Drying has been defined as the process whereby moisture is vaporized from a material and is swept away from the surface, sometimes under vacuum, but normally by means of carrier gas which passes through or over the material [Keey (1992)]. Commonly, drying is conceived as the removal of water into a hot airstream, but …
WebEquation (11.168) is used to estimate Δ t, the time required to dry solids from an initial moisture content of X0 to a final moisture content of X1 when the drying rate is constant. From the definition of drying rate in Eq.
