APPARATUS AND METHOD FOR THE HEAT TREATMENT OF LIGNOCELLULOSIC MATERIAL
摘要
There is provided an apparatus and a method for heat treatment of lignocellulosic material. The apparatus comprises a treatment chamber and devices for circulating and recovering gases from the treatment chamber such as to provide a uniform temperature within the chamber and allow efficient drying of the material. This is achieved by injecting and recovering the gases from at least two sides of the treatment chamber.
