An ideal mixer for creams, ointments, pastes, liquids, and wetted powders. The sturdily constructed planetary gear can be equipped with various mixing and kneading attachments, made of stainless steel each of which is easily interchangeable. Depending upon the type of material to be processed, a dough arm, a mixing paddle, or a wire whip can be supplied at an extra cost. Any material, which sticks to the walls of the kettle, is scraped continuously by the Teflon scrapper, which is shaped to fit exactly the kettle wall. Therefore, homogeneous mixing results in the shortest time can be achieved. The planetary mixer is suitable for screwing on all main motor drives.
