Abstract
The invention relates to a method for treating biomass (). In a step (S) of the method, the biomass () and an amount of water () is fed into a first reactor unit () such that the biomass () is impregnated using the amount of water () while the biomass () is transferred through the first reactor unit () by a conveyor means (). In another step (S), the impregnated biomass () is transferred from the first reactor unit () to a separation unit () in which at least a part () of the amount of water () used for impregnation can be separated from the impregnated biomass (). In another step (S), the impregnated biomass () is transferred from the separation unit () into a second reactor unit () in which the impregnated biomass () is subjected to a predetermined pressure (S). The invention further relates to the use of the method for treating non-wood material as well as to a device for treating biomass ().
