چکیده
In this study the physical and thermal properties of baobab (Adansonia digitata) fruit pulp powder which are essential for designing engineering processes, material handling, storage, equipment design and fabrication were determined. The physical properties, namely, mean particle size, bulk density, true density and porosity were determined. Also, angle of repose and coefficient of friction were tested on mild steel, plywood and PVC plastic which are probable engineering materials for construction of food processing equipment. The specific heat capacity, thermal diffusivity and thermal conductivity were also determined. The mean particle size of the powder was 0.953 mm, while the bulk density, true density and porosity were found to be 301 kg/m 3 , 1167 kg/m 3 and 73%, respectively. The angle of repose and coefficients of static friction of the fruit pulp powder were found to be 40.63 o and 0.8339, 39.18 o and 0.7796, 37.28 o and 0.7501, respectively for mild steel, plywood and PVC plastic surfaces. The specific heat capacity and thermal conductivity decreased with increase in temperature, while thermal diffusivity increased from 1.217×10 -5 to 2.341×10 -5 m 2 /s within the temperature range of 40 and 60 o C.
