Description

Technical field:

[0001] The invention relates to a wood heat treatment device and method, in particular to a treatment equipment and a treatment method for increasing the wood heat treatment rate, and belongs to the field of wood heat treatment. Background technique

[0002] Wood is a renewable, environmentally friendly and recyclable material with excellent natural properties. However, because of its special biological structure, it must undergo certain processing before it can be used. High-temperature heat treatment of wood technology does not add any chemicals, which can improve and improve the quality of fast-growing plantation wood, and replace some high-quality natural forest wood.

[0003] In order to improve the weather resistance, dimensional stability and decay resistance of wood. Patent 201310604960.4 provides a high-temperature heat treatment process for fast-growing plantation eucalyptus wood. This invention pre-treats fast-growing plantation eucalyptus; boils...
