  • STIRRER WITH DETACHABLE PARTS
    Publication number: 20250235835
    Abstract: This application discloses a stirrer with a direct drive motor comprising a stator module with a rod mounted onto a stator and a rotor module comprising a rotor encapsulated in a housing and connected to an impeller. In some embodiments the rod functions as a cooling device to prevent the stator from being overheated during stirring. The stator module and the rotor are encapsulated in their separate housing and are detachable from each other and the impeller to allow the user to clean, disinfect, maintain or repair the stator module, rotor, impeller, and coupling between the stator module and the rotor before further use. Depending on the type of impeller added, it may be used for moving, stirring, mixing, agitating, blending, aerating, homogenizing, or cutting the medium.
