The oil content of soybeans is about 18%-22%, and its oil content is lower than that of peanuts and sunflower seeds. So in the soybean oil production process, how can we improve the oil yield of soybean oil? Henan Glory will give you advice in terms of raw materials, process flow and equipment.

1. Ensure the quality of raw materials

If we want to improve the oil yield, we need to ensure the quality of soybean raw materials. For the soybeans used to extract oil, it is best to choose the ones with full grains, no mold, and no damage. In this way, on the one hand, the oil yield rate is increased, and on the other hand, soybeans in good condition can make our oil quality higher.

2. Adequate pretreatment of raw materials

First, use vibrating screens, magnetic separators, stone removers and other celaning equipment to remove stones, iron nails and other impurities in the raw materials. The purpose of cleaning is to prevent these impurities from damaging the machine and improve the oil yield. Then, the soybeans are very hard, we use the crusher equipment to turn the soybeans into uniform granules, which is beneficial to the later operation process. The purpose of the cooker is to adjust the temperature and moisture of the raw materials to ensure that the raw materials are in the best state for oil production. Finally, according to the need, we can choose to add a flaking machine to roll the raw materials into thin sheets and increase the contact area. Before the raw material enters the oil press, it is very effective for us to improve the oil yield after going through these sufficient pretreatment process.

3. Choose the appropriate soybean oil production equipment

Soybean oil production equipment is directly related to the oil yield and quality of our crude oil, so we need to choose suitable and high-quality equipment to help us extract soybean oil. Henan Glory Company can provide you with customized solutions according to your requirements. If your capacity is relatively small, you can directly use the screw oil press after pretreatment. This oil press has been updated many times, and the residual oil rate is very low, about 6%. If your capacity is relatively large, you can choose the method of solvent extraction to extract oil. The residual oil rate of our soybean oil solvent extraction equipment can reach 1%, which can extract the oil in soybean to the maximum extent.
