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.

Abstract: An agitator for mixing food or other materials in a kettle either with or without heating of the materials, the invention allows gentle and thorough mixing of materials ranging from liquids to semi-solids. The present agitator is especially usefual, for mixing and blending of substantially liquid mixtures having suspended solids, the solids being uniformly suspended within the mixture without damage to the solids. The agitator preferably takes the form of a rotary shaft horizontally disposed within a kettle having a substantially hemispherical bottom portion, each end of the shaft having a substantially arcuate element of particular contour attached thereto. The arcuate elements lie in planes which are perpendicular to each other and are the same general shape.

Abstract: A sanitary seal assembly useful for sealing a rotary through-wall shaft in both static and rotary modes, the invention provides a sealing structure capable of being fitted to external wall surfaces of a cooking kettle or the like for rapid manual assembly and disassembly for cleaning according to sanitation standards. The sealing assembly includes a seal retainer having static and rotary sealing elements, the seal retainer being held in place by compression forces exerted by a pivotable seal compression element. The seal compression element is pivotable at one end to release pressure on the seal retainer to allow removal of the retainer for cleaning of the seal assembly.

Abstract: A mixing agitator for use in a kettle wherein food is mixed either with or without cooking of the food, the invention allows gentle mixing of substantially liquid mixtures to suspend solids uniformly therein without damage to the solids. The agitator preferably takes the form of a rotary shaft horizontally disposed within a kettle having a substantially hemispherical bottom portion, the shaft having contoured blade-like elements attached thereto which act on rotation of the shaft to lift material from the bottom of the kettle to the top of the body of the food and thus produce a uniform dispersion of liquid and solid materials during a cooking/mixing processing phase, a mixing only phase, or a subsequent phase of dispensing the uniformly mixed material from the kettle.
