  • Patent number: 9302231
    Abstract: A seed treating device that has an input device that is detachably secured to a frame. Disposed within the frame is a mixing chamber that receives seed from the input and is in fluid communication with a pump. In this manner the pump is able to convey chemical treatments to the interior of the mixing chamber such that a blade assembly within the mixing chamber can mix the chemical treatment fluid with seeds therein in order to treat the seeds with the chemical treatment.

  • Patent number: 7771111
    Abstract: A liquid phase continuous reactor which includes a screw rotatably disposed within a barrel and defining a mixing zone therebetween whereby the relative rotation of the screw with respect to the barrel is adapted to axially transport materials disposed between the screw and the barrel while mixing the components wherein the land surface area between the spiral groove forms at least 50% of the surface area of the screw in a mixing zone.

  • Patent number: 7600911
    Abstract: A static mixer tank includes upper/first and lower/second mixing chambers, with the two mixing chambers being separated by a swirl chamber. The upper mixing chamber is arranged at an upper end of the mixing tube where materials would initial begin passage there through, and the lower mixing chamber is arranged at a lower end of the mixing tube and receives materials that may have to some degree been mixed by their passage through the upper mixing chamber. A series of baffles in the mixing chamber are arranged in sinusoidal or saw-tooth pairs that can be oppositely arranged, so that the mixer turns a drop of water into hundreds of micro-bubbles of rotating fluid, which allows the chemicals to exit the mixer and react with fluid in a storage tank as much five times faster than previously known. A variation includes a sand trap using the swirl chamber, cap, diverter chamber, and diffusing plate to separate sediment from a liquid without using a filter of moving parts.

  • Patent number: 6719448
    Abstract: Material processing apparatus (10) is provided for the simultaneous production of different characterized final products using a single, initially processed product stream. The apparatus (10) includes a barrel assembly (12) having an elongated, tubular barrel (16) with a flighted, axially rotatable screw (26) within the barrel, and an additive incorporation assembly (14) coupled with the barrel (16) and having a plurality of individual mixing chambers (34, 36) configured to receive and process individual, separate streams of product from the barrel assembly (12). Individual additive injectors (52, 54) are also provided for injection of additives such as colorants or the like into the respective product streams for mixing with the chambers (34, 36). Preferably, the assembly (14) includes a flow divider (32) having plural separate passageways (46, 48), which are in communication with the corresponding mixing chambers (34, 36).
