The invention relates to an agitator for mixing fluids having different viscosities, wherein the agitator (1) is a bionic agitator, comprising a main shaft (4) with a rotational axis (6) and with paddles (20) which are connected to the main shaft (4), wherein the paddles (20) each comprise a paddle shaft (15) with a paddle shaft axis (28), and wherein the paddle shaft axes (28) comprise a first angle (a) to the rotational axis (6), which angle has a value between 20º and 40º, and wherein the paddles (20) with the paddle surfaces (30) are arranged in a second angle (ß) of 90º to each other, and wherein the paddles (20), during operation of the agitator (1), exhibit a first rotation around the main shaft (4) and a second rotation around the respective paddle axes (28). According to the invention, in relation to the rotational axis (6), a radial first distance of the paddle shaft axes (28) to a bottom end (21) of the paddle shafts (15), which paddle end is formed facing away from the main shaft (4), is greater than a second distance of the paddle shaft axes (28) to an upper end of the paddle shafts (15) formed facing the main shaft (4), in relation to the rotational axis (6). |
