Aerating blender

A mixer apparatus configured to mix the contents of an associated vessel, the mixer apparatus comprising:

• a rotational mechanism;
• a gearbox attached to the rotational mechanism;
• first and second shafts respectively attached to the gearbox with the gearbox configured to rotate the first and second shafts in respective opposite directions, and with the first and second shafts coaxial to each other and with the first shaft located at least partially inside said second shaft to form paired inner and outer shafts;
• a first rotor, comprising a plurality of first rotor blades, and configured to be rotated by the first shaft;
• a second rotor, comprising a plurality of second rotor blades, and configured to be rotated by the second shaft;
• a housing enclosing the gearbox adjacent a proximal end of the housing and having a distal end extending towards the first and second rotors;
• a plurality of fluid entry openings formed in the periphery of the housing and adjacent the gearbox;
• a plurality of fluid exit openings formed in the periphery of the housing and adjacent the rotors;
• and
• at least a pair of fluid impellers, attached to the outer of the two coaxial shafts, for rotation within the housing as the outer shaft is rotated, and located adjacent the plurality of fluid entry openings so that as the impellers are rotated, fluid is drawn into the housing through at least one of the fluid entry openings, and pushed along the interior of the housing and out at least one of the fluid exit openings as aerated fluid.

Methodology for a mixer configured to mix the contents of an associated vessel, the methodology comprising:

• providing a rotational mechanism;
• providing at least one shaft configured for rotation by the rotational mechanism;
• providing at least one rotor with at least one rotor blade, with the rotor arranged to be driven by the at least one shaft;
• providing a housing enclosing a region adjacent a proximal end of the housing and having a distal end extending towards the at least one rotor;
• providing the housing with at least one entry opening for air to be drawn into the housing, and with at least one exit opening for aerated air to exit the housing;
• and
• controllably rotating the at least one shaft so that air is drawn into the housing through the at least one entry opening and aerated air is pushed out the at least one exit opening.
