Method for processing solid plastics particles from a polycondensate by means of a multi-rotation system, having at least the following steps: a) drawing in of the plastics particles and at least partial melting of the plastics particles in a first extruder section with at least one extruder screw rotating in a housing recess of a housing; b) transfer of the at least partially melted plastics composition into a second extruder section, which is designed as a multi-screw extruder section with a poly-rotation unit and a plurality of satellite screws rotating therein, the diameter of the poly-rotation unit being increased compared with the screw diameter of the first extruder section and a transition cone being formed between the extruder sections (1, 2) and a conical gap being formed in relation to the housing; c) forwarding of the plastics composition which has been completely melted in the drive zone (23, 24, 25) through a degassing zone in which a vacuum is applied; d) removal of volatile constituents from the plastics melt in the degassing zone; e) transfer of the plastics melt into a discharge extruder section, characterized in that, - in step b), the partially melted plastics composition as supercooled plastics melt contains between 5% by volume and 50% by volume of non-melted and non-dehumidified plastics particles, - in that the remaining plastics particles are subjected to pressureless plasticization by at least parts of the plastics composition being passed through a drive zone (23, 24) which is located downstream of the transition cone in a flow direction and which has exposed drive pinions of the satellite screws, and - in that, very shortly before entering the vacuum zone, the supercooled plastics melt is reheated to such an extent that the remaining plastics particles melt and thereby release the stored residual moisture. a) drawing in of the plastics particles and at least partial melting of the plastics particles in a first extruder section with at least one extruder screw rotating in a housing recess of a housing; b) transfer of the at least partially melted plastics composition into a second extruder section, which is designed as a multi-screw extruder section with a poly-rotation unit and a plurality of satellite screws rotating therein, the diameter of the poly-rotation unit being increased compared with the screw diameter of the first extruder section and a transition cone being formed between the extruder sections (1, 2) and a conical gap being formed in relation to the housing; c) forwarding of the plastics composition which has been completely melted in the drive zone (23, 24, 25) through a degassing zone in which a vacuum is applied; d) removal of volatile constituents from the plastics melt in the degassing zone; e) transfer of the plastics melt into a discharge extruder section, - in step b), the partially melted plastics composition as supercooled plastics melt contains between 5% by volume and 50% by volume of non-melted and non-dehumidified plastics particles, - in that the remaining plastics particles are subjected to pressureless plasticization by at least parts of the plastics composition being passed through a drive zone (23, 24) which is located downstream of the transition cone in a flow direction and which has exposed drive pinions of the satellite screws, and - in that, very shortly before entering the vacuum zone, the supercooled plastics melt is reheated to such an extent that the remaining plastics particles melt and thereby release the stored residual moisture.
