Question

Different type and size of extractors for soybean oil extraction

Answer 1

There are two methods of soybean oil production, one is mechanical way, which is a traditional method that use screw press machine to squeeze oil out from seeds and kernels; the other way is chemical method that extract oil with solvents. Both two oil production methods have advantages and disadvantages. The previous one is natural and healthy but the oil yield is much lower, however, oil yield of the solvent extraction method is much more higher. You can choose one according to the capacity and your oil making needs, or you can use the two together.

To produce soybean oil, the soybeans are cracked, adjusted for moisture content, heated to between 60 and 88 ºC (140–190 °F), rolled into flakes, and solvent-extracted with hexanes. The oil is then refined, blended for different applications, and sometimes hydrogenated.
