This type of equipment mixes materials to form a consistent product. Homogenizers, commonly used in the dairy industry, mix a product by pumping the product through valves and other openings. Homogenizers can be used to break down and evenly distribute fat particles in milk to create a product that is 1%, 2%, or whole milk. Emulsifiers combine materials that are not chemically inclined to bond together. They break up droplets, then mix in an emulsifying agent to keep the product from separating after the mixing is finished.
