1. Greatly Reduced Drying Time
The surface and interior of wood is evenly heated by high
frequency energy. In this drying method, the surface
temperature of the wood lowers due to the release of heat
and the evaporation of moisture, and thus the interior
has a higher temperature than the surface. The vapor
pressure difference caused by this surface and the
interior temperature difference makes the interior
moisture to move towards the surface. For this reason,
the drying time of the wood is cut to one-third the time
of the hot air drying method, and to one-tenth in the
case of wood with good permiability.

2. Lower Temperature Drying (Constant Quality)
Wood drying at low temperature highly humid environment
enable complete free from cracks & distortions as
well as retain its hue & luster.
|
3. Easy Drying of Thick Wood & Wood with high Moisture Content
High Frequency interior heating heats & dries the
interior of thick wood simultaneously. The high frequency
easily absorbs moisture, and unevenness of moisture
content at the initial stage will be balanced out in the
drying process.
|
4. No Need for Stiffener Piling
Time consuming stiffener piling is unnecessary for high
frequency heating. The inside of the vacuum chamber can
be efficiently used, and wood which can easily warp,
veneer, etc. can be dried while pressure is applied to
flatten it.
|
5. Prevention of Oozing Resin (Quality improvement)
High frequency pressure reduced drying dissipates and
stiffens resin in wood and prevents it from oozing out.
Therefore, natura1 oils within the wood are maintained,
and b good
luster quality wood can be produced.

6. Automatic Operation Under Optimum Heating Conditions
The High ElecDryer automatically conducts efficient operation, by controlling the high frequency output under
optimum conditions while measuring the drying condition
of wood continuously in accordance with the drying
progress.

7. Easy Operation
Just push the cart loaded with wood into the tank, close the tank, and press the start button. Operation is automatically performed in accordance to the preset
program.
