Product Description Working principle of high-frequency vacuum dryer:High frequency vacuum drying is a combined drying method of
high-frequency medium heating and vacuum low-temperature drying,
which is a fast and almost waste free drying method, especially
suitable for drying hardwood and heavy wood. High frequency heating: Also known as high-frequency medium heating, it converts a regular
380V AC power supply into a high-frequency electromagnetic field
after boosting and rectifying it. High frequency heating can be
achieved through related supporting equipment with anode and
cathode plates. High frequency heating is penetration heating, where the moisture
in the electric field is uniformly heated. The parts with more
moisture absorb more high-frequency electric fields, while the
parts with less moisture only absorb a small amount of
high-frequency electric fields. This effectively utilizes the
high-frequency output power. However, media such as wood or fiber,
due to their lack of polarity, do not absorb electric fields, and
high-frequency power is basically used without waste, saving energy
consumption and reducing drying costs. Vacuum state mainly utilizes the lower boiling point of water in
vacuum state, which accelerates the evaporation rate and increases
the gradient of moisture content on the surface of wood. During the
drying process, on the one hand, surface moisture evaporates into
the surrounding air, and on the other hand, internal moisture
continuously moves towards the surface, thus accelerating the
drying rate at lower temperatures, ensuring the drying quality of
wood. The vacuum state is a negative pressure state that has a
certain water absorption effect, which is exactly similar to the
high-frequency pressure gradient and accelerates the discharge of
moisture from the wood core. In addition, under low pressure
conditions, the oxygen in the drying medium causes less
discoloration of the material due to thermal and oxidation effects,
which can basically maintain the natural color of precious wood. Based on the above characteristics, the application of
high-frequency vacuum drying in wood drying has become a scientific
and environmentally friendly drying method, especially suitable for
drying hardwood with a large cross-section. Characteristic1, The use of high-frequency heating solves the problem of rapid
heating and drying of wood. 2, The wood is heated both inside and
outside, evenly and of good quality, which can maintain the natural
color of the wood. 3, The use of vacuum water absorption reduces
the temperature of the wood drying process, causing the wood to
vaporize at low temperatures, making it less prone to cracking and
improving the dehydration rate of the wood. 4, Environmentally
friendly and non polluting. 5, High frequency waves can kill
insects and bacteria hidden inside the board, while shortening the
drying cycle and further ensuring the quality of wood drying.
Especially suitable for drying thick, hard, large section square
wood (conventional drying methods require a long time), precious
rosewood wood such as rosewood, chicken wing wood, yellow pear,
etc., as well as drying wooden floors. At the same time, secondary
drying of small batches and expedited wood after moisture regain is
also used. Configuration1. Intelligent human-machine interface automatic control, control
personnel only need to set basic parameters such as drying process,
initial moisture content, and required final moisture content, and
the drying process is all automatically controlled by the program.
2. High frequency automatic tuning, without the need for personnel
adjustment, the fault detection system can detect the working
status of the equipment at any time. If there is a fault, the
equipment will be powered off and an alarm will be given and fault
information will be prompted. 3. The humidity detection adopts
online real-time monitoring of moisture content,? The moisture
content of wood can be detected at any time to ensure the accuracy
of moisture content monitoring. 4. The temperature adopts a fiber
optic temperature detection device, which is accurate and not
affected by high-frequency interference. Temperature detection is
only used to ensure the drying effect, avoiding the problem of
serious data errors in the detection of ordinary metal probes in
the electric field.
