A method and apparatus are disclosed for extracting finished juice from an initial juice including substantial solids or for extracting fluid, preferably finished to a high degree, from any slurry including substantial solids, wherein the slurry is introduced into one end of a cylindrical screen, the cylindrical screen being driven in rotation for centrifugally urging the slurry against the screen and causing fluid from the slurry to pass through the screen. Paddles are arranged for rotation with the screen and for limited movement relative to the screen for continuously spreading the slurry along the screen to facilitate separation of fluid and for moving solid material from the slurry toward an outlet end of the screen for removal, the paddles preferably being mounted on a support drum forming an annular passage adjacent the screen for receiving the slurry, the support drum preferably being driven by differential means adapted for adjusting the relative rates of rotation for the screen and support drum to selectively regulate the amount of movement of the paddles relative to the screen. |
