  • Patent number: 9718006
    Abstract: A multi-zoned screening apparatus is disclosed for separating fiber from a liquid medium during, for example, a grain wet mill or dry grind process. The apparatus can include a housing having a first and second zone and situated adjacent one another along a length of the housing. A cylindrical screen having a plurality of openings is situated lengthwise within the housing to correspond with the first and second zones. A conveyor is situated lengthwise within the screen and includes an elongated shaft having a first and second conveyor section and along a length of the conveyor that corresponds with the first and second zones, respectively. Each conveyor section is configured to move material in a direction along a length of the screen. In one example, the first conveyor section includes vanes and a ribbon flight helically winding about the vanes, and the second conveyor section includes a plurality of paddles.

  • Patent number: 8813973
    Abstract: An apparatus for filtering a material from a medium includes a first housing having a wall with a plurality of openings formed therein, a conveyor disposed in the housing for moving the material therealong, and a conduit line communicating with the interior of the housing for supplying the medium to the apparatus. At least one of the first housing and the conveyor rotate relative to a central axis to direct the medium toward the wall so as to separate the material from the medium. A method for filtering a material from a medium includes supplying the medium to a first housing, spinning the medium within the housing, passing the medium through a wall of the housing to separate the material from the medium, moving the material along the housing, introducing a fluid into the material within the housing, and washing the material using the fluid.
