A filter for separation of a liquid from a solid has a turbine surrounded by an elongated filter body and forms a short first stage with short-pitch blades, providing a high axial impulse and low radial impulse, followed by a long second stage with long-pitch blades providing primarily radial displacement. Water vapor can be injected to promote juice extraction and is fed axially into the shaft and emerges from outlets therealong.
