The HF vacuum wood drying machine is result of design combining high frequency medium heating technology and vacuum cryogenic dehydration technology,greatly reduceed drying time and avoid high temperature damage of wood.It apply to all the kinds wood, such as oak ,verawood ,rose wood , the moisture can be reduced from 60% to 8% even 6%, only need to 3- 7 days every drying cycle.
1. To dry all kinds of wood in board or column type, slab type, cant type, timber type etc..
2. To dry all kinds of wood in veneer type.
3. To dry all kinds of wood for no bending , no cracking , no color changing .
|Max Length of Wood||3m||4m||5m||6m||7m||8m|
|Vacuum oven drying temperature not more 90 degree|
|Moisture||From 90%to 6%, can be setting according to your requirements .|
|Drying time||2-7 days|
|Application||Apply for all the hardwood piecise|
1) Fast speed and high efficiency
When HF starts,the molecules in the dielectric material will be polarized in very short time and heated.HF power only heat polar molecules.It will not heat dielectric material.HF heating is 3-5 times faster than hot steam.So it can save the power and improve the efficiency.
2) Uniform heating
High frequency heating is dielectric heating.It forms electric filed with positive and negative pole.HF power can penetrate material deeply.The waster or glue molecules in the material will get heated themselves by friction among molecules.In this way,they get heated from the core material,much more uniformly. 3) Good applicability
High frequency heating can heat kinds of thickness material,such as 2-3mm venner surface lamination,1000mm thick engineered wood gluing.And different frquency can meet different material requirement.13.56MHZ is suitable for PVC heating and gluing 27.12MHZ is good for line production .
4) Strong controllability
High frequency heating is easy control and suitable for automatic production.Take HF edge gluer for example,HF can equip well with hydraulic system,electrical system can finish the whole process together.It can also well cooperate with last procedure.
5) No damage of wood
In the vacuum environment, moisture can evaporate at lower temperatures ,so vacuum cryogenic dehydration technology avoid high temperature to damage wood .
HF heating doesn't need boiler.There is no dust,no fog,no pollution.DAXIN's products accord with national standard of radiation.
1).It is new drying method. (Dielectric heating)
Steam and normal vacuum dryer (hot plate) is conductive heating. They dry the wood little by little from outside to inside.
High frequency is dielectric heating. HF wave can penetrate the thick wood and dry it uniformly. Even the core of wood temperature is heater than surface.
Vacuum condition: It is minus pressure, safe.
The wood moisture can vaporized in low temperature.
Then vapor will be pump out automatically. So HF vacuum dryer is faster, more uniform, no bending and no crack caused by non-uniform.
2). No need boiler; No need hot plate (no hot water)
The power supply of HF vacuum dryer is electricity. It does not need boiler, save the human resource and protect the Environment.
3). Worm killing.
High frequency can kill the worm and bacteria. It does not need special chemical treatment.
5.Comparative With Tranditional Wood Drying Kilns
|Item||HF Wood Drying Machine||Traditional Fire Kiln Dryer|
|Heating method||High Frequency||Hot water or steam heating|
|Drying speed||Fast(1-7days in average)||Slow(20-45days in average)|
|Heating||Uniform heating||Outside high, Inside low|
|After-drying quality||No bend&crack, No color changing||Maybe some damage|
|Life span||Long and guaranteed||short|
|Late investment||Very low||High|
|Main feature||Small,fast, flexible||Big, slow,backward|
6.Comparative With Microwave Wood Drying
|Item||High frequency vacuum||Microwave vacuum|
|Heating method||High frequency||microwave|
|Diathermy way||through heating||The internal and external heating|
|Heating area||uniformity||Outside high,inside low temperature|
|Drying temperature||Can be high to low||high|
|Drying quality||Perfect||Maybe some damage|
|Microwave vacuum wavelength 600-900 MHZ, and 600-700 MHZ can be used, the rest is radiation. Usually below 30 MHZ , no provisions of the state.|
Our factory high frequency vacuum wavelength is 6.78 MHZ .

1.What is the yearly maintenance cost and what are the parts that need to change?
There is no yearly maintenance cost, the machine not break usually if you use it normally. If there
were any parts broken within 1 year, and it is caused not by person, we will supply the parts freely.
2.Does all the system has top pressure beam in the chamber? What is the tonnage or pressure bar being used.
We have the press system for all machine, We have hydraulic and air press types. This part will press the wood to prevent the deformation of wood. The weight is 3 tons, this also can do as your requirment.
3.What will be the variation of MC in the chamber +/-1% ,2%, 3% or more after drying?
For the different moisture, the final will be same, because it is smart controlled, when the machine start to work, it will find the high MC wood firstly and to dry it, once the MC are same, all the timber will be dryied together, finally it will be same after drying.
4.Could you provide those customers or to whom you have sold your machines in the domestic and in the world?
Pls see our New Zealand customer info. We also exported to Thailand, Japan, Viet Nam, Uganda, Iran and so on countries. Now our Iran customer is in factory to test the machine.
