Pelletizing apparatus for the production of polymer pellets

A pelletizing apparatus for a production of thermoplastic pellets, the pelletizing apparatus comprising:

• a filter device configured to be connected in fluid-conducting relationship to a melt feed for separating dirt particles and impurities from a polymer melt;
• a granulator arranged downstream of the filter device and configured to produce polymer pellets;
• a water treatment device configured to clean process water from the dirt particles and impurities of the polymer melt;
• and
• a control means configured to control at least one of the filter device, the granulator, and the water treatment device, wherein the control means is configured to provide a control parameter for the least one of the filter device, the granulator, and the water treatment device;
• machine-readable and machine-writable identification means configured to store and provide component-specific information, wherein the identification means is associated with a component of the at least one of the filter device, the granulator, and the water treatment device in a flow path of the polymer melt or the process water;
• a reading device connected in signal-conducting relationship to the control means and configured to receive the component-specific information from the identification means;
• and
• a writing device configured to write and/or overwrite the identification means with the component-specific information,
• wherein the control means is configured to (a) adapt the control parameter in dependence on the component-specific information to thereby adapt operation of the component of the at least one of the filter device, the granulator, and the water treatment device in the flow path of the polymer melt or the process, (b) provide the component-specific information, and (c) execute a diagnostic process based on the component-specific information.
