Abstract

This paper deals with the application of inverse concepts in drying. The objective of the paper is estimation of the moisture diffusivity of a drying body by using only temperature measurements. Potato and apple slices have been chosen as representative drying bodies with significant shrinkage effects. A mathematical model of the drying process of shrinking bodies has been applied. The Levenberg-Marquardt method and a hybrid optimization method of minimization of the least-squares norm were used to solve the present parameter estimation problem.
