Zusammenfassung:	A screen used in the production of cellulose pulp may be mounted in a digester to minimize traditional screen problems (including clogging) without introducing new problems. The screen comprises a screen plate having a plurality of slots formed in it with an inclination angle, which is 30-60° with respect to the bottom edge of the screen plate. The screen plate may comprise a plurality of parallel screen bars side-by-side, or an integral metal plate with slots formed in it. The slots have a width between 1-5 (e.g. 2-4) millimeters and a spacing between them of 3-9 millimeters.
