Abstract:
     A mixing apparatus has at least two mixing levels, one of which is adjacent to the top and the other is adjacent to the bottom of the container. They move respectively at its appropriate speed, generating a single flow pattern in the fluid of the container. It is better if the mixing device in the bottom is an impeller of large diameter, while the mixing device at the top comprises a set of impellers of small diameter, each of which is symmetrically and equally spaced with respect to the perpendicular rotating axis of the impeller below. Each impeller has a convergent flow field starting from itself.
