Technology Concept & Benefits

LIST KneaderReactor technology fills the gap between thin-film, extrusion, and conventional drying technologies. It combines the mechanical strength of heavy-duty extruders, the large heat exchange surface of thin-film equipment, and the large working volume of rotary disc dryers.

Feature	Benefit
Large heating/cooling surfaces	Uniform and precise temperature control
High-torque mixing and kneading	Efficient mechanical energy input, boosts surface renewal, enhances heat and mass transfer
Multiphase processing from liquid through pasty/sticky to solid phases in a single unit	Simple, versatile process design
Specialized inner geometry can prevent back-mixing	Enabling liquid feed stocks to be processed directly through to a free-flowing solid product, with no recycling of dry material
Large working volumes	Promotes high throughput, enables long residence times
Long residence times	Facilitates slow reactions and diffusion controlled processes
Axial conveying rate is independent of agitator speed	Rotational speed can be adjusted for optimal heat transfer, residence time, and control of attrition
Effective self-cleaning	Maximizes heat transfer and prevents product accumulation
Large free sections	Easy vapor disengagement and low vapor velocities prevent carry-over even under vacuum
Mechanically robust	Safe processing of highly viscous products
Closed, contained design	Allows processing under vacuum and handling of toxic, explosive, or hazardous materials
