Abstract

Multi-stage stirred reactor having reduced back mixing The present invention relates to a multistage stirred reactor, comprising a multiplicity of mutually adjacent reaction chambers and stirring elements for mixing the contents of at least one of the 5 reaction chambers, wherein, between adjacent reaction chambers, there is in each case provided at least one opening that can be closed by means of closure means, such that in the open state there is a fluidic connection between the adjacent reaction chambers and in the closed state the adjacent reaction chambers are separated from one another. At least one of the closure means (300, 310, 320) is connected to an actuation rod (500, 510, 520) that is guided out of the stirred reactor. The 10 actuation rod (500, 510, 520) can be moved back and forth between at least one first position and a second position, by rotation and/or displacement, wherein in the first position closure means (300, 310, 320) that are connected to the actuation rod (500, 510, 520) effect an open state of the opening assigned to them and in the second position closure means (300, 310, 320) that are connected to the actuation rod (500, 510, 520) effect a closed state of the opening assigned to them. 15 FIG. 1
