Paper Core Drying Machine— with heat pump, energy saving ,to drying paper core or paper tuber.In the drying process of the paper tube,it should be known that the water content of the paper tube is not large,which is around 6-7%.
The drying temperature is generaly around 65-70degrees, but dying time of the paper tube has a lot to do,you should take care diameter,thickness and gluing performanceof the paper tube. The greater the thickness and diameter, the more space and time required.
After drying. the straightness and roundhess of the paper ube need to be maintained, axial and radial defomation of the paper tube,must be controledduring the drying process. Therefore, hardness and strength are also important quality indicators for most paper tube manufacturers.
Being one of the renowned dryer in the industry, providing a high-quality of Automatic Paper Tube Dryer.Offering you a complete choice of products which include paper core drying oven, poy dty tube dryer, paper core horizontal oven, paper core oven, paper edge protector drying oven and paper tube continuous dryer.
Paper tube Drying Key Temperature Settings:
- Initial Warming Phase (40-50°C):
- Start at 40-45°C to allow gentle moisture evaporation and prevent thermal shock to the paper tubes,
- Mid-Drying Phase (50-60°C):
- Gradually increase to 50-60°C to accelerate moisture removal, with extended dehumidification cycles to handle bulk evaporation; monitor humidity closely to avoid reabsorption35.
- Final Drying Phase (60-75°C):
- Raise to 60-65°C for thorough drying, reducing humidity to target levels; avoid exceeding 75°C to prevent scorching, delamination, or structural damage16.
- Total drying time typically ranges from 8-15 hours, with incremental temperature adjustments every 2-4 hours, based on tube thickness and ambient conditions45.
️ Critical Considerations:
- Humidity Control: Maintain relative humidity below 15% during the final phase using automated dehumidifiers to ensure consistent results35.
- Safety Limits: Never surpass 70-75°C for any material, as higher temperatures risk fire hazards or quality failures;
- Optimization Tips: Calibrate equipment monthly, and align conveyor systems to prevent uneven heating, ensuring tubes are stacked vertically at ≤70% chamber capacity for airflow efficiency13.

Maintenance & Best Practices
- Daily:
- Empty lint trap post-cycle.
- Inspect for foreign objects (coins, clips).
- Monthly:
- Wipe drum with damp cloth.
- Check vent hose for blockages.
- Material Restrictions:
- NEVER dry rubber-like materials (e.g., foam pads)7.
- Avoid overloading (“Max Load” tags indicate weight limits
