kiln for wood drying
When dried wood is used constructional, whether as a building structural support or in any wood working objects, it will absorb or expel moisture until it is in equilibrium with its surroundings. Equilibration (usually drying) causes unequal shrinkage in the wood, and can cause damage to the wood if equilibration occurs too rapidly. The equilibration must be controlled to prevent damage to the wood. That is why we need drying kiln in order to prevent any casualties in our wood, thus saving money and effort for any person involved.
Shuowei releases variety of wood kiln products that is relevant and appropriate to your wood drying, ensuring your convenience and comfort in every procedure you’re making. We offer this series, kindly check below.

Reasons for splits and cracks
The common difficulty experienced in the drying of timber is the tendency of its outer layers to dry out too fast than the inner ones. If these layers are allowed to dry much below the fibre saturation point while the interior is still saturated, stresses are set up because the shrinkage of the outer layers is restricted by the wet interior. Rupture in the wood tissues occurs, and consequently splits and cracks occur if these stresses across the grain exceed the strength across the grain.
How does are product prevent these damages?
The successful control of drying defects in a drying process consists in maintaining a balance between the rate of evaporation of moisture from the surface and the rate of outward movement of moisture from the interior of the wood. The way in which drying can be controlled will now be explained. One of the most successful ways of wood drying or seasoning would be kiln drying, where the wood is placed into a kiln compartment in stacks and dried by steaming, and releasing the steam slowly.
Types of wood our products can dry
Wood is divided into two kinds: softwoods, from coniferous trees, and hardwoods, from broad-leaved trees. Softwoods are lighter and generally simple in structure, whereas hardwoods are harder and more complex. Although softwood are faster and easier to dry, our product can help you to dry hardwood with no hassle and effortless.
Shuowei Advantage
Shuowei was established in 1990, dedicated to the research and development, and innovation of wood drying kilns. After 32 years of development, it has produced the wood drying kiln with the fastest drying speed and no defects in the dried wood – high frequency vacuum wood drying kiln.
Shuowei has been devoted deep into the vacuum wood drying field for over 30 year, we pay much attention on improving the operation and developing the designs. Shuowei focused on easier faster and higher quality wood drying solutions. Shuowei drying kiln can quickly help you solve the problem of wood drying and ensure that the wood does not crack or deform.
How the product works
High-frequency heat can penetrate the wood deeply and dry wood them from inner part up to it’s outer surfaces, envenly. Thick and big wood can be dry well using this kilns also. 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 thick wood can be dried by our high-frequency vacuum wood dryer machine with uniform moisture content within two weeks.
drying effect
High frequency is kind of directly heating, In the electricity filed, wood will be heated both inside and outside at the same time, the vacuum technology allows the wood drying process is under an vacuum wet conditions and at a low temperature, which will ensure there is no cracks and keep the wood to be nature color.
Different parts of drying kilns
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 isthe 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 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 in the wood.
Hydraulic 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. This hydraulic device can provide 6-8 tons of pressure.
Motor Drive Timber Cart
Automatic feeding device, when we investigated the wood drying market, we found that it is very laborious and inconvenient for workers to load and unload wood. Our team has developed an automatic feeding device, which can greatly reduce labor.
Outer Shell
This is the outer part of the drying kiln. It act as the main protector and the skin of the body of the machine. This is usually stainless and corrosion-proof as it serves for longer life.
pneumatic Valve Stainless Stell pipes
This is a type of power-operated pipe valve that uses air pressure to perform a function. As air pressure is increased, the compressed air starts to push against the piston or diaphragm walls which causes the valve to actuate.

Bottom FAQ
Before finding a proper type, the main factors to consider are as below
- Wood species (walnut,ash, acacia, rosewood,oak,pine,teak, Africa hardwood etc.)
- Thickness in mm of your wood slab Initial moisture and target moisture
The above data will decide the drying time of per batch. For example, if you plan to dry 50 CBM ash slab with thickness of 100mm per month and initial moisture is 30-40%. According to the data, it will take 5 days to reach 8% MC. So In a month, you can finish 6 wood drying cycles.Then we could know the net capacity of high frequency vacuum wood dry kiln should be 8 CBM (50CBM/month ÷ 6 monthly cycles = 8.3cbm), Based on this, it is easy to find that SW-8.0III is suitable for you. The capacity of SW-8.0III model is 8.64cbm
Compared with the air seasoning and conventional kiln drying, high frequency vacuum wood dryer kiln has greatly shorten the drying circle, you do not need wait years or months to get quality dried wood any more. The average drying time is 4-15 days to finish whole dry process.
The warranty of Shuowei high frequency vacuum wood dryer kiln is one year since received the dryer. If any part damaged because of non-human factors，we will send new parts for replacement free.
This kiln is not prone to fire. why? Because since the inside of the wood dryer kiln is a vacuum condition and has no oxygen, it won’t catch a fire even if it is sparked.
The vacuum chamber is make of stainless steel, so it is very tough, and the daily maintenance work is just some cleaning after finishing one drying cycle. The main electronic components are all using top brand (like Schneider) and the high frequency generator is with a self-protect programs, so the maintain costs could be almost ignored.
After you place the order, we need 25 days to finish the production and testing of the high frequency vacuum wood dryer kiln. and then we will arrange the latest shipment. If you have plan to purchase this high frequency vacuum wood dryer kiln from us, please contact us ahead of time, we do not have many ready stocks for such machines for requirements varies from different clients.
Kiln drying your own wood at home can be a great way to sustainably harvest the materials around you, and dry it fast enough to build furniture with. If furniture is made with wood that is too wet, it will continue to dry and crack, possibly ruining the piece.
With air-dried wood there are no internal tensions baked into the wood. Kiln dried wood can be more fragile and break off easily. It can chip easily especially when working with hand tools, spokeshave or powered knife. Kiln dried wood often loses about 20% of its color, even when it is not steamed.
Modern dry kilns allow tight control of air flow, temperature and humidity so that all the timber dries uniformly and to the precise moisture content required. Kiln drying often means a more uniform product and the problems often associated with poorly air-dried timber are avoided.
A conventional kiln uses steam flow into the kiln through pipes and radiates heat into the kiln’s atmosphere. Water content of the wood is converted into vapor by evaporation and discharged from the kiln with the hot air.
