The thermal properties (specific heat capacity, thermal conductivity, and thermal diffusivity) of Jack bean seed (Canavalia ensiformis) were determined for designing the equipment necessary for thermal processes. These thermal properties were determined at 5, 10, 15, 20, and 25 % moisture contents and temperatures at 30, 40, and 50 º C using the KD2 Pro thermal analyzer. Results showed that the specific heat capacity ranged from 1.55 to 2.47 kJ/kgK, 1.26 to 1.84 kJ/kgK and 1.32 to 1.99 kJ/kgK; thermal conductivity 0.21 to 0.47 W/mK, 0.34 to 0.52 W/mK, and 0.26 to 0.60 W/mK and thermal diffusivity 0.25 to 0.41 x 10-7 m²/s, 0.32 to 0.57 x 10-7 m²/s, and 0.32 to 0.60 x 10-7 m²/s at 30, 40, and 50 °C respectively for the moisture ranges studied. The temperature and moisture content effects were not significant (p>0.05) with specific heat and thermal diffusivity but were significant (p<0.05) with thermal conductivity in third-order polynomial. A non-linear relationship was established between the three thermal properties and moisture content within the studied temperature range. The resulting regression models for the thermal properties gave a high coefficient of determination (R2 ≥0.7995) which implies that the parameters can be used to describe the relationships between temperature, moisture, and thermal properties of Jack bean seeds.
