 89% of the oil is pressed out using an oil press, and then the pressed cake is crushed and sent to the extraction equipment to extract the remaining oil.

Sunflower seed oil extraction equipment and its extraction process have significant advantages in oil extraction, mainly reflected in the following aspects:

1. High Oil Yield:

 The extraction process uses organic solvents (such as No. 6 light gasoline) to fully extract the oil from sunflower seeds, resulting in a relatively high oil yield and more comprehensive utilization of raw materials.

2. High Production Efficiency:

 The extraction process is suitable for large-scale production, with continuous operation and a high degree of automation, greatly improving production efficiency to meet market demand.

3. Stable Oil Quality: 

By precisely controlling operating parameters such as temperature, solvent type, and concentration, the extraction process ensures that the extracted sunflower seed oil is of stable quality and meets standards.

4. Low Residual Oil Rate: 

Compared to other processes, the extraction process can more thoroughly extract the oil from sunflower seeds, resulting in a lower residual oil rate in the cake, improving raw material utilization.

5. High Economic Efficiency: 

The extraction process can almost completely extract all the oil from the raw materials, resulting in very high economic efficiency, making it a popular processing method in the modern oil industry.

In summary, sunflower seed oil extraction equipment and its extraction process have significant advantages in the field of oil extraction, improving production efficiency, reducing costs, ensuring oil quality, and meeting the needs of large-scale production.
