ABSTRACT:
An arrangement for mounting scraper elements to portions of a mixing agitator such as an agitator intended to mix foods or other materials in a kettle either with or without heating of the materials, the mounting arrangement holds the scraper elements in scraping relation to interior walls of the kettle and biases the scraper elements against the kettle walls so that materials being mixed in the kettle are prevented from adhering to interior surfaces of the kettle. The mounting arrangement includes structure integral with the scraper element as well as structure mounted directly to the agitator and connecting to the scraper element for holding the scraper element in a desired location relative to the agitator and thus relative to the kettle walls. Further, the mounting arrangement includes a spring structure for resiliently biasing the scraper element against the kettle walls so that scraping contact is maintained on rotation of the agitator within the kettle. The mounting arrangement of the invention can be used with agitator devices of widely varying structure and varying rotational orientation within a kettle.
