Abstract

The invention relates to a device for the implementation of a method for the production of pellets of polyamide 6 or copolyamides. The method can include production of a melt of polyamide 6 or copolyamides by means of polymerization, production of pellets from the melt by means of underwater pelletization into a process fluid, removal of the pellets from a site of underwater pelletization in the process fluid, supply of the pellets in the process fluid to an extraction stage, extraction of low-molecular components as extract, and drying of the pellets after extraction, wherein the underwater pelletization stage and the extraction stage take place using the same process fluid.
