1. Brief introduction
High frequency is also called Radio frequency, it applies dielectic
heating with 6.78MHz frequency. It can penetrate wood deeply and
dry the wood moisture from core to the surface uniformly. It also
equips vacuum together. The drying effects is much better. It is
suitable for all kinds of wood, especially for large wood beams,
hard wood, rare wood as well as veneers drying
Since year 1993, JIYUAN' engineers devote themselves to High
frequency woodworking machinery developing and manufacturing.
Year 2002, we were awarded ISO 9001:2000 international quality
system certification and manufacture the machine strictly according
Year 2005, JIYUAN cooperated with several famous Forestry
universities and developed our High frequency vacuum dryer.
At the same year, JIYUAN was awarded the director unit of CHINA
NATIONAL FORESTRY MACHINERY ASSOCIATION (CNFMA)
In high frequency woodworking machinery field, JIYUAN is the only
director unit. Because of qualified products and excellent after
In year 2012, we bacome the director unit of CHINA WOOD DRYING
PROFESSIONAL COMMITTEE, CHINA NATIONAL FOREST PORDUCT INDUSTRY
2. Features of HF vacuum dryer
1) PLC automatical control with touch screen interface. Fault
2) Machine passed REGULATIONS FOR ELECTROMAGNETIC RADIATION
PROTECTION. Safe for operators.
3) High frequency dielectric heating. Drying wood more than ten
times faster and more unfirmly than traditional kiln.
4) Vacuum minus pressure drying. Much safter for wood. There is no
wood crack, color change problems.
5) With hydraulic system and press. During the drying process,
hydraulic system will give pressure on wood. After drying, wood
will not bend.
6) Integrated design of cooling system. Save floor area and more
7) Humanized and safe design on tank door and feeding cart.It
doesn't need additional rail outside and easy to load wood, open
and close tank door.
8) Advanced temperature inspection system. Test the wood
temperature correctly and will not disturbed by High frequency.
9) Advanced Wood weight measurement system. It can test the wood
weight at any time. Then can show the wood moisture at present.
10) Worm and bacteria killing.
11) Does not need boiler. No polution.
