Recently, the high-frequency vacuum wood modification and drying integrated equipment independently developed by Shandong Junxu Heavy Industry (Group) Co., Ltd. has been successfully installed, debugged, and put into operation at multiple domestic hardwood processing enterprises. The equipment integrates vacuum drying and modification treatment, adopting combined technology of high-frequency dielectric heating and vacuum low-temperature drying. It is specifically designed for drying and modifying large-section hardwood species and precious woods (such as rosewood, wenge, and huanghuali).

Technical Features

High-frequency vacuum drying technology selectively heats the moisture inside the wood through a high-frequency electromagnetic field, achieving simultaneous internal and external heating and uniform heat distribution. This effectively avoids cracking, warping, and other issues caused by temperature gradients in traditional drying methods. Meanwhile, the vacuum state lowers the boiling point of water, allowing rapid dehydration at lower temperatures, which helps preserve the natural color and physical properties of the wood.

The equipment features an intelligent human-machine interface for automatic control. Operators only need to set drying parameters such as process curve, initial moisture content, and target final moisture content; the entire drying process is automatically completed by the program. The equipment is also equipped with an online real-time moisture content monitoring system and a fiber-optic temperature detection device, which is immune to high-frequency interference, ensuring measurement accuracy.

Application Fields

The equipment is particularly suitable for the following applications:

• Drying and modification of precious rosewood furniture materials

• Rapid drying of thick, hard, and large-section timber

• Small-batch, urgent, and re-drying of rewetted wood

• Processing of wood flooring and high-end decorative materials
