ABSTRACT:
To minimize an amount of unmixed fluids remaining inside, the mixing element includes right-handed and left-handed spiral blades (1) having a shape twisted 180 degrees and being alternately and continuously provided in the axial direction to make end parts (1a) of the adjacent spiral blades to orthogonally cross, turbulence generating parts (1c) divided by an extension face (1ca) ad a rising face (1cb) are formed at four portions, which continue toward a front-side side edge (1aL1) and an outer periphery at a part spirally continuing to the back side from the front-side side edge (1aL1) and are surrounded by a front-side end edge (1cL1), an axial-side edge (1cL2) and a front-side edge (1cR1), and an inflow part (1d) formed by notching a portion from an end-part starting edge to a back-side end edge is formed at a back-side side edge opposed to positions of the turbulence generating part (1c).
