The present invention relates to a process for the production of a reinforced polyamide (rP) in an extruder. In this process, a first mixture (M1), a second mixture (M2) and a third mixture (M3) are added into the extruder, and subsequently at least one carbon material is added to obtain a carbon containing polymerizable mixture (cpM) in the extruder. This carbon containing polymerizable mixture (cpM) is polymerized and subsequently devolatilized to obtain the reinforced polyamide (rP). Furthermore, the present invention relates to the reinforced polyamide (rP) obtainable by the inventive process.

A device according to various embodiments for preparing wet grain can include at least a first screw configured to receive wet grain. A second screw receives the wet grain from the first screw. At least one of a compressing element and a dehydrating element is included with at least one of the first screw and the second screw to cause a physical property change to the wet grain.
