ABSTRACT = {This study determined the most appropriate thin layer drying model, the effective moisture diffusivity and the activation energy of moisture within 
Ganoderma lucidum in radio frequency (RF) assisted heat pump drying method. The thin layer drying experiments were conducted with input drying 
parameters such as: drying temperature of 40, 45 and 50°C and RF power of 0.65, 1.3 and 1.95 kW. In order to select a suitable form of drying curve, 
seven different thin layer drying models (Lewis, Page, Modified Page, Henderson and Pabis, Verma, Midilli, and Wang and Singh) were fitted to the 
experimental data. The Verma model was the most adequate model for describing the thin layer drying of Ganoderma lucidum. The average effective 
moisture diffusivity values varied from 2.34×10<sup>-9</sup> to 3.54×10<sup>-9</sup> m<sup>2</sup>
/s. The activation energy values varied from 18.27 to 19.61 kJ/mol over the
proposed range of drying temperature and RF power.},
