Nauta Dryer: Efficient Conical Mixing Technology

S2 Nauta Dryers are expertly designed to optimise efficiency in drying processes through innovative conical mixing technology. These advanced systems feature a primary mixing screw inclined at the same angle as the cone wall, which ensures effective conveyance of the product from the bottom of the vessel to the surface. The mixing screw is mounted on an arm connected to a central drive mechanism, allowing it to orbit the vessel's inner circumference, thoroughly mixing the process media and facilitating heat transfer through convection.
