High-Capacity Double-Deck Natural Gas Drying Oven for Industrial Pulp Molding
Production Line Composition
This space-optimized drying system includes:
  • Motorized Infeed Conveyor – variable speed, compact design, with manual or automatic product loading station
  • Double-Layer Insulated Drying Tunnel – two vertically stacked drying chambers (lower deck + upper deck), high-density rock wool insulation (100-120 mm)
  • Integrated Natural Gas Burner Unit – compact direct-fired burner, stainless steel heat exchanger, modulating control valve
  • High-Efficiency Air Circulation Fans – two fans (one per deck) with variable speed control, adjustable air distribution louvers
  • Exhaust System with Adjustable Dampers – for humidity control and moisture removal
  • Compact PLC Control Panel – wall-mount or machine-mount design, 7″ touchscreen HMI, basic recipe storage (up to 30 recipes)
  • Temperature Monitoring System – PT100 sensors in each deck with digital display
  • Outfeed Conveyor – with product collection tray or manual unloading station
  • Gas Safety Interlock System – flame detector, gas leak sensor, manual shut-off valve, emergency stop button
The system is designed for a compact footprint, suitable for facilities with limited floor space. The total length can be as short as 6 meters for small-scale production.
Product Overview
This Compact Double-Layer Natural Gas Dryer is specifically designed for small to medium-sized pulp molding operations, pilot production lines, or facilities with severe space constraints. By stacking two drying chambers vertically, this system achieves double the drying capacity of a single-deck dryer while occupying the same floor area – typically requiring only 6-15 meters of linear space compared to 12-30 meters for a comparable single-deck system.
The dryer uses direct gas-fired heating with forced hot air circulation. Natural gas is burned in a compact, high-efficiency modulating burner, and the hot air is circulated independently through each deck. The lower deck and upper deck have separate temperature controls and airflow adjustments, allowing flexible operation for different product types or different drying stages.
The compact design is ideal for manufacturers who are:
  • Expanding production but have limited floor space
  • Setting up a pilot or R&D drying line
  • Producing small-batch, high-value pulp molded products
  • Operating in multi-story facilities where horizontal space is limited
  • Retrofitting an existing production line with limited space for additional drying capacity

Frequently Asked Questions
Q1: How much floor space does the compact double-layer dryer require compared to a single-deck dryer?
A1: The compact double-layer dryer typically occupies 40-50% less floor space than a single-deck dryer with comparable capacity. For example, a single-deck dryer requiring 15-20 meters of linear space can be replaced by a double-deck unit requiring only 8-12 meters. The exact footprint depends on the selected tunnel length and width.
Q2: Can I start with a shorter tunnel length and add sections later as production grows?
A2: Yes. The modular design allows you to start with a shorter tunnel (e.g., 6 meters) and add additional tunnel sections later to increase drying capacity. This is a cost-effective way to scale your production without replacing the entire dryer. Please consult our engineering team for the modular expansion design.
Q3: Is this dryer suitable for drying thin-wall products like disposable plates?
A3: Yes. The adjustable deck clearance (150-400 mm) and variable belt speed allow precise control for thin-wall products. The forced hot air circulation ensures uniform drying without warping. For very thin products (e.g., 0.5-1 mm thickness), we recommend the PTFE mesh belt option to prevent sticking.
Q4: What is the power consumption of the compact dryer (excluding gas)?
A4: The electrical power consumption is relatively low – typically 5-15 kW depending on the number of fans, conveyor motors, and control system. The majority of the energy input comes from natural gas, which is generally more cost-effective than electric heating for industrial drying applications.
