Thermal Dryer System for Plastic Recycling
Rumtoo’s thermal dryer removes residual moisture from plastic flakes and films to a typical 1–3% after washing and dewatering. Insulated ducting, balanced airflow and optional heat recovery deliver stable extrusion and pelletizing results with lower energy use.
- Consistent low moisture for steady output
- Energy‑efficient insulation and air management
- Easy access for cleaning and maintenance

Why Choose Rumtoo
A clear side‑by‑side comparison versus a traditional hot‑air dryer.
| Feature | Rumtoo Thermal Dryer | Traditional Hot‑Air Dryer |
|---|---|---|
| Typical final moisture | 1–3% (with upstream dewatering) | 3–8%+ (less consistent) |
| Energy efficiency | Insulated ducts + optional heat recovery | Uninsulated sections, higher losses |
| Temperature control | PID control, alarms, recipes | Basic thermostat, wider swings |
| Throughput stability | Balanced airflow, steady dwell time | Fluctuations, risk of over/under‑drying |
| Maintenance & cleaning | Quick‑open sections, easy access | Fixed ducting, time‑consuming |
| Line integration | Matches Rumtoo washers & pelletizers | Manual adaptation required |
| Dust control | Cyclone + optional bag filter | Basic cyclone only |

Service & Integration
Rumtoo provides end‑to‑end support across washing, drying, and pelletizing, so your thermal dryer slots seamlessly into existing lines.
How It Works
Three coordinated stages deliver uniform, low‑moisture output.
Washed flakes or films enter from the washer/centrifuge with reduced surface water.
Heated air moves material through the drying pipe at controlled velocity for efficient moisture removal.
Dry material is separated from air via cyclone; optional bag filters capture fines for a cleaner plant.
Typical Applications
Used by Rumtoo customers in bottle‑to‑bottle, film, and rigid plastics lines.
PET Flakes
Post‑consumer PET flakes after hot wash for stable IV and low moisture.
HDPE/PP Flakes
Cap, label, and rigid packaging flakes pre‑pelletizing or extrusion.
LDPE/LLDPE Films
Printed and unprinted films following squeezer/centrifuge dewatering.
Regrind & Pellets
Pre‑heating or final drying to improve extruder stability and output.
Frequently Asked Questions
What final moisture can Rumtoo’s thermal dryer achieve?
When paired with upstream washing and mechanical dewatering, typical results are 1–3% final moisture depending on material, inlet moisture, and temperature settings.
How is it different from a centrifugal dryer?
A centrifugal dryer removes bulk surface water mechanically and is ideal as the first drying stage. The thermal dryer uses heated air to remove remaining moisture for stable extrusion or pelletizing.
How do I select the right model?
Sizing considers throughput (kg/h), inlet moisture, target outlet moisture, available footprint, and power. Rumtoo will match blower size, heater power, and pipe geometry to your inputs.
What about energy use and maintenance?
Insulation and heat‑recovery options help lower consumption. Routine tasks include checking filters, seals, insulation integrity, and cleaning the cyclone/bag filter per schedule.
Can it integrate with Rumtoo washers and pelletizers?
Yes. The dryer interfaces with Rumtoo washing lines and pelletizers; we provide matched ducting, controls, and support for start‑up and tuning.
