Process for obtaining beet pulp of high dry-solids content from a sugar extraction process by mechanically pressing the pulp, mixing salts of polyvalent cations, an acid or both with the pressed pulp, further pressing the admixture and thermally drying the admixture. The salts of the polyvalent cations are preferably calcium chloride, aluminum chloride and ferric chloride and are added in an amount of from 0.5 to 10%, preferably from 1.5 to 4%, relative to the pulp dry-solids content. The liquid from the second pressing can be concentrated by evaporation and at least part can be recycled to produce the initial solution of the salts. The remainder of the concentrated liquid can be added to the pressed admixture before or after drying to further increase the dry-solids content.
