ABSTRACT:
The present invention discloses a mixing kettle which utilizes magnetic force to maintain contact between the scraper blades and the interior surface of the kettle. A series of scraper blades are pivotally mounted within pivot brackets carried on horizontal, anchor type scrape-surface agitators. A first magnet is imbedded within each scraper blade, fabricated from nylon or other similar material, while a second magnet of like polarity is carried within the pivot bracket adjacent the first magnet. The repulsive force between the magnets forces the blade to pivot such that the scraper end of the blade is forced against and rides along the interior of the kettle.
