Abstract
A mixing method, a controller and a mixing device for mixing components in a mixing vessel are provided. The mixing method includes providing a mixing impeller in the mixing vessel; accelerating the mixing impeller from an inactive state to a rotating state in which the mixing impeller rotates at a first desired speed in a first rotation direction; rotating the mixing impeller at the first desired speed for a first time tsteady,1 in the first rotation direction; changing the rotation direction of the mixing impeller, so that the mixing impeller rotates in a second rotation direction at a second desired speed; and rotating the mixing impeller at the second desired speed for a second time tsteady,2.
