[0037] During operation: The motor drives the rotating shaft and rotor to rotate, and the rotor needles installed on the rotor also rotate synchronously. The stator ring is in a fixed state, and the stator ring needles installed on the stator ring are also in a fixed state. During rotation, each rotor needle passes through the space between two stator ring needles to ensure that the rotor needle does not collide with the stator ring needles during rotation, thus smoothly emulsifying the material. In order to adapt to the emulsification requirements of different materials, it is necessary to replace different types of rotor needles and stator needles. Simply remove the rotor and stator ring, install the new rotor needle in the rotor slot of the rotor, and install the new stator ring needle in the stator ring slot of the stator ring. After reinstallation, it can be used. It is easy to disassemble and use, highly versatile, and has a good emulsification effect.

[0038] It's worth noting that when emulsifying different materials, if changing the motor module's speed fails to achieve the required emulsion fineness, the rotor and stator ring can be disassembled.

Referencing the design manual can help find the optimal combination. The stirring needles in the rotor and stator ring assemblies can have 2, 3, 4, or 5 different shapes.

Different stirring needles have various functions, such as those specifically designed for cutting colloids, solid-liquid mixtures, liquids, or biological cells. The materials can be general-purpose or specialized, including but not limited to colloidal mixtures, solid-liquid mixtures, liquid-liquid mixtures, and gas-liquid mixtures.
