The mixing device, made entirely of stainless steel, comprising a longitudinal shaft 1 connected to a rotational drive element; where at least one elongated impeller or blade 5, with rounded edges, is attached adjacent to the opposite end, leaving the free end of the shaft extending beyond the impeller 3. The free end of the shaft forms a loop 2 and the blade is mounted across the loop to leave a spacing element below the blade 3. The addition of this loop enhances the structural rigidity of the connection between the shaft and the blade. The impeller 5 has a plurality of tapered apertures 6 along its length that extend through the impeller 5 and are tapered on opposing sides of the impeller. When the mixing device is placed in a container 15 and rotated it forces the liquid 10 through the tapered apertures 6 increasing the fluids velocity, including drag forces F1 around the blade and inducing circulating forces F1 and F2 which produce a cyclone effect 8. |
