Pipeline Hot Air Drying System
Dry washed plastic flakes and regrind quickly and consistently with a high‑velocity hot air pipeline. Designed to reach less than 2% final moisture, this system improves pelletizing stability, reduces defects, and helps you run higher-throughput washing lines.
Pipeline Hot Air Dryer Benefits
Maximize Material Value
Produce premium-grade recycled plastics that command higher prices. Our system guarantees the <2% moisture content critical for flawless pelletizing and molding.
Boost Your Throughput
The powerful 72 kW heating and 30-meter pipeline enable continuous, high-volume processing, minimizing bottlenecks in your washing line.
Lower Operational Costs
High-grade insulation reduces energy consumption by up to 20%, while the durable SU304 stainless steel construction minimizes maintenance and ensures a 10+ year lifespan.
Pipeline Hot Air Dryer Design & Components
Heavy-Duty Construction for 24/7 Operation
Built to withstand the harshest industrial environments, our system combines superior materials for maximum longevity:
- Material Contact Parts: Corrosion-proof SU304 Stainless Steel prevents contamination and ensures the purity of your recycled plastics.
- Structural Frame: A robust frame from heavy-gauge carbon steel provides unwavering stability for continuous operation.
High‑Velocity Hot Air Performance
A powerful 72 kW heating unit and an 11 kW fan create a torrent of precisely controlled hot air. This ensures every flake and granule is dried uniformly and rapidly, slashing processing times and preserving material integrity.
Ideal Applications for PET/HDPE/PP
This hot air pipeline dryer is a strong fit for washed rigid plastics and regrind where stable moisture and continuous output matter most.
Post‑consumer PET Bottle Flakes
Reduce moisture for consistent IV and stable extrusion/pelletizing after washing.
Post‑industrial HDPE Regrind
Improve feeding and melt stability by removing surface moisture and residual water.
Washed PP Granules
Lower moisture before compounding to reduce bubbles, splay, and downtime.

System Overview & Material Samples
FAQ
What is a pipeline hot air drying system?
It is a continuous drying unit that uses a high‑velocity hot air stream to convey and dry washed plastic flakes or regrind through a pipeline, helping reduce moisture before pelletizing or compounding.
What materials work best with this system?
Typical targets include PET flakes, HDPE/PP regrind, and other washed rigid plastics. Material shape, size, and inlet moisture affect achievable performance—share your feedstock details for a recommendation.
What final moisture can I expect?
With the right configuration, many installations target less than 2% final moisture. The exact result depends on material type, inlet moisture, throughput, and pipeline length/temperature settings.
How do I size the system for my washing line?
We size heating power, airflow, and pipeline length/diameter based on your target capacity (kg/h), material type, and inlet/outlet moisture. Send your line throughput and material photos for faster selection.
