FAQ about vegetable oil processing technology

There are two methods for making soybean oil. One is a mechanical method, which is a traditional method, using a soybean oil presser to press oil from seeds, and the other method is a chemical method to extract soybean oil with a solvent. This method is also called soybean oil solvent extraction process.

Mechanical way of soybean oil extraction -------Soybean oil press machine

Soybean oil pressing method is more suitable for small-scale soybean oil extraction production line. If your processing capacity is under 10 tons per day, you can equip a screw press without the pretreatment machine. If your capacity is between 10 tons per day and 20 tons per day, we recommend that you build a small scale soybean oil press production line, including pretreatment equipment, oil press machine and filter. The pretreatment equipment can be equipped with magnetic drum, cleaning sieve, destoner, flaking machine, cooker, etc. according to your needs. The oil extracted by pressing method is naturally and healthy. But the residual oil rate is around 7%-8%.

Chemical way of soybean oil extraction -------Soybean oil solvent extraction plant

The soybean oil solvent extraction production line is suitable for soybean oil extraction plants with large capacity. If your processing capacity is above 30 tons per day, the soybean oil solvent extraction production line is your best choice. Extracting soybean oil by solvent extraction method, the residual oil rate of the cake is less than 1%, and the production is more energy efficient. But soybean must be pretreated before solvent extracting. Solvent extraction pretreatment includes cleaning, crushing, softening, flaking, puffing and drying
