Drying Equipment for Second-Grade Wood

Product Description:

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 such as carbonization, hardening, and wax injection, the problem is not fundamentally resolved; what issues must be tackled at their source?

We strictly control the incoming material quality. 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 re-dried.

2. Strictly control semi-finished products; absorb moisture from the air during the production process, especially in humid air, during summer months with high humidity and the plum rain season, where wood tends to absorb more moisture, and the moisture content is higher. Additionally, during the processing, adhesive with 40% moisture content is used to bond the gaps in the boards, which can lead to phenomena such as protrusions, explosions, and wavy patterns. Therefore, semi-finished products must be conditioned 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, scheduled on/off.

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

C. Dual-purpose oil (gas) and electric, using flat voltage at night with low cost, burning oil (gas) during the day with low cost, environmentally friendly and practical, CNC controlled, labor-saving, and efficient.

D. The air-source heat pump is safe and environmentally friendly, absorbing heat energy from the air to save up to 70%, 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.
