Superheated Steam Drying

• Higher drying rates possible in both CRP and FRP depending on steam temperature (above the so-called inversion temperature SSD is faster than air drying)-not a decisive factor for selection! • Toxic or organic liquids can be recovered easily- by condensation (e g wood drying) SOME ADVANTAGES OF SSD • Casehardened skin is unlikely to form in SSD-mechanism not known- product dependent
