China Making HF Vacuum Woodworking Equipment for Lumber Drying Fast

1.Product Description
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 each batch.

3.Main Features
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 .

6)Envirnoment friendly
HF heating doesn't need boiler.There is no dust,no fog,no pollution.DAXIN's products accord with national standard of radiation.

4.Main parts of HF Vacuum Heating Wood drying Machine

1).High strength steel structural oven body.
   This makes the whole machine stronger and more leak-proof of vacuum.
2).High frequency generator
  This is the core of this machine, all procedures and main technology are inside,
  Including PLC,electric valve etc..
3).Cooling tower
  This part is mainly used in hot weather, the main usage is to cool the internal
  temperature, guarantee the drying speed and quality. 
4).Timber cart
  We have both full-auto feeding mode and manual feeding model, but the full-auto is
  only used on 8/10/12/15cbm models, because the smaller doesn't need this, the
  loading quantity is enough to be push into the oven by workers.
5).Stainless condenser
  This parts are also to reduce the internal temperature when drying, it will let the
  steam change into water droplet, to guarantee the drying speed and quality.
6).Pressure system
  We have both hydraulic and pneumatic, that means common oil pressure system
  and air pressure system, they are to prevent the wood becoming bend and crack.
7).Perforated aluminum plate and wooden bar
  The perforated aluminum and corpper strips promote electronic cycle to improve the speed of heating,
  and these two parts are to separate by wood bar to dissipating heat quickly, guarantee the
  drying speed. 
8.Final moisture measurement

the moisture can be reduced from 60% to 8% even 6%, only need to 3- 7 days each batch.
