A new system was developed to mix viscoelastic fluid. To prevent fluid from creeping up the impeller shaft by the Weissenberg effect, the impeller was stopped, and the vessel was rotated, with periodic reversal of the direction of rotation. The impeller used was an anchor type that scraped the fluid from near the vessel wall. Viscoelastic fluid with the very large apparent viscosity of silicone rubber could be mixed efficiently with this system. © 2015 The Society of Chemical Engineers, Japan.

[Object] There are limitations on the mixing efficiency for chemicals with one rotor. [Solving Means] A housing 1 which has a discharge nozzle 7 in its lower portion, one driving rotor 3 which is disposed in a space portion 2 in the housing 1, and driven rotors 4 and 4 which are installed side by side with the driving rotor 3 are provided, and a through hole 5 for a drive shaft S of a head part is formed in the upper portion of the housing 1, the upper end of the driving rotor 3 is coupled to the lower end of the drive shaft S, and inlets 6 and 6a for chemicals to the space portion 2 are formed in the upper lateral side of the housing 1, thereby it is possible to stir and mix a mixed liquid with the plurality of rotors 3, 4, and 4.
