Plastic Drying Systems for Recycling
Achieve <3% Moisture · Increase Throughput · Maximize Value
Industrial-scale dewatering and drying systems for washed plastic films and rigid flakes — engineered for stable extrusion, consistent pellet quality, and lower operating costs across PE/PP film and PET/HDPE rigid flake recycling lines.
Drying is the final quality gate before pelletizing
Most lines remove bulk water mechanically (squeezer or centrifugal dryer) before final hot-air drying. Proper moisture control supports stable extrusion and higher pellet value. If you plan downstream extrusion, see Plastic Pelletizers.
Technology for Peak Performance
High-Efficiency Dewatering and Drying
These systems run continuously for mixed plastic streams and deliver low residual moisture before pelletizing.
-
Precise Moisture Control
Final moisture can reach 1-3% for films and under 2% for rigid flakes.
-
Mechanical and Thermal Paths
Use centrifugal, squeezing, or thermal stages based on material behavior and utility limits.
Line-Level Integration
Each module connects with upstream washing and downstream extrusion to keep output and flow stable.
-
Material Range
Configured for PE/PP film, PET flakes, and rigid HDPE/PP.
-
Energy Strategy
Mechanical dewatering lowers thermal load and reduces operating cost.
Higher Throughput
Water removal reduces bottlenecks and increases practical line output.
Better Pellet Quality
Stable moisture helps prevent extrusion defects and improves finished pellet consistency.

Frequently Asked Questions
What is the difference between mechanical and thermal drying?
Mechanical dewatering (squeezer or centrifugal dryer) removes bulk water with lower energy. Thermal drying then evaporates remaining moisture for low final values, often required for PET and higher-spec output.
Which drying system is right for my plastic material?
It depends on material type and moisture target. For PE/PP films, a film squeezer is often used. For rigid flakes such as PET, centrifugal drying plus pipeline hot-air drying is commonly selected.
What final moisture level can I expect?
Typical targets are 1-5% for films with squeezing and under 2% for rigid flakes with centrifugal and thermal stages. Final values depend on feed moisture and configuration.
Can you design a complete washing, drying, and pelletizing line?
Yes. The line is configured from feedstock, contamination profile, throughput, and moisture target. Drying modules are selected to keep extrusion stable and pellet quality consistent.
