Why Effective Drying is Non-Negotiable
Excess moisture in recycled plastics leads to poor-quality end products, including weakened structural integrity, surface imperfections, and processing difficulties. Our system directly addresses these critical challenges.
-
Challenge: Moisture Contamination
Lingering moisture after washing causes defects, reduces material strength, and can damage processing equipment.
-
Solution: Efficient Moisture Removal
Our system provides a reliable, high-efficiency solution to reduce moisture content below 5% before further processing.
Key Features of Our Pipe Drying System
-
Robust 304 Stainless Steel Construction
Built with 2mm thick, corrosion-resistant 304 stainless steel for long-term performance in demanding recycling environments.
-
Adjustable Self-Heating Capabilities
A powerful 36-70 KW heating range allows for precise temperature control tailored to different types of plastic.
-
Efficient Moisture Reduction
Combines powerful heating with a wind-powered delivery mechanism for consistent, thorough drying to below 5% moisture.
-
Optimized Material Handling
An integrated wind delivery motor ensures plastic material is evenly spread and efficiently transported to the next stage.
Technical Specifications
Key parameters for reference. All specifications can be customized to match your material type, throughput, and facility layout.
| Parameter | Specification |

| Outlet Moisture Content | < 5% (1–2% achievable depending on material) |
| Pipe Material | 304 stainless steel, 2 mm wall thickness |
| Compatible Materials | PET flakes, HDPE, LDPE, PP granules and film |
| Configuration | Customizable pipe length, diameter, and heating stages |
| Integration | Downstream of centrifugal dewatering; upstream of extrusion/pelletizing |
How It Works: A Simple & Effective Process
Our system uses a combination of heated air and powerful conveyance to efficiently remove moisture from plastic materials in a continuous flow.
-
1. Material Feeding
Washed plastic flakes or granules are fed into the inlet of the pipe system.
-
2. High-Speed Conveyance
A powerful blower pushes the material through the stainless steel pipeline at high speed.
-
3. Intense Heating & Evaporation
As material travels, the self-heating system raises the air temperature, causing surface moisture to rapidly evaporate.
-
4. Dried Material Discharge
The now-dry material is separated from the hot, moist air in a cyclone separator and discharged for the next process.
Pipe Dryer vs. Centrifugal Dewatering Machine
Both machines remove moisture, but they work differently and serve different stages of the drying process. Understanding the difference helps you choose the right configuration.
| Feature | Pipe Drying System | Centrifugal Dewatering Machine |
|---|---|---|
| Drying Method | Thermal (hot air evaporation) | Mechanical (centrifugal force) |
| Moisture Removal | ✔ Residual moisture (surface & internal) | ⚡ Bulk surface water only |
| Final Moisture Level | ✔ Below 5% (as low as 1–2%) | ⚡ Typically 10–20% remaining |
| Suitable for Soft Film | ✔ Yes | ✔ Yes (with squeeze press version) |
| Suitable for Rigid Flakes | ✔ Yes | ✔ Yes |
| Position in Line | After centrifugal dewatering | Before pipe or thermal drying |
| Ready for Extrusion? | ✔ Yes (direct feed) | ✘ Requires further drying step |
