Energy-Saving Infrared Drying Tunnel for Pulp Molding with Uniform Moisture Removal and Low Deformation

Traditional pulp drying relies on large drying rooms or natural sun drying, which are energy-intensive and slow, often causing shrinkage or deformation. This infrared drying tunnel delivers focused radiant heat directly to the wet pulp, achieving uniform moisture removal with lower energy consumption per unit and significantly reduced product deformation. The system is designed for pulp molded products requiring tight dimensional tolerances, including precision industrial packaging, electronics cushioning, and premium food service ware.

• Direct Radiant Heating: Infrared energy is absorbed by the water within the pulp, heating the product body directly rather than the surrounding air — reducing energy waste.
• Uniform Moisture Removal: Multi-zone gradual drying profile prevents surface crusting and internal stress — minimizing warpage and cracking.
• Low Deformation: Controlled temperature ramp-up and humidity-managed exhaust ensure dimensional stability of thin-wall and complex products.
• Energy Efficient: Thermal insulation and direct heating reduce heat loss from the tunnel shell — lower energy consumption per unit.
• Process Traceability: Real-time temperature and humidity display with data logging for quality control.

• High-Quality Pulp Molded Products: Precision industrial packaging, electronics cushioning, medical tray inserts, and premium food service ware requiring tight dimensional tolerances.
• Thin-Wall Products: Cups, bowls, and clamshells where deformation control is critical.
• Multi-Product Lines: Manufacturers producing multiple pulp molded product types requiring different drying profiles.
• Energy-Conscious Operations: Factories seeking to reduce energy consumption per unit compared with traditional drying rooms.
