The 42NSD ribbon blender features a discharge screw positioned across the entire bottom of the trough and powered by a separate direct drive system for independent speed control. The discharge screw assembly is designed with close tolerances between the screw and the trough. The screw runs forward only during the discharge cycle and in reverse during the blending cycle. This helps to eliminate dead zones and enhance mixing. The 10-cu-ft unit shown included all stainless steel type 316 construction, a 150-grit finish on all surfaces, a dust-tight, two-piece cover with clamps, liquid spray nozzles, a 3-in.-diam discharge screw, load cells, and a NEMA 12 stainless steel control panel. Advantages of this design include: the ability to discharge continuously at variable rates to match downstream packaging operations; a removable screw for cleaning purposes; less dead space, thus more thorough blending; complete discharge.
