  • Preparation of guar suspension from guar splits
    Patent number: 7790774
    Abstract: A continuous process forms liquid or semi-solid suspensions of water-hydratable guar particles in a non-aqueous solvent directly from hydrated guar splits. In particular, guar splits are hydrated, compressed to form wet guar flakes, and then dried. The dried guar flakes are then combined with a non-aqueous carrier fluid. Finally, the guar and carrier fluid mixture is homogenized, and, if desired, the homogenized guar and carrier fluid mixture may be shear milled to further size-reduce the average particle size of the guar particle.
