Abstract: A device for continuous production of an extrudate from finely divided plant material and a thermoplastic material. When viewed in an extrusion direction, first the finely divided plant material and then the thermoplastic material are fed to an extrusion device, which can be a twin-screw extruder. The fed-in materials are mixed with one another, degassed and jointly extruded from the extrusion device and thus form the extrudate, and the plant material is embedded in the thermoplastic material, wherein the plant material and the thermoplastic material are fed into the extrusion device at a common position or two directly successive positions. The thermoplastic material is plastified in a separate plastifier extruder before being fed into the extrusion device and is fed from the extruder to the extrusion device in a plastified state, and the plant material is then degassed together with the thermoplastic material.

Abstract: The invention relates to a process and a device for the continuous production of an extrudate from finely divided plant material and a thermoplastic material, in which, as viewed in the extrusion direction (E), firstly the finely divided plant material and then the thermoplastic material are fed to an extrusion device (1), which is embodied as a twin-screw extruder, the fed-in materials are mixed with one another, degassed and jointly extruded from the extrusion device thus forming the extrudate (6), and the plant material is embedded in the thermoplastic material, wherein the plant material and the thermoplastic material are fed into the extrusion device at a common position or two directly successive positions, the thermoplastic material is plastified in a separate plastifier extruder (4) before being fed into the extrusion device and is fed from said extruder to the extrusion device (1) in a plastified state, and the plant material is then degassed together with the thermoplastic material.

Abstract: An extruder drive has a housing, at least two extrusion worms each having a drive shaft extending into the housing, and at least one drive motor including at least one cylindrical stator fixed in the housing and a cylindrical rotor cooperating with the stator so as to be rotatably driven by the stator. The rotor surrounds the drive shafts, and each of the drive shafts is independently connected to the rotor for driving thereby.
