Abstract

A stirring unit has a number of stirring blades (14) where each has a section (20) bent forwards in the direction of rotation, at the trailing end of the blade and in a radially outer zone. The ratio of the radial length (L1) of the bent section to the total radial length (L2) of the stirring blade is 0.2-1.0 and preferably 0.4-0.6. The ratio of the width (B1) of the bent section to the total width (B2) of the stirring blade is 0.1-1.0 and preferably 0.15-0.4.
