Abstract: A method for preparing a pressed article comprises providing a first and a second pressing ram in a compression chamber; supplying biomass particles in the chamber closing the chamber; extending the first pressing ram; displacing the biomass particles with the first pressing ram towards the second pressing ram; detecting abutment of the biomass particles on the second pressing ram; applying pressure to the biomass particles with the first pressing ram and with the second pressing ram detecting a pressure applied to match a predetermined pressure and continuing to extend the first and the second pressing ram until a predetermined time at the matched compression pressure has elapsed; stopping the extension of the second pressing ram when a predetermined extension length is reached; continuing to extend the first pressing ram until a predetermined additional time has elapsed after the stopping; ejecting a pressed article.
