[0029] Specifically, the first gear 4 and the third gear 8 are engaged with each other, and the second gear 5 and the fourth gear 9 are engaged with each other.
[0030] In the embodiment: by the engagement of first gear 4 and third gear 8, the engagement of second gear 5 and fourth gear 9, the rotation of outer rotating pipe 2 and inner rotating rod 3 at different speeds is controlled.

[0039] In use, the mixing tank 1 is made of a stainless steel tank body, and the outer rotating pipe 2 and the inner rotating rod 3 are arranged at the center of the tank body.

The outer rotating pipe 2 and the inner rotating rod 3 rotate at different speeds through different sizes of the first gear 4 and the second gear 5.
