Kneader reactor is developed from kneader mixer to process high viscosity materials. It is a horizontal, closed type continuous/batch kneading/reacting processor. Compared to twin screw extruder, kneader reactor has compact structure such as short L/D and low power while having equivalent kneading and dispersion performance and contributing to rationalization of manufacturing process and cost reduction. If required longer residence time and higher production capacity, continuous reactor, plug-flow is available.


  • Excellent mixing and kneading performance during wet, pasty and viscous phases;
  • Large working volume reactors efficiently handling large product volumes;
  • Compact design maximizing process yield per performance volume and minimizing space
  • requirement;
  • Large heat-exchange surface areas yielding highest possible surface-to-volume ratio;
  • Narrow residence-time distribution for plug flow operation;
  • Adaptive for a wide range
  • of residence times;
  • Closed design for cleaner
  • production environment;
  • Robust design for high
  • viscosity processing
  • Maximum self-cleaning;
