Apparatus for producing a homogeneous, chemically reactive system

Claim 1

Apparatus for producing a homogeneous chemically reactive system of a starting material of highly viscous or pasty consistency and at least one further reaction partner by forming a thin layer of the starting material and reaction partner comprising: at least one closed substantially vertically oriented vessel having a cylindrical interior side wall and a frontal face at the top of the vessel; at least one inlet opening for the starting material to be treated and at least one inlet opening for each of the other reaction partners, said inlet openings being disposed in the frontal face of the vessel and arranged in close juxtaposition when seen in the circumferential direction, and being in the vicinity of the interior wall of the vessel, an outlet opening at the bottom of the vessel; a driven rotor, studded with a plurality of blades, coaxially arranged in the interior of said vessel, said rotor having a first ring of blades which is arranged so that it scrapes over the openings of the inlet openings in the form of a knife edge, the blades of the rotor being angled in a conveying manner in the forward direction of the thin layer, said rotor blades being substantially rectangular in shape, with the edge of each rotor blade facing the interior wall of the vessel passing over said wall with its full length at a close distance from the wall; and a plurality of mixing blades mounted in the wall of the vessel on at least one generatrix of the vessel, said mixing blades being adjustable with respect to their angulation and each of said mixing blades projecting into the interior of said vessel between two rings of rotor blades.
