Abstract
Official abstract text for this publication.
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 t steady,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 t steady,2 .
First claim
Opening claim text (preview).
What is claimed is: 1. A mixing device for mixing components, comprising: a mixing vessel being adapted to accommodate the components to be mixed; a rotatable shaft with at least one mixing impeller mounted thereon, the rotatable shaft and the at least one mixing impeller being arranged inside of the mixing vessel and being configured to mix the components when being rotated; a drive unit for driving the rotatable shaft and the at least one mixing impeller mounted thereon; at least one sensor provided at the rotatable shaft or at the at least one mixing impeller for detecting a decrease in torque; and a controller configured to change a rotational speed or a rotational direction of the rotatable shaft when the at least one sensor detects a specified decrease in torque that is indicative of a vortex in the components being mixed. 2. The mixing device of claim 1 , wherein the controller is configured to: accelerate 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; rotate the mixing impeller at the first desired speed for a first time t steady,1 in the first rotation direction; change the rotation direction of the mixing impeller, so that the mixing impeller rotates in a second rotation direction at a second desired speed; and rotate the mixing impeller at the second desired speed for a second time t steady,2 . 3. The mixing device of claim 2 , wherein the mixing vessel is a single-use container.
