Infrared Core Drying Tunnel for Pulp Molding | Uniform Internal Drying for Complex 3D Shapes

Our specialized infrared drying tunnel provides rapid, uniform, and energy-efficient internal drying for three-dimensional pulp molded products. Utilizing a customizable mix of medium-wave and short-wave infrared emitters, it penetrates thick pulp walls to drive moisture from the core, significantly reducing drying time compared to conventional hot air methods.

• Infeed Conveyor (Synced with forming/pressing station)
• Customizable IR Emitter Array Modules (Top, Bottom, Side configurations)
• Stainless Steel Tunnel with Insulated Panels
• Reflective Cavity for Maximum Efficiency
• Zoned Temperature Control System
• Auxiliary Air Circulation & Moisture Exhaust System
• Outfeed Conveyor
• Central Control Cabinet with PLC and Touchscreen HMI

Ideal for internal drying and moisture reduction of various pulp molded products, including:

• Egg trays and fruit trays
• Disposable tableware (plates, bowls, clamshells)
• Industrial protective packaging
• Cardboard replacement products

• Deep Penetration: Infrared energy dries from the inside out, preventing surface hardening
• Rapid Response & Control: IR emitters heat up and cool down almost instantly for precise temperature management
• Zoned Drying: Independent control of temperature across different sections allows for optimized drying profiles for complex shapes
• High Energy Efficiency: Direct energy transfer to the product and minimal heat loss to the surrounding air
• Reduced Floor Space: Faster drying rates allow for a more compact tunnel compared to convection ovens

We offer highly customizable designs to match your specific product and production line. Options include the number and layout of IR zones, emitter wavelength mix, conveyor width and type, housing dimensions, control system integration, and safety features.

We provide comprehensive support including installation supervision, operational training, process optimization assistance, preventive maintenance plans, and timely spare parts supply.

The equipment is modularly disassembled and securely packed in weatherproof wooden crates. All electrical components are protected for safe long-distance shipping. Standard terms are FOB, with other incoterms available.
