DIFFUSIONAL PROCESS IN THE DRYING OF TAPIOCA ROOT

ABSTRACT— Experimental results obtained in the through‐circulation drying of tapioca root slices were analyzed to obtain the effective diffusivity in the material. Results are in good agreement with the theoretical solution which assumes the diffusivity to be constant; however, for a better comparis...

Results are in good agreement with the theoretical solution which assumes the diffusivity to be constant; however, for a better comparison, a model with variable diffusivity appears to be necessary. It can also be seen that as temperature increases, the constant diffusivity model represents closely the experimental results. The assumption that water migrates within tapioca root by a process of liquid diffusion is also confirmed by the Arrhenius type temperature dependence of calculated values of the effective diffusivity.
