Wood debarking machine is a high-efficiency, durable, and easy-to-operate wood processing tool, designed to handle various types and sizes of wood. With its high debarking rate, it can quickly and effectively remove the bark, significantly improving production efficiency.
We offer two models of debarkers: vertical and horizontal. The vertical debarker is suitable for logs, trunks, and wood sections with diameters ranging from 5 to 35 cm. The horizontal debarker is designed for trunks, branches, and roots with diameters up to 30 cm, and it can process wood in batches.

Structural features of small wood debarker
With the technical parameters in mind, it is also essential to explore the structural features of our small wood debarker.
Compact ring design
- Integrated structure. Built as a space-saving ring-shaped unit, ideal for small workshops or mobile operations.
- Modular components. Combines host machine, feeding/discharging systems, and transmission into a single compact frame.
Core functional components
- Ring cutters & frame. Equipped with a set of circular blades for efficient bark removal without damaging wood cores.
- High-torque transmission. Utilizes gear or belt-driven systems for stable power transfer, adaptable to varying log diameters (50–300mm).
Automated material handling
- Feeding system. Automatic conveyor belt adjusts speed (0.5–2m/min) to match log size and moisture content.
- Discharging system. Belt-driven exit mechanism sorts peeled logs and bark debris separately for streamlined workflow.
Versatile wood compatibility
- Adapts to moisture levels. Optimized for semi-humid logs (moisture 20–40%) but handles both dry and freshly cut wet wood.
- Multi-species support. Processes softwoods (pine, fir) and hardwoods (oak, birch) with adjustable blade pressure.
Precision peeling performance
- Minimal wood loss. Blade gap settings (1–5mm) ensure 95% bark removal while preserving usable wood volume.
- Uniform surface finish. Ideal for downstream processing into boards, chips, or pulp-grade material.
User-centric enhancements
- Quick blade replacement. Tool-free access to cutters reduces downtime.
- Safety guards. Full enclosure with emergency stop function for operator protection.
Now that we know the structure, let’s delve into the step-by-step process of debarking logs using a vertical log debarker.
How to debark logs with a vertical log debarker?
To begin the log debarking process, place logs, branches, or other types of wood into the drum of the vertical log debarker. Once the wood is loaded, close the feed baffle to secure the materials inside. Start the machine and set it to run in a clockwise direction. As the drum rotates, the wood moves along with it, allowing the peeling knife to efficiently strip the bark from the surface.
After approximately ten minutes of operation, turn off the machine and open the discharge baffle. Then, restart the machine and run it in a counterclockwise direction for about two minutes. This reverse motion helps to automatically eject the peeled wood from the drum. With this method, the log debarking efficiency can reach up to 95%, ensuring a high-quality peeling process.
Features of wood debarking machine
In addition to the operation process, our wood debarking machines offer a variety of features that enhance their efficiency and reliability.
- Various models for different log sizes. The machine comes in multiple models, allowing for efficient peeling of logs with varying diameters. We assist customers in selecting the most suitable model based on their raw material specifications.
- Durable cutting material. Equipped with high-hardness, wear-resistant cutting components, ensuring long service life and reliable performance.
- Ideal for small and medium-sized wood processing plants. Designed to meet the needs of small to mid-scale wood processing businesses with its efficient and consistent operation.
- Low noise and stable performance. Operates with minimal noise, providing a stable working experience with smooth functionality.

Main structure of the horizontal log debarking machine
Understanding the technical parameters, let’s explore the main structural components of the horizontal log debarking machine.
The horizontal log debarker is quite different from the drum type wood debarker in outlook and functions. The main structure of the horizontal wood peeling machine is a U-shaped trough. There are usually one or two spiral cutters inside the tank, which are mainly used for peeling all kinds of logs.
The number of spiral cutters in the machine tank is determined according to the processing capacity and model of the machine. Generally, the log peeling machine with two spiral cutters has a larger processing capacity.
The bottom of the U-shaped groove of the wood peeling machine generally has many square holes, which can make the bark and other debris leak during the processing.
Generally, in many large and medium-sized wood processing plants, producers will also choose to install an automatic conveyor belt under the log peeling tank. So that during the production process, bark and other debris can be automatically transported to a fixed pile to reduce the labor work of manually cleaning the wood peels.
Working principle of the horizontal wood peeling machine
To grasp how the horizontal debarker operates, we need to review its working principle.
The horizontal wood peeling machine can allow the logs or branches used for processing to have a curvature of less than 8%, so it has strong adaptability.
The electric wood peeling machine uses the force generated by the rotor with peeling teeth. This causes the logs to move circularly in the silo groove board and rotate around their axis. Additionally, the logs make irregular jumps during the process.
In this way, between the wood and the teeth, between the wood and the wood, and between the wood and the tank, there will be constant friction, impact, and squeezing, and the bark will be quickly separated, achieving the effect of efficient peeling.
