Abstract: A mixer comprising a shaft which is appropriately curved to substantially conform to the interior shape of the sides and bottom walls of a steam kettle and a structure for supporting the shaft within the steam kettle. The latter consists of a lid which fits about the peripheral upper edge of the steam kettle. A length of a heat resistant, self lubricating, tubular material, such as Teflon, is slidably extended over substantially the entire length of the shaft, to perform a dual function. This material, first of all, eliminates the need for any type of bearing structure which normally would be required in order for the shaft to be rotated when disposed to extend through the lid, into the steam kettle. The material itself functions as a bearing. Secondly, the material being heat resistant can seat on the bottom of the steam kettle and thereby permit the shaft to be easily and properly seated in the steam kettle without the need for other mechanical devices.
