The "Nauta" mixer is constructed in the form of an inverted cone with a mixing screw inside rotating around the inside wall. The mixer is made in a variety of sizes. It is excellent for premixing trace elements and works very well for adding moderate amounts of liquids into dry ingredients. Also it is excellent design alternatives for product applications that are shear sensitive, voluminous and also where space on the plant floor is at a minimum.

Nauta mixers are widely used for mixing dry materials, paste, cream and lotions. The principle of blending is based on the differential travel speeds of product particles in the conical section of the vessel. The material from the bottom section of vessel is lifted by the screw and spread over the upper sections.
