HB Reactor

The HB Reactor is a horizontal twin-shaft reacting processor.
This product was added to our lineup in 2015 and was developed based on the construction principles of our proven KRC Kneader.

Both ends of the shafts are held by bearings, so that the counterpart paddles, or the paddles and the barrel wall never make contact. Special paddles and the gear pump installed at the outlet ensure a long residence time of the materials inside of the barrel. Through this, the HB Reactor is suitable for any complex reaction processes that require a residence time of more than 10 minutes. The paddles are modular, so that the paddle pattern can be adjusted according to the intended application.

Another feature is the barrel shape, which is larger in volume than that of the KRC Kneader. This shape further enhances the reaction-promoting effect by increasing the available reaction space. The simultaneous dynamic change of the reactive surface by the rotating paddles intensifies the surface renewal effect of the materials inside the barrel in addition.

The barrel can be operated under vacuum condition up to 133 Pa absolute. Furthermore, the barrel is available for high temperatures up to 350℃.

In the plastics industry, the HB Reactor is especially used for polycondensation (e.g. polyamide, LCP, PET), solution polymerization (e.g. super absorbent polymer), emulsion polymerization (e.g. PLA) and monomer extraction and devolatilization (e.g. POM, special olefin series materials).
