Abstract:
A method of mixing a fluid comprising the steps of:isolating a fluid to be mixed in a container;providing a mixing structure having a support having a top side, a bottom side, an outer edge and an axis of rotation passing there through generally perpendicular to said top and bottom side, a number of vanes spaced about the periphery of said support, each vane having a first end connected to said support and a second end positioned remote from said support, said vanes extending from at least one of said sides of said support generally parallel to said axis, said vanes having an outer edge and an inner edge, said outer edge positioned near the periphery of said support, said vanes extending inwardly towards a center of said support to said inner edge, said vanes having a maximum spacing therebetween of less than about 0.45 inches and having a length between said first and second ends thereof in a ratio of vane length to a maximum dimension of said support of no more than about 0.3;positioning said structure in said container containing fluid; androtating said structure within said container containing fluid about said axis, whereby said fluid is mixed and undispersable materials are strained by said vanes.
