As the stirrer, a stirrer as a material is mixed and stirred, and a stirrer according to the prior art is disclosed in the prior art document (Korean Patent Laid-Open Publication No. 2009-0022591).

Conventionally, when the rotor 210 and the stator 220 constituting the stirring unit 200 are vertically moved up and down with respect to the container 11, the stirring object 200 is moved up and down in the container 11, And the stirred or agitated object to be stirred is discharged to the outside of the container (11). That is, when the rotor 210 and the stator 220 are lifted and positioned inside the container 11, the object to be stirred is stirred by the rotation of the rotor 210, and the rotor 210 and the stator 220 are lowered and are positioned outside the container 11, the stirring object which has been stirred outside the container 11 is discharged.

However, such a conventional stirrer has the following problems.

In the prior art, the rotor 210 and the stator 220 integrally move up and down. Therefore, in the conventional art, there is a fear that the stirring object remaining in the space between the rotor 210 and the stator 220 may not be discharged to the outside.

Also, conventionally, the rotor 210 and the stator 220 are selectively positioned at a position for stirring and a position for discharging the object to be stirred. Therefore, conventionally, there is a disadvantage that the state of the object to be stirred or the form of the stirring, for example, the mixing and homogenization of the object to be stirred, can not be optimized.
