Working Principle of Three-Pass Wood Chip Dryer
AGICO three-pass drum wood chip dryer adopts an advanced three-pass design, which can save energy to the maximum extent while being highly efficient, ensuring uniformity and efficiency during the wood chip drying process.
1. Material feeding
The wood chips are evenly fed into the inner drum of the dryer via the feeding device. The feeding device can ensure a smooth material flow and avoid uneven drying caused by uneven feeding.
2. Three-pass drum structure
The three-pass drum dryer consists of three coaxial drums: inner drum, middle drum and outer drum. These drums are connected on the same axis, but different airflow paths are formed between them, so that the contact between hot air and materials is more complete, ensuring the rapid evaporation and effective transfer of moisture in wood chips.
Inner drum: Wood chips are in contact with high-temperature hot air. The hot air enters the inner drum through a specially designed nozzle, quickly contacts the wet wood chips, and evaporates the moisture on the surface of the wood chips. The temperature inside the inner drum is relatively high, usually 150℃ to 200℃. Through this high-temperature process, most of the moisture is quickly evaporated.
Middle drum: The humidity begins to decrease through the interaction between the hot air in the inner drum and the wood chips. When the wood chips pass through the middle drum, the temperature will drop slightly, ensuring that the moisture is further evaporated. At this time, the wood chips have reached the initial drying state, the humidity continues to decrease, and the evaporated water vapor is transferred to the outer drum through the middle drum.
Outer drum: In the outer drum, the drying completion of the wood chips almost reaches the ideal state, the temperature further drops and the moisture is close to the emission standard. During this process, the material is still further dried by the hot air, and the movement and turning of the wood chips ensure uniform drying to avoid local overdrying or overwetting.
3. Wood chip turning and uniform drying
In the three-pass drum design, the material will turn over multiple times with the rotation of the drum and the action of internal and external airflow. This continuous turning action allows the wood chips to continuously contact with hot air, ensuring that the moisture of each wood chip is evenly evaporated, avoiding the phenomenon of over-drying or under-drying some wood chips.
4. Water vapor discharge
As the wood chips are dried, the water vapor and hot air generated are discharged through the outer cylinder. The hot air and water vapor in the whole process pass through the effective airflow guidance system, avoiding heat waste and maximizing the drying efficiency.
5. Discharging and finished product output
After three-pass drying, the moisture content of the wood chips has been greatly reduced and finally discharged through the discharging device. The discharging system accurately controls the output speed and quantity of the wood chips to ensure that the dried wood chips are evenly dried and reach the ideal moisture content.

Application Fields of Wood Chip Dryer
AGICO three-pass drum wood chip dryer is widely used in many industries due to its efficient drying performance. Whether it is the production of biomass energy, wood processing, or agricultural and horticultural needs, it can provide an ideal drying solution.
Biomass Energy
Wood chip pellet fuel: Dried wood chips are the main raw material for biomass pellet fuel, which is widely used in industrial boilers, heating systems, and power plants.
Direct combustion power generation: In the field of biomass power generation, wood chips can be directly put into the combustion system as fuel for power generation after drying.
Wood processing
Particleboard production: Wood chip drying is a key link in the production process of particleboard. Dried wood chips can better combined with adhesives to improve the quality of particleboard.
High-density board: The production of high-density boards also depends on the uniform drying of wood chips.
Agriculture and horticulture
Animal bedding: Wood chips are widely used as animal bedding in farms after drying.
Horticulture mulch: Dried wood chips are a common ground cover material in horticulture.
Pulp and papermaking
Pretreatment of pulp raw materials: Wood chips need to be pretreated in the papermaking process, and drying is an essential step.
Selection and Recommendation of Heat Source for Wood Chip Dryer
AGICO triple pass wood chip dryer supports multiple heat sources. Users can choose the most suitable heat source solution according to their production needs, budget, and environmental protection requirements.
If you have a small or medium-sized production scale and have sufficient biomass resources, biomass fuel is the best choice. It is not only energy-saving and environmentally friendly, but also helps you utilize local resources.
If your production requirements are more environmentally friendly and are located in an area with strict emission restrictions, it is recommended to use natural gas or electricity as a heat source. They can meet high environmental standards and have relatively stable operating costs.
If you are in an area with low energy costs and a large production scale, coal as a heat source may be the most economical choice. It is suitable for large-scale and high-intensity production needs and can effectively reduce overall operating costs.
