Abstract

Disclosed are techniques for mitigating vent flow into a vent attachment on an extruder vent of an extruder. The vent attachment has a vent attachment port configured to release gases from the extruder vent. The techniques include monitoring temperature via a temperature probe mounted at least partly inside an interior opening of the vent attachment. The temperature probe is communicatively coupled to a programmable logic controller (PLC). A region of the vent attachment adjacent the temperature probe is cooled so as to reduce an operating temperature of the region and of the temperature probe. Vent flow is detected in response to the PLC determining a rate of temperature change of the temperature probe exceeding a predetermined threshold rate and thereby indicating presence of the material in the vent attachment port.
