The first rotation speed is greater than the second rotation speed and in the opposite direction.

8. A blending method of the blending device according to any one of claims 1 to 7, comprising the following steps: In the first step (S1), the first fluid enters the blending container from the input interface via the delivery channel, and the second fluid enters the blending container via the infusion port. In the second step (S2), the stirring device driven by the first driving unit rotates at a first rotation speed, and the filtering device driven by the second driving unit rotates at a second rotation speed different from the first rotation speed to form a predetermined vortex in the fluid in the container shell, In the third step (S3), the blended and filtered fluid is discharged from the output port.
