How Our Wood Drying Kiln Works
Vacuum Dehydration
Our stainless steel vacuum pump creates a vacuum, efficiently drawing moisture out of the wood. This allows the wood to dry at low temperatures below 55°C, preventing damage while speeding up the drying process.
High-Frequency Waves
Our kiln uses high-frequency waves to penetrate deeply into the wood, ensuring even drying from the core to the surface. This technology guarantees that thick wood and hardwoods dry thoroughly, with no uneven moisture distribution.
Cooling System
After drying, the system separates and cools the hot air and water, ensuring optimal temperature control throughout the process. This helps prevent over-drying and damage, maintaining the wood’s quality.
No Cracks, No Warping
Vacuum and low-temperature drying protects your wood from cracks, warping, and color fading—preserving its natural beauty and ensuring exceptional quality. A perfect solution for premium and delicate hardwoods.
Perfect for Thick and Expensive Wood
This kiln is ideal for drying thick slabs, veneers, hardwoods, and high-value wood types. It can even handle wood thicker than 50 cm, drying it evenly in 7–12 days per cycle depending on the wood type.
Rapid Moisture Removal
Under vacuum conditions, moisture boils at 35–50°C, vaporizing quickly and speeding up the drying process. This helps save both time and energy.
Double Drying Speed
The vacuum system creates a pressure difference, which accelerates moisture removal, doubling the drying speed compared to conventional methods.
Increased Production Efficiency
By drastically reducing drying time, our kiln allows you to process more wood in less time, increasing your output and overall production efficiency.

Main components of vacuum kiln
Main body of vacuum kiln
Why our vacuum kiln cabinet is square? It is based on our many years of wood drying experience.
First, the square has stability and will not collapse.
Second, the square vacuum kiln can load more wood.
Third, the square is easy to operate in use.
High Frequency Generator
The vacuum high-frequency generator is the core technology of the vacuum kiln. It is heated by a high-frequency medium. The principle is to use an electric field to make the wood moisture vibrate at a high speed. It will generate heat from the inside to the outside. It is a direct heating method. The temperature inside and outside is uniform.
Cooling Tower
The cooling tower is an automatic cooling system. Hot steam will appear during the heating process of wood. Its function is to separate the water and steam, and then discharge the moisture from the wood.
Hydralic Pressure System
There is a set of hydraulic device in the vacuum kiln. We all know that wood will deform and warp when heated. This device can solve the problem of wood deformation. It can provide 6-8 tons of pressure to prevent wood deforming and warping.
Motor Drive Timber Cart
Automatic feeding device, when we investigated the wood drying market, we found that it was very laborious and inconvenient for workers to load and unload wood. Our team developed an automatic feeding device, which can greatly reduces labor.
Pneumatic valve & Stainless Steel Pipes
The reason why our drying kiln is of good quality is because the stainless steel vacuum pump and solenoid valve are used, and all the pipes are made of 304 stainless steel, which ensures the safety and reliability of the users in use.
