A process for treating lignocellulosic material, such as wood for example, the process including the steps of: a) providing lignocellulosic material; b) evaluating parameters of the lignocellulosic material; c) preparing the lignocellulosic material; d) heating the lignocellulosic material in a treatment chamber following a given profile based on parameters of the lignocellulosic material; e) stabilizing the lignocellulosic material; and f) cooling down the lignocellulosic material. The process enables to improve the quality of the wood being treated, while ensuring a greater repeatability and uniformity of coloring results, and overcoming drawbacks associated with conventional torrefaction methods.
