As described above, in an embodiment in which the twist direction of the bottom surface 427 is opposite to the direction of rotation with respect to the top surface 425, the leading surface 423 of the second blade 420 applies a horizontal force to the material to be stirred. In addition, as the downward force is applied and the twist angle of the second blade 420 increases, the convective movement of the material to be stirred in the vertical direction increases and the horizontal rotation decreases. can

As described above, the second blade 420 has a simple plate-like shape without a central through hole, and enables more efficient stirring by stirring the material to be stirred and simultaneously performing a grinding action. However, depending on the situation and purpose, such as the type of material to be stirred or the user's choice using the mixer, the second blade 420 may have a frame shape with a through hole formed in the center and a body formed only at the rim. In this case, the grinding It may be a design that puts more emphasis on agitation of the substance to be stirred than on the action.

In some embodiments, the first blade 410 and the third blade 430 may be arranged so that the nearest distance between the inner wall of the container 310 is 3 mm to 8 mm. By configuring in this way, the first blade 410 and the third blade 430 not only perform grinding between the second blade 420, but also the material to be stirred based on the inner wall of the container 310. Grinding can be performed to increase the grinding area and the grinding efficiency of the target material.

In some embodiments, the first blade 410, the second blade 420 and the third blade 430 may be arranged so that the nearest distance between the bottom surface of the container 310 is 3mm ~ 8mm.
