Soybean oil is an important edible cooking oil globally. It is vegetable oil. Generally, it is produced from the soybean seeds. Here in this article, we intend to explore how to start a soybean oil production business with a processing video.
 
Commercially, there are two methods for producing soyabean oil. You can produce the oil either by pressing or solvent extraction methods. Basically, the screw pressing method is a mechanical process. The process is complicated and the oil yield is much lower.
 
On the other hand, solvent extraction is a chemical process. It ensures a higher oil yield. Therefore, we strongly recommend going with the solvent extraction process.
 
Additionally, you can start the soybean oil production unit in two ways. One is only oil production. And you will send the oil to other oil refinery companies. Basically, you can start this type of unit with moderate capital investment.
 
Another way you can start the unit along with a refinery setup. However, this type of unit operates as a large-scale and demands substantial capital investment.

Soybean Oil Extraction Process by Solvent Extraction

 
The first step is cleaning the soy seeds. Then, dry the seeds and dehull prior to oil extraction. You have to remove the soybean hulls because they absorb oil and give a lower yield.
 
However, you can dehull by cracking the soybeans. Finally, separate the hulls and cracked soybeans mechanically. Additionally, you can use magnets to separate any iron particles from the soybeans.
 
The soybeans are also heated to about 75°C to coagulate the soy proteins to make the oil extraction easier. For extracting the oil cut the soybeans in flakes. Put them in a percolation extractor and immerse with a solvent, normally hexane.
 
Counterflow is used as an extraction system because it gives the highest yield. After removing the hexane, the extracted flakes only contain about 1% of soybean oil and is used as a livestock meal or to produce food products such as soy protein.
 
Finally, separate the hexane from the soybean oil in evaporators. And recover the evaporated hexane and return to the extraction process. Now, the hexane free crude soybean oil is ready to go to the refineries.
