Artisan introduces a new option to its Rototherm thin-film evaporators and dryers. By incorporating a special screw device directly into the unit, the potential for product build-up in the outlet is eliminated. This is especially effective for materials that become sticky, viscous, tarry, and/or crust-forming as they are concentrated or dried. A screw barrel is integrated into the evaporator, in place of a conventional outlet nozzle. The barrel is oriented perpendicular to the axis of the Rototherm and placed such that the screw is tangent to the rotor blades. A single screw or self-cleaning, intermeshing twin screw is installed in the barrel.
