Industrial IR Drying Tunnel for Screen Printing & Inks
Customizable Belt Width (400-2000mm) & Heating Zones
Product Overview
This customizable IR drying line is an industrial tunnel-type drying system using medium-wave or far-infrared heating technology for efficient drying and curing of coatings, inks, and adhesives on various substrates. Available in standard screen printing drying, high-temperature glass processing, and precision electronics curing configurations.
The system is fully customizable in belt width, heating length, number of heating zones, temperature range, and automation level. Unlike conventional hot air drying, IR heating transfers energy directly to the product surface without heating the surrounding air, resulting in faster drying times, lower energy consumption, and reduced floor space requirements.
This IR drying line is ideal for drying solvent-based and water-based inks after screen printing, pad printing, and spray coating, as well as curing adhesives, drying coatings on glass/ceramics, and processing optical films and electronic components.
Working Principle
Infrared radiation from heating tubes penetrates the coating/surface, causing rapid solvent evaporation or cross-linking polymerization (for UV/thermal curing). Optional hot air circulation enhances temperature uniformity to ±2°C within the chamber.

Frequently Asked Questions
Q1: What is the difference between IR drying and hot air drying?
A: IR drying uses infrared radiation to directly heat the coating/product surface without heating the surrounding air, resulting in faster drying times (up to 70% faster) and lower energy consumption. Hot air drying heats the entire chamber and relies on convection to transfer heat to the product, which is slower and less energy-efficient but provides more uniform temperature distribution for heat-sensitive products.
