The small traditional Chinese medicine mixer part is a single-shaft single paddle. The angle design of the paddle on the single paddle is very reasonable and ingenious. When the single paddle rotates, the material rolls up and down, and at the same time, the paddle passes through the material and pushes to the left and right sides of the mixing tank at a certain angle. The force makes it impossible for the material in any corner of the mixing tank to stand still, so that the material can be mixed evenly. This machine adopts the sealing method of end face sealing, adjusting the sealing nut and compensating the axial pressure. Practice has proved that the effect is better. The whole machine is sealed with stainless steel, which meets the requirements of GMP.
