Description

[0003] At present, a mixer is generally used to process fillings in production. Different fillings are pre-placed in the mixer, and then stirred by the mixer to achieve mixing of different fillings.

[0004] When mixing fillings, the current mixer is prone to insufficient mixing uniformity due to its relatively simple stirring structure. At the same time, since the fillings themselves are sticky, they are easily attached to the side walls of the mixer under the drive of the single stirring structure, which not only affects the mixing uniformity but also makes the cleaning of the mixer more difficult.
