The material is exposed in the container at a pressure of at least 20 bar and at a temperature of at least 200°C. The material is processed with the cooking liquor in the container and the material is moved with at least one ring counter compression, located on the inner surface of the container when movement of the material down through the container. The material is mixed in the container and the processed material is released from the lower outlet of the container.
EFFECT: container for chemical treatment has a relatively simple design that enables to process a large volume of light, bulk cellulosic material.
