S1KRC Kneader S1KRC Reactor


We have developed an Ultra-compact Kneading and Reacting Unit, which is the best suited for the research and development of continuous reaction.
This unit makes it possible to collect a large number of samples and data using a bit of samples, and pursue the research and development in a short period.


  • Compact design requires the floor space only of 1.5 m2or less.
  • Excellent self-cleaning action
  • A bit of sample (e.g. effective capacity of 120 cc) makes the unit operational.
  • Powerful mixing
  • Available for high-viscosity materials
  • Enhanced piston flow of process materials
  • Respondent to all phase changes


1. Kneader

  • Blending and mixing of broad materials

2. Reactor

  • Polycondensation reaction and mass polymerization reaction of polymers
  • Removal of monomers and unreacted materials
  • Desolvent
  • Drying and evaporation
  • Solidification
