For processors who seek the benefits of both continuous gravimetric blending and control of extruder output by weight, we offer a solution that combines both technologies in one integrated, easy-to-use system. The operator enters the desired blend percentages and desired extruder rate into the operator station. The blender's computer accurately maintains the desired ingredient blend percentages by weight. Simultaneously, the blender computer calculates the actual extruder usage rate and periodically adjusts the extruder screw speed to maintain extruder output to +/-.5% by weight. The blender computer can also control line speed for consistent weight per length of product. This feature can be easily retrofitted in the field for both mono-and coextrusion applications.
