The Continuator bridges the gap between short residence time paddle dryers and long residence time disc or rotary dryers. An indirectly heated vessel and slow speed rotor keep materials in a heated, agitated state for precise control of drying or thermal reaction. Used in a variety of operations, including mixing, drying, reacting, and devolatilization. Able to operate in either batch or continuous mode, the Continuator is outfitted with either a ribbon-style rotor for homogenizing and blending, or a paddle style rotor for a more plug-flow type operation. The Continuator dryer is best suited for pre- or post-thermal treatment, or in batch operations for long reactions.
