Main Advantages Of High Frequency Vacuum Drying Technology

High-frequency waves can penetrate wood deeply and dry wood from core to wood surface wholly and uniformly from the ever beginning. Even thick wood can also be well heated. Meanwhile, under vacuum conditions, wood moisture can be boiled at 35-50 degrees and vaporize rapidly, which can save both time and energy. And low-temperature wood drying can guarantee wood quality to avoid the crack problem. The vacuum system will suck wood moisture out due to pressure difference which double increases wood drying speed. The result of the combination is that even more than 50cm thick wood can be dried by our high-frequency vacuum wood dryer machine with uniform moisture content within two weeks. Normally Drying time for one cycle is 7-12 days.

1. Stable wood drying without defects

The wood is drying under vacuum conditions which allows the water to boil at a low temperature like 35℃,then it can be vaporized fast.Low-temperature drying solves the problems of wood cracking, deformation, and discoloration, especially for precious timber sensitive to temperature.

2. Fast wood drying

High-Frequency makes the wood heated from core to surface wholly and evenly, it will create a temperature gradient of internal high and external low and then vacuum pressure make water drain out very quickly. For the 8cm thick Africa rosewood from 40-50% moisture content to reach 8-10% moisture content, it only take 7 days.

3. High-quality wood drying result

High-frequency vacuum wood dryer machine is equipped with hydraulic pressure system on the top, the hydraulic pressure system supply 4-6 tons pressure on the wood stacking to prevent wood deforming and bending. We use stainless steel 304 to make the pressure plate.

4. Easy operation

PLC control system and Pneumatic system make the machine easy to operate. It is a kind of automatic drying so there is no need for staff on duty during the drying process.

5. High-quality high frequency vacuum wood dryer machine

Our high-frequency vacuum wood dryer machine is made of stainless steel to avoid corrosion and rust.

6. Killing Insects & eggs

Insects (eggs) and fungus will be killed during the drying process thoroughly, there will be no need for chemical treatments anymore.

Our kiln also adopts vacuum dehydration technology. 
The stainless steel vacuum pump can make the vacuum oven reach -0.093Mpa condition. 
The vacuum condition is to let let water vaporized in low temperature below 55 ℃,At the same time, vacuum can also suck the wood moisture out. 
The machine cooling system will separate the hot air and hot water out, then cool them and release them out.  
Wood is drying under a vacuum and wet condition at low temperature. 
That will ensure wood is no cracks and keep the wood nature color.
High frequency vacuum dry kiln is the best choice to thick table top, veneer, thick slab, expensive wood, hardwood, veneer, beam and etc.

Main components of vacuum kiln

Main body of vacuum kiln

The reason why our vacuum kiln cabinet is square 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.

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.

Installation Video of Wood Drying Kiln

It’s well known that from 2020 to 2023, global circumstances hindered on-site installations, prompting us to assist customers via instructional videos, live video and manuals. Clear component labeling facilitated the process, proving effective.

With 3 years of online installation guidance and over 10 years of on-site wood drying machine installations, our technicians have become highly proficient. And now we continue to offer on-site installation services worldwide, complemented by 24/7 online support from our technical staff for free consultations and training.

Helping you solve kiln-dried wood problems

SW-10.0III-High-Frequency-Vacuum-Wood-Dryer2.jpg
Drying without Warping and cracking

Compared to conventional steam kilns, high frequency heating directly heats wood inside and out simultaneously. Vacuum technology enables drying in moist conditions at low temperatures, preventing cracks and preserving natural wood color. Our machine features a top hydraulic system providing 6 tons of pressure throughout the drying process, preventing warping.

Accelerating Drying Time, Enhancing Drying Quality

In conventional drying kilns, the preparation is lengthy, operation complex, and the wood drying quality is easily influenced by the operation of workers. Shuowei kilns, with their simple integrated design and user-friendly control board, offer easy installation and stable, reliable drying results with minimal operator intervention.

A wood dryer can help you quickly drain excess moisture from the wood, making your money flow more smoothly

Shuowei’s wood drying kiln is a very environmentally friendly product, don’t need to burn a boiler, it only needs electricity to run

The air in the furnace is evacuated by a vacuum pump, and the wood is dried in vacuum mode, so that the dried wood will not have any defects

The dehumidification kiln can only remove the water vapor on the surface of the wood, so the dehumidification kiln cannot dry the wood into the wood you want

High-frequency vacuum kiln is currently the fastest drying kiln on the market. Its drying environment is to dry wood by high-frequency generator under vacuum.
High Frequency: 6.78Mhz Wavelength: 10-100m
