<p>The present invention is a method and apparatus for mixing viscous fluids. In one embodiment, the mixing device includes a shaft (22) having an axis. A support (24) is connected to the shaft. A number of vanes (26) are mounted to the support for rotation by the shaft during mixing. The vanes are positioned outwardly of the axis and extend generally parallel thereto. The vanes have a first end, a second end, an outer edge, and an inner edge. The vanes extend from their outer edge to their inner edge in the direction of the axis. In another embodiment, the inner edges of the vanes are positioned closer to the axis at their first ends than their second ends. In accordance with a method of mixing, the mixing device is placed in a container (42) of fluid (44) and rotated about the axis.</p> |
