High-Speed Infrared Drying Tunnel for Pulp Molding with Multi-Layer Continuous Drying Up to 30 m/min and Customizable Width & Length
Multi-Layer Continuous Drying Infrared Drying Tunnel
,Up to 30 m/min Infrared Drying Machine
,Customizable Width & Length Infrared Drying System
This infrared drying production line is engineered for rapid, energy-efficient drying and curing of water-based, solvent-based, or UV-curable coatings applied to molded pulp tableware and packaging products. The system uses medium-wave or short-wave infrared emitters to directly transfer heat to the coating and substrate surface, significantly accelerating water evaporation and crosslinking reactions.
Unlike conventional hot air drying methods that heat the surrounding air, infrared drying delivers direct energy transfer to the product—achieving drying time reductions of 25-90% and energy savings up to 20-30% compared to convection methods. Short-wave infrared reaches full power in 1-2 seconds with no preheating delay, reducing idle energy consumption.
For complex-shaped products with deep cavities or varying thicknesses, the system can be equipped with customizable rotating fixtures, tilting pallets, or strategically placed emitter layouts to ensure uniform heat distribution across all surfaces—preventing wet spots, warping, and surface defects.
