Material agglomerating in the drying hopper
Fenómeno do problema
The material forms hard lumps after drying and cannot be used normally
Análise das causas
Drying temperature is too high, exceeding the material softening point or Tg; drying time is too long, causing particle surfaces to soften and stick; material pressurization in the hopper causes agglomeration
Solução
Reduce drying temperature to 10-20°C below the softening point/Tg; control material layer thickness to reduce bottom pressure; use a drying hopper with stirring function
Conclusão principal
Agglomeration causes material waste and loss of drying effect
