The possibility of drying in superheated steam or superheat4 solvent vapour has knru lised for a long time but praclised very Linle. Rccenc advanwhave led to predictions of npid gmwch of steam-drying applications. Most of these exhibit remarkable energy-savings over conventional plant and reductions in cost which make atwctivc the installatian of steamdrying plant even wichout “Greenhouse” considerations. Given chis pw~phot ential, it is ersential to hink about those aspecrs of scale-up particular to steam-drying. This paper looks at chc variery of potential steam-drying plant and related scale-up problems. while recognising chat each parricuiar, cygeo f plant requires more individual consideration dmc an be addressed in this brief Ppa.
