The working principle of the high frequency wood vacuum dryer is as follows:

1. Vacuum: First, the wood to be dried is placed in a vacuum chamber. In a vacuum environment, the oxygen on the surface and inside of the wood is removed, which can effectively prevent the wood from being susceptible to oxidative deterioration during the drying process.

2. High-frequency electric field: Then, a high-frequency electric field is generated in the vacuum chamber. This high-frequency electric field can quickly excite the water molecules on the surface and inside of the wood, causing it to vibrate and rub violently, and quickly convert it into heat energy.

3. Moisture Drainage: Due to the increase in temperature inside the wood, the water molecules gradually diffuse outward from the inside of the wood and drain out. Since the wood is in a vacuum state, the moisture is easily and quickly drained.

4. Restoration of pressure: After the moisture inside the wood has been expelled, the vacuum chamber needs to be restored to pressure. At this time, the moisture vapor in the vacuum chamber will be drawn out, and condensed into liquid through the condenser, and finally, the moisture will be drained away.

Through such a series of processes, the high-frequency wood vacuum dryer can complete the drying of wood in a very short period of time, keeping its original color and texture. Compared with traditional steam-heated dryers, it saves a lot of time and energy, and at the same time avoids problems such as wood deformation and surface cracking caused by overheating.

Actually, the radio frequency wood vacuum dryer has been widely used at home and abroad, which has greatly promoted the development of the wood processing industry. In the future, with the continuous advancement of science and technology, this new type of wood drying equipment will continue to improve and develop, bringing more convenience and benefits to people.
