Summary: | A rapid method is described for analysing and predicting the performance of static-bed and cross-flow driers. The first step of the procedure uses a graphical construction to establish the effective adiabatic equilibrium curves. These can be used to carry out a broad qualitative analysis of moisture transfer operations in the absence of kinetic data. In a subsequent step, known solutions for isothermal non-equilibrium sorption are applied to these curves to derive moisture and temperature profiles and histories, air flow requirements and other design parameters of interest. No numerical solutions of the relevant model equations are required and the method is quite generally valid for any arbitrary form of moisture isotherms. Sample illustrations are given for deep-bed and cross-flow drying operations. |
