Inconsistent Moisture Content of PBT Pellets
Fenómeno do problema
The moisture content of the same batch of PBT pellets after drying is uneven.
Análise das causas
The material flow in the drying hopper is uneven (the first-in-first-out principle is broken), and the drying time is insufficient, so some particles are not fully dried.
Solução
Use a mixing hopper to ensure uniform drying; ensure sufficient drying time; test the moisture content after drying.
Conclusão principal
The drying uniformity of PBT is the prerequisite for product consistency.
