  • Patent number: 8017090
    Abstract: Phosphine gas is generated by agitating a reaction mixture of a metal phosphide and water with agitation air in a reaction pot of a phosphine gas generator. The resulting phosphine gas is then diluted with dilution air to produce a fumigant phosphine gas which is directly delivered to a commodity for fumigation. The reaction pot does not have any rotating means such as agitators, rotors, or stirrers. The generator provides on-site generation of phosphine gas in a rapid manner improving the fumigation efficiency for a commodity, such as grain, preferably contained within a storage structures, such as a grain silo. The generator has a built in deactivation system for the unused metal phosphide and phosphine gas.

  • Patent number: 7473685
    Abstract: Dry flow, low compact, dust free, soluble granules of phosphoroamidothioates, preferably acephate, are produced by the process of 1) pre-mixing technical grade phosphoroamidothioate with specified adjuvants and other inert ingredients; 2) grinding to produce a ground product having a preferred particle size of 5 microns to 10 microns; 3) post-mixing; 4) granulating; 5) drying; 6) sizing to required length, preferably 1.5 to 3.0 mm; 7) and sieving to remove the fines to get the desired dust free soluble granule.

  • Patent number: 6752943
    Abstract: Uniformly sized granules are formed using the present extruder and granulation process. The extruder contains a spiral worm screw for guiding a granulation material to an apertured plate. The spiral worm screw is rotated within a chamber and is formed from a guiding slant which terminates at a blunt edge near the apertured plate. The blunt edge rubs the granulation material against the apertured plate which softens the material foming a semi-solid material. The semi-solid material is then gently pushed through the apertured plate using just the required pressure. The granules are formed when the semi-solid material hardens after exiting the apertured plate.
