How can an oil press that can directly squeeze cottonseed and pepper seeds clear oil?

The existing oil press integrates oil pressing and oil refining, directly presses cottonseed or pepper seeds and then automatically filters them, which is equivalent to directly putting raw materials, and finally comes out with clear edible oil. There are two filters in the oil press, one for filtering oil cake and the other for filtering clear oil. You can buy a separate centrifugal filter for filtering, but that will be more troublesome.
