As for oil extraction machine, that is using oil extraction method and choosing an organic solvent which can dissolve oil, after contacting with pretreated oil–spray or immersion, so that oil can be extracted.

As the boliling point of solvent and oil are different, after evaporation and stripping, the solvent are evaporating and we can get crude oil.
