Moisture regain in PET drying hopper
문제 현상
PET pellets quickly absorb moisture and regain humidity after being discharged from the drying hopper, and the drying effect is lost.
원인 분석
Dried material is exposed to air for too long (>30min); the connecting pipe from the hopper to the barrel is not sealed; ambient humidity is high.
해결 방법
Shorten exposure time to <15min; use sealed insulated conveying pipes; control workshop humidity <40%RH.
핵심 요약
Moisture regain prevention management after PET drying is an important link in ensuring processing quality.
