The industrial production of "carbonized wood" originated in Europe in the 1990s. Its typical production processes include: Thermal-wood, Retification, PLATO-process and oil-Treatment, etc. Carbonized wood production equipment at home and abroad can be divided into two categories: kiln type and tank type. Each has its own characteristics, but it has common requirements, and its process also has common characteristics.

The discoloration of wood, simply put, is the color change on its surface due to the action of the environment (sunlight, oxygen, moisture, temperature) and microorganisms (fungi).

Compared with the conventional drying, vacuum wood drying kiln can be achieved under the condition of low temperature rapid drying of wood, and ensure the quality of wood drying, largely avoid the generation of wood shrinkage defects.Through expert analysis to explore the discovery, cypress, for example, above the fiber saturation point, vacuum drying rate for conventional dry 2.34 ~ 2.88 times;While in the FSP, is 2.90 ~ 4.14 times.
