  • Patent number: 8322272
    Abstract: An improved screw feeder assembly is provided for interconnection between the outlet of a preconditioner and the inlet of an extruder barrel. The assembly includes an upright housing with a pair of elongated shafts equipped with auger flighting within the housing and driven by means of motor. Preferably, the housing is mechanically coupled to the outlet and inlet with the shafts extending through the preconditioner vessel and downwardly to a point within the inlet and closely adjacent the screw(s) within the extruder barrel; the flighting is provided along the length of the housing, from a point closely adjacent the outlet and into the extruder inlet. This provides a positive conveyance of preconditioned material from the outlet to the inlet. Use of the assembly allows maintenance of superatmospheric pressures and temperatures above 212° F. within the preconditioner, which permits more efficient processing.

  • Publication number: 20120269028
    Abstract: An animal feed mechanism includes a manually operated slide valve interposed between a set of upper agitators and a set of lower screw conveyors. In some examples, two upper agitators are installed within a plastic funnel, and two lower screw conveyors are disposed within a metal auger housing. Each screw conveyor includes an auger driven by its own separate motor. Thus, there are two motors for rotating the two augers. The two motors can be energized individually to selectively rotate either auger or to rotate them concurrently. In some examples, a transmission coupling the two augers to the two agitators conveys power to rotate both agitators regardless of whether either one or both motor driven augers are operating.

  • Patent number: 6979116
    Abstract: The present invention is an apparatus for introducing a dry material into a fluid stream in a way that ensures a predictable, highly accurate and consistent application of the material. The invention applies variable amounts of dry material regardless of whether the fluid stream flow rate is fixed or variable. The dry material is handled in dry bulk form and may be highly soluble or nearly insoluble. The dry bulk material is metered before being mixed into a slurry and injected to the fluid stream in a manner that continuously and automatically adjusts the application rate to compensate for varying fluid flow rates or chemical composition, in order to provide a precise fluid treatment level at all times. The present invention is capable of storing large quantities of the dry process amendment as an integrated and dust-free function of the apparatus.
