The ribbon mixer is driven by the inner and outer diameter spirals installed on the stirring shaft to drive the material in the barel so that the stirrer can turn the animal material in the maximumrange of the barrel.

The structure of the stirrer, the spiral design is inside and outside, and the left and right are anti-spiral. When the stirrer is working, the spiral drives the material near the axis to do the axis rotation, the axial direction is pushed from the inside to the sides, and the outer spiral drives the material near the barrel well. The axis rotates, and the axial direction is pushed from both sides to the inside, thus cusing the material to convectively circulatem shear and infiltrate in the barrel, and complete the rapid and uniform of the materials in a short time.
