  • Patent number: 7891498
    Abstract: A liftings trough for mounting in an interior space of a rotatable member of a length grading machine is defined by walls that are contoured to provide a maximum clearance between the mounted trough and an inlet opening through which grain flows into the interior space of the rotatable member, while maintaining a maximum capacity of the trough to receive granules in a particular size range, which are lifted by pockets located along an interior surface of the rotatable member, when the grain flows into the interior space of the member and the member rotates about the trough.

  • Patent number: 7875192
    Abstract: A slurry dividing apparatus is configured to divide a main slurry stream into smaller constituent slurry streams, wherein each stream contains a desired proportion of suspended solids. The dividing apparatus includes a main flow channel and a plurality of branch flow channels extending upward from a flow divider that terminates an upper end of the main flow channel. The main slurry stream enters the main flow channel, at an inlet opening thereof, and is decelerated, by an upward extension and expanding cross-section of the main flow channel, before reaching the flow divider and being divided into the smaller constituent slurry streams flowing within the plurality of branch flow channels. Each of the smaller streams flows up and then over a weir, which extends across an upper portion of each of the branch flow channels, and then down into a corresponding discharge flow channel of the apparatus.

  • Patent number: 7862412
    Abstract: The invention provides for a seal assembly for a grain separator. The grain separator may include a housing, a rotatable grain separation cylinder within the housing, the cylinder having an end surface, a grain inlet having an inlet spout extending through the end surface for conveying grain into the cylinder in a feed zone, an auxiliary end piece or seal cone functionally connected to the end surface of the cylinder. The auxiliary end piece may have an annular external surface spaced laterally from the feed zone, and a seal interfacing with the annular external surface, thereby defining a seal zone spaced laterally from the feed zone. Such grain separators have increased capacity compared to separators with traditional seal assemblies.

  • Patent number: 7401746
    Abstract: An improved design for hammermills. The invention contains a centered rotor from which eight rows of hammers pulverize material against cutting plates inside a working chamber. The cutting plates have slots that are angled. The hammers may have a beveled, angled leading edge. Both the angled cutting plate slots and the angled hammer leading edges work to drive the material through the working chamber in a helical fashion, with a preferred travel profile of 450 degrees, but the helix length is adjustable depending on the specific needs. There are no perforated screens in the hammermill, thus the material is placed in an inlet, is urged through the hammermill by the action of the rotating hammers where the material is comminuted and then removed via an exit.

  • Patent number: 7249404
    Abstract: An improved rotor design for hammermills. The invention eliminates the solid rotor shaft and replaces it with a tubular structure comprised of two stub rotor shafts with plate flanges and grooved spacer rings therebetween. End head disks, attached to the plate flanges, and intermediate disks are concentrically positioned with the axis of rotation of the assembly. The intermediate disks are held in alignment by the pilot groove located in the spacer rings. The flanges, stub shafts, spacer rings and intermediate disks are supported and held in proper alignment by tension rod compression. The resulting tubular rotor shaft assembly is less massive, more stiff, less susceptible to vibration, has a reduced bending stress, is less expensive to startup and operate and less expensive and more flexible in terms of component inventory than known solid through-shaft rotors.

  • Patent number: 7029393
    Abstract: A grain separator having an easily replaceable seal. The separator comprises a housing and a rotatable grain separation drum carried by the housing, the drum having an end face with an external annular bearing surface. A drive shaft extends axially into the drum through the end face, and a grain inlet is carried exteriorly of the housing and includes a bearing rotationally supporting an end of the drive shaft. The inlet includes an inlet spout that extends through the end face for conveying grain to the drum. An easily removable and replaceable split seal is carried about the inlet spout and engages the annular bearing surface to seal the drum from the exterior of the inlet spout, and pressure means are provided for applying axial pressure to the split seal to urge the seal against the annular bearing surface. Disclosed also is a method for seal replacement.

  • Patent number: 6941694
    Abstract: A fishing rod holder with a strike sensor that alerts the operator that a fish has been caught. The fishing rod holder allows for horizontal striking of fish either while trolling or still-fishing. The fishing rod holder consists of a rod holder support arm assembly, a rotating unit, a base unit and an optional mounting adapter. The rod holder may be mounted for horizontal striking on the top surface of a gunnel wall on a boat or other substantially flat horizontal surface. Alternatively, the mounting adapter may be used to mount the rod holder to a boat handle rail. The rod holder support arms are slidably engaged in the support arm assembly and allow for customized vertical orientation of the rod's tip with respect to the reel. In addition, the horizontal orientation of the rod may be customized to accommodate fishing technique and fishing conditions. Finally, there is a strike sensor to alert the operator that a fish has been caught.

  • Patent number: 6938357
    Abstract: An improved centrifugal pellet dryer that employs forced air in the direction opposite that of the pellet travel through the dryer. The air may be preheated depending on the particular product. The resulting airstream reduces water spray and lowers the humidity level of the air in the dryer system. The airstream exits the dryer at or below the lower level of the rotor, thus providing increased exposure to the airflow. The result is enhanced drying effectiveness and increased dryer capacity.
