Abstract
The study estimates moisture diffusivity and other thermophysical properties of potato slices dried using far-infrared radiation under vacuum. A mathematical model for drying shrinking bodies was used for the direct problem, while the inverse problem was solved using the Levenberg–Marquardt method. The influence of vacuum pressure, heater temperature, sample dimensions, and drying time was analysed using the D-optimum criterion. The estimated moisture diffusivity ranged from 5.14×10−85.14 times 10^{-8} to 5.01×10−9 m2/s5.01 times 10^{-9},text{m}^2/text{s}. Experimental temperature and moisture changes were compared with the numerically calculated results.
