Water is sprayed on to theoutside of the cylinder, and a fixed sciaper isprovided inside to lift up the crystals as thecylinder rotates. The ci-ystals and mother liquorare discharged from the open lower end of thecylinder into a shoot, which guides them to centri-fugals or other di-ying apparatus.—W. H. O.
