GROSSVOLUMIGER REAKTOR BEZIEHUNGSWEISE DÜNNSCHICHTVERDAMPFER MIT EINEM VORMISCHAGGREGAT

Thin film evaporator /reactor comprises a horizontal cylindrical containment shell (12), at least one top vapour outlet and bottom liquid outlet, and a feed inlet opening (22) incorporated in a pre-mixing assembly (30) attached directly to the main shell. The reactor has a horizontal axial multiple lobe scraper rotor (78). Independent claims are included for processing in a thin film reactor/ evaporator materials which are charged via a pre-mixing assembly connected directly to the main shell. The pre-mixing agitator system comprises a labyrinth type arrangement of two or more cylindrical stator baffles (42, 46, 50) and an impeller (44) with one or more circular arrangements of up-standing pins, which are rotated between the baffles via a drive shaft (56). A pre-mixer comprising an arrangement of horizontal impeller blades on a vertical drive shaft intersecting with stator baffles is claimed. The pre-mix agitator (44) typically rotates at 10-20x10 3> rpm; the reactor/evaporator rotor (78) operates with a tip speed of approximately 20-60 m/s.
