Single Drum Dryer Specialized for Wood Pellet Production Lines Chipper Dryer

Product Overview

In wood pellet production, raw material moisture content is critical to final pellet quality and energy efficiency. Our Single Drum Dryer is specifically designed for biomass pellet lines to efficiently remove excess moisture from materials such as wood chips, sawdust, shavings, bark, and other biomass feedstocks. It ensures that the material entering the pelletizing process reaches the optimal moisture range (approximately 10%–18%). The dryer features a compact structure, high thermal efficiency, and stable operation, making it an ideal choice for medium to large wood pellet manufacturers.

Working Principle

The material is fed into the rotating drum through the inlet. Inside the drum, specially designed lifting plates lift and disperse the material into an even curtain. The material then comes into full contact with hot air from a hot air furnace or biomass burner, achieving rapid heat exchange. Moisture evaporates and is removed through the exhaust system. The dried material is discharged at the outlet and proceeds to the next process stage.

Key Advantages

• High Efficiency & Energy Saving
  Optimized hot air and material contact path increases thermal efficiency by 15%–20%. Drum speed and hot air temperature are adjustable to suit different raw materials and production capacities.
• Uniform Drying, Stable Quality
  Special lifting plate design ensures the material moves forward in a spiral, preventing local overheating or under-drying. The output moisture content is evenly controllable.
• Robust Construction, Easy Maintenance
  Made of wear-resistant steel plate with heavy-duty supporting rollers, ensuring smooth operation and low failure rate. Large maintenance doors allow easy cleaning and servicing.
• Adapts to Various Biomass Materials
  Suitable not only for wood-based materials (pine, poplar, oak, etc.) but also for straw, bamboo shavings, palm fiber, bagasse, and other fibrous materials.
• Environmentally Friendly
  Can be equipped with a dust collection system (cyclone separator + baghouse filter) to ensure exhaust emissions meet environmental standards, enabling green production.
