The present invention relates to a new type of arrangement to facilitate the processing of a pulp when discharging it from a pulp tank. The method and the arrangement according to the invention are especially suitable for use in emptying digesters and tanks in the cellulose industry. The arrangement according to the present invention is characterised in that in the bottom part and/or outlet duct of the tank a helical control element, which guides the liquid tangentially between the surface and the pulp in order to reduce friction, has been arranged in the liquid phase between the surface of the tank and perforated plate. <IMAGE>
