Said device comprises: a reactor chamber (1) having a substantially circular cylinder-shaped upper section (11), which is delimited by two circular surfaces (111, 112) and a circumferential surface (113) and has a longitudinal cylinder axis, and a lower section (12), the upper section (11) and the lower section (12) being connected to one another via the first circular surface (111); an inlet opening (2); a first outlet opening (3), which is arranged in a wall of the lower section (12); a second outlet opening (4), which is arranged in the second circular surface (112) or in the circumferential surface (113) between the inlet opening (2) and the second circular surface (112); and a removal device (51), which is arranged so as to be movable along the longitudinal cylinder axis at least between the second circular surface (112) and the inlet opening (2), and contacts the circumferential surface (113). The invention further relates to a method comprising: feeding an oligomer melt (7) into a circular cylinder-shaped first section (11) of a reaction chamber (1) through an inlet opening (2) tangentially to a circumferential surface (113) of the first section (11); polymerizing the oligomer melt (7) to form a polymer melt (8); removing the polymer melt (8) from the reaction chamber (1) through a first outlet opening (3) of the reaction chamber (1); and removing a gaseous substance (9) from the reaction chamber (1) through a second outlet opening (4) of the reaction chamber (1) above the inlet opening (2). Deposits on at least one inner wall of the first section (11) of the reaction chamber (1) above the inlet opening (2) are removed by a removal device (51).

    Abstract: A continuous method for multi-staged drying and subsequent condensation of solid phase polyamide granulate is characterized in that 1) the pre-drying is carried out in a continuous drying apparatus operated in counter-flow or cross-flow mode with inert gas, steam or a mixture of inert gas and steam at a granulate temperature in the range of 70 to 200°C and 2) the subsequent continuous post-condensation is carried out in a separate shaft with a moving bed at a granulate temperature in the range of 120 to 210°C, wherein the shaft is operated in counter-flow mode with inert gas, steam or a mixture of inert gas and steam, the inert gas is fed at at least two points along the shaft, wherein 15 to 90% of the inert gas is fed at the base of the shaft and 10 to 85% of the inert gas is fed at the upper half below the granulate surface.

    Abstract: The invention relates to a device for the synthesis of a polymer with extraction of a gaseous substance (8) comprising a reaction chamber (1) that comprises a substantially circular-cylindrical upper section (11), which is delimited by two circular faces (111, 112) and a lateral face (113) and has a cylinder longitudinal axis, and a lower section (12), an inlet opening (2), which is arranged in a circular face or the lateral face of the upper section (11), a first outlet opening (3), which is arranged in a wall of the lower section (12), a second outlet opening (4), which is arranged in the lateral face of the upper section (11) and lies opposite the first outlet opening (3), and a stripping apparatus (5), which is arranged such that the stripping apparatus (5) can rotate about the cylinder longitudinal axis and touches both circular faces and the lateral face. Said device can be used in particular for carrying out a method that comprises feeding an oligomer melt (6) into a reaction chamber (1) through an inlet opening (2), polymerising the oligomer melt (6) to form a polymer melt (7), removing the polymer melt (7) from the reaction chamber (1) through a first outlet opening (3) of the reaction chamber, and removing a gaseous substance (8) from the reaction chamber (1) through a second outlet opening (4) of the reaction chamber (1), wherein deposits on at least one inner wall of the reaction chamber (1) are removed by a stripping apparatus (5) and transported into the oligomer melt (6).
