Soybean Oil Solvent Extraction Process
Soybeans have a relatively low oil content (15-22%). To obtain more oil and considerable economic benefits, soybean extraction is generally used to produce soybean oil. The extraction method mainly uses solvent oil (hexane) to fully soak the treated soybean, so that the oil in the soybean is extracted. After extraction, the residual oil in the cake is generally less than 1%. Soybean meal cakes can also be used to process animal feed.

Soybean Extruding Process
Soybean extruding is the process of using extrusion equipment to break through the crushed, rolled soybean into porous, expanded granular material. Extrusion is a kind of high-temperature and short-time processing. At present, the commonly used soybean extruding machine is a moisture single-screw extruder, and the material is extruded by heating, pressing, gluing, and vacuum extrusion. Generally, the extrusion temperature can reach 110~200℃, and the residence time in the extruder is 1~3 minutes.
