Sensor improves the quality of vacuum extruders – automatic control of fill level and entire shaping systems
Until now, front-to-back control of vacuum extruders was unachievable, because it was not possible to monitor the exact fill level of the de-airing chamber. True enough, a limit switch kept the de-airing chamber from closing if the auger was overloaded, but there was no way to detect underfilling. The consequence: inferior quality due to inferior production conditions. Moreover, extruding augers yield unbalanced results, if the fill level fluctuates.
