Wood secondary drying equipment

Product Introduction:

Most wood processing enterprises now use dried wood, with many manufacturers assuming the wood is dry and proceeding directly to production. However, issues like cracking, warping, and paint bubbling have arisen, which are generally not expected. The root cause is often uneven moisture content. Despite various attempts like carbonization, hardening, and wax injection, the problem is not fundamentally resolved; what issue must be tackled at its source?

We strictly control the raw material intake. Wood that has been dried is not considered dried wood. It must be tested for compliance before entering the workshop, and if it does not meet standards, it must be dried a second time.

2. Strictly control semi-finished products; absorb moisture from the air during the production process, especially in humid air, during the summer months with high humidity, the plum rain season, where wood tends to absorb moisture heavily, leading to high moisture content. Additionally, during processing, the gaps between boards are glued with adhesive containing 40% moisture, which can cause the boards to swell, burst, or exhibit wavy patterns. Therefore, semi-finished products must be preserved before sanding and painting.

3. To cater to the market, our company has developed two types of secondary drying equipment. One is an intelligent far-infrared electric energy drying box, and the other is a vacuum high-frequency drying equipment.

Advantages:

A. Multi-band automatic temperature control, high-temperature alarm, humidification, dehumidification, timer on/off.

B. Fast heating, even heat distribution, low heat loss, easy to assemble/disassemble, and convenient for movement.

C. Dual-purpose for oil (gas) and electricity; uses low-voltage electricity at night with low costs, burns oil (gas) during the day also at low costs; environmentally friendly and practical; computer numerical control for labor-saving and efficiency.

D. Air-source heat pumps are safe and environmentally friendly, absorbing 70% of the heat energy from the air, several times more efficient than traditional methods.

E. Vacuum high-frequency secondary drying equipment is particularly suitable for thick, hard, large-section square timbers (which require a long time with conventional drying methods), as well as valuable woods such as rosewood, huanghuali, and chicken wing wood.
