Material Drying

Material agglomerating in the drying hopper
Problem Phenomenon
The material forms hard lumps after drying and cannot be used normally
Cause Analysis
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
Solution
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
Key Takeaway
Agglomeration causes material waste and loss of drying effect
