Abstract
T
he thin layer drying behaviour of acorns was investigated at three oven temperatures (60, 70
and 80 °C). The drying kinetic was fitted and modelled using di ff e rent mathematical drying
models. The use of First Order (FO) and Pseudo First Order (PFO) was proposed and
estimated for describe the moisture content evolution of acorns as a function of time.
According the coefficient of determination R² ), the root m ea n square error ( RMSE ) and the
sum mean of square error ( ² ), t he best fit was given by the L ogarithmic model. A good fit
R² > 0.9942; RMSE < 2.238 and ² < 6.014) was shown by FO and PFO indicating their
aptitude to describe the thin layer drying kineti c o f acorns E ffective moisture diffusivity
increased from 4.016 10 8 to 1.244 10 7 m² s 1 with the rice of drying tem perature. T he
elimination of water from the acorns requires an activation energy of about 55 kJ mol
