The device has a promotion piston (20) that is provided for driving specific component (16) from inner space to outside. A hollow portion (12) is provided with promotion piston which is reached into screw thread (18) of hollow portion. A propulsion element (24) is arranged within housing (2) to convert flow of main component into a rotating movement. The promotion piston is screwed into inner space of hollow portion by rotating movement of propulsion element, such that specific component is pressed from cavity into fluid stream of main component. An independent claim is included for a method for manufacturing multi-component mixture.
