(3) The kneader-mixer (figure 2-9). The kneader-mixer serves two
functions. It is equipped with a stirrer for use with liquids to be mixed and a kneading
wood roller attachment with which heavy viscosity materials can be kneaded. The unit
is also supplied with a scraper that removes material from the kettle walls and returns it
to the center of the container to ensure proper mixing. The stainless steel kettle rotates
and the mixing attachments move along the inside of the kettle at the same time. A
stirring beater attachment is used to intermix-lighter viscosity materials.
