1. A mixing system, comprising
a container;
an interior mixing element in the container; and
a mixing device comprising a rigid exterior shaft having a first end section defining a first axis and a second end section defining a second axis aligned to the first end section at an acute angle, the first end section being mounted to an exterior drive that rotates the first end section about the first axis, the second end section being rotatably mounted in an exterior bearing fixed to a wall of the container, an interior shaft having a first end section rotatably mounted in an interior bearing fixed to the wall of the container and aligned at an acute angle to the first axis of the exterior shaft, the interior shaft further having a second end section aligned at an acute angle to the first and section of the interior shaft, the interior mixing element being fixed to the second end section of the interior shaft, wherein the exterior drive rotates the first end section of the exterior shaft about the axis thereof and generates a nutating motion of the interior and exterior bearings, and wherein the nutating motion of the interior bearing causes a rotating motion of the second end of the interior shaft and the mixing element mounted thereto about the axis of the second end section of the interior shaft.
