Wood chip drying in Scotland – Expansion of a belt drying system in Arbuthnott
The requirements for modern wood chip drying systems are continuously increasing. In addition to high throughput capacity, energy efficiency, reliable process stability, and the optimal use of available heat sources are becoming increasingly important.
To meet these demands, an existing wood chip drying system in Arbuthnott, Scotland, was expanded with a second large-scale belt dryer. By integrating the new system in parallel with the existing dryer, the overall plant capacity has been significantly increased while making even more efficient use of the available heat.
As part of the project, the complete electrical installation of the new belt dryer was carried out—from the installation of cable trays and wiring to the connection of all drives, sensors, and system components.
Expansion of the existing wood chip drying system
The existing drying system in Arbuthnott was specifically expanded to meet the growing demands of biomass processing. The additional belt dryer operates in parallel with the existing system, significantly increasing the overall drying capacity for wood chips.
Uniform and controlled drying is particularly important in industrial wood drying to ensure the required material quality. The expansion enables the system to process larger volumes of wood chips efficiently while improving overall process stability.
Advantages of a second belt dryer
- Increased overall throughput capacity
- Optimized use of available thermal energy
- Improved operational reliability
- Flexible production capacity
- More energy-efficient biomass drying
Energy efficiency through optimal heat utilization
The project utilizes a CBT-DS-E-2.0 Container Belt Dryer, a solution specifically developed for drying sawdust and other wood-based materials, with throughput capacities of up to approximately 2,700 kg/h of wet material.
However, the key advantage lies not only in the technology itself but in the overall concept. The entire system is built in a containerized design, allowing it to be installed as a plug-and-play solution. For the operator, this means significantly shorter project implementation times and minimal modifications to the existing infrastructure.
Especially in the wood and biomass industry, where production processes often need to operate continuously, this represents a significant competitive advantage.
Why belt dryers are particularly efficient
Belt dryers provide continuous and gentle drying of wood chips, sawdust, and biomass. Controlled airflow and uniform material distribution enable high levels of efficiency
Particularly in large industrial installations, dual-belt or parallel drying systems offer significant advantages over conventional drying technologies.
Electrical installation of the new belt dryer
One of the key advantages of modern belt dryers is the efficient use of available heat sources. Especially in biomass and wood drying, heat recovery plays a crucial role.
By expanding the drying system in Scotland, the existing heat can now be utilized much more effectively. This not only reduces energy consumption per tonne of material but also improves the overall economic efficiency of the drying plant.
Clearly structured processes and uniform heat distribution also ensure consistently high drying quality.
Integration of sensors and drive technology
Modern wood chip drying systems are equipped with extensive sensor technology and automated control systems. Temperature, airflow, material moisture, and drive data must be continuously monitored.
The professional electrical integration of all components ensures that the system can be controlled efficiently and operated with high precision.
Comprehensive testing before commissioning
Following the initial pre-installation, the entire system underwent comprehensive testing.
The following checks were carried out:
- Testing of all drives
- Inspection of sensors and measurement systems
- Verification of all electrical connections
- Testing of all safety functions
- Complete testing of all relevant system components
The electrical installation has therefore been fully completed, and the system is ready for final commissioning.
Why electrical testing is essential
Extensive testing is indispensable before large industrial plants are commissioned. Only thorough testing ensures that all systems operate reliably and that the plant can be operated safely over the long term.
Especially in large-scale belt drying systems, precisely coordinated electrical systems are essential for stable, energy-efficient operation.
Applications of modern wood chip drying
A key success factor of this project was the containerized design of the drying system. While conventional drying systems often require extensive construction work and long installation periods, the container solution could be commissioned within a relatively short time.
For the operator, this not only meant a faster production start-up but also significantly reduced infrastructure investment costs. This advantage is particularly valuable when expanding existing production facilities or operating at temporary sites.
Results that deliver measurable benefits in operation
Today, belt dryers are used in a wide range of applications across the wood and biomass industry.
Typical applications include:
- Wood chip drying
- Sawdust drying
- Biomass drying
- Wood Drying
- Energy and heat generation
- Processing of residual materials
Modern drying technologies enable companies to improve their energy efficiency while enhancing material quality.
Why energy-efficient wood drying is becoming increasingly important
Rising energy costs and growing demands for sustainable production processes are making energy-efficient drying systems more important than ever.
Lower energy consumption
Improved process stability
Higher material quality
Reduced operating costs
Optimal utilization of available heat sources
- Lower energy consumption
- Improved process stability

Frequently asked questions about wood chip drying
During the wood chip drying process, moisture is removed from the material in a controlled manner. Modern belt dryers use heated process air while continuously conveying the material through the system.
Belt dryers operate continuously, are highly energy-efficient, and provide uniform drying of large quantities of material.
Utilizing available heat reduces energy consumption and improves the overall economic efficiency of the drying system.
Belt dryers are suitable for drying a wide range of materials, including wood chips, sawdust, biomass, pet food, food products, and industrial residual materials.
