Product Description
The High-Speed Energy-Efficient 2.2M Infrared Drying Conveyor is a professional industrial drying system specifically designed for fast, uniform drying of water-based and solvent-based surface coatings on molded pulp products such as tableware (plates, bowls, lunch boxes, trays), industrial packaging inserts, food containers, and other coated pulp articles. Utilizing medium-wave infrared heating technology, this equipment provides fast, targeted heat directly to the coated surface, accelerating moisture evaporation and coating curing with high energy efficiency-3. The directly absorbed infrared energy rapidly heats the coating layer without the need for heating the entire surrounding air volume in the workshop, significantly reducing energy waste and operational costs. The integrated hot air circulation assist system enhances heat uniformity, preventing issues such as pinholing and incomplete curing. With processing speeds up to 30 m/min, this high-speed 2.2-meter-wide infrared drying conveyor is the ideal choice for medium-to-high volume pulp molding manufacturers seeking to improve throughput while maintaining consistent, high-quality surface finish and minimal energy consumption.

FAQ
Q: What types of coatings can be dried with this equipment?
A: This IR drying conveyor is compatible with a wide range of coating formulations — primarily water-based barrier coatings and solvent-based coatings commonly used in molded pulp applications. Medium-wave IR is particularly effective for water-based coatings due to its strong affinity for water molecules, ensuring efficient moisture removal without damaging the substrate-. UV-curable coatings are better processed on UV curing systems; please consult our technical team for application-specific recommendations.
Q: What is the 2.2-meter effective working width? Can this be adjusted?
A: Yes, the machine is fully customizable. While 2200mm is our standard recommended width for large-format molded pulp products, we offer effective working widths ranging from 600mm to 2600mm. The entire line configuration — including conveyor width, emitter array layout, and tunnel dimensions — is adjusted accordingly to ensure optimal drying uniformity across your specific product dimensions.
Q: How does infrared drying compare to hot air drying for molded pulp coatings?
A: Infrared drying offers significant advantages for coated molded pulp. IR transfers heat directly to the coated surface without heating the surrounding air, resulting in up to 30% lower energy consumption compared to conventional hot air dryers-. Additionally, IR provides faster response times (seconds vs. minutes), more precise temperature control, and reduces surface defects such as pinholing and blistering that can occur with uncontrolled hot air drying.
Q: Is a cooling section necessary after IR drying?
A: Yes, a cooling zone is recommended for most applications. After exiting the high-temperature drying zone, coating and substrate surfaces require controlled cooling before handling to prevent heat-related deformation or damage. Our systems include customizable cooling sections from 1–2 meters with ambient or forced-air cooling options.
Q: Can this line be integrated with automatic coating equipment?
A: Absolutely. The line is designed as a modular system that integrates seamlessly with upstream coating equipment such as roller coaters, spray coating lines, curtain coaters, and automatic dispensing systems. Our engineering team provides full integration planning support to ensure smooth material flow from coating application through drying to final collection.
Q: What is the typical energy consumption?
A: Energy consumption varies based on the number of heating zones, operating temperature, conveyor speed, and product throughput. The integrated hot air circulation assist system optimizes energy use by recirculating heated air within the tunnel, reducing exhaust losses. Optional heat recovery systems can further reduce energy costs by up to 20%. For specific energy consumption estimates based on your production parameters, please request a customized performance calculation from our sales engineering team.
Q: What is the warranty period?
A: Standard warranty is 12 months from the date of commissioning, covering manufacturing defects in materials and workmanship. The warranty includes all electrical, mechanical, and structural components (excluding consumables such as belts, IR emitters beyond rated lifespan, and wear parts). Extended warranty options (24 or 36 months) are available upon request.
Q: Can the machine handle different product heights/shapes?
A: Yes, the product height clearance is adjustable between 80–180mm as standard. For deeper products or irregular shapes, custom adjustments can be made including increased clearance height and modified IR emitter positioning to ensure uniform drying across complex product geometries.
