Abstract

The present study examined a repeated pressing of bulk pumpkin seeds heated at temperatures of 40, 60 and 80 ℃ for 1 hour and compressed under an axial loading at a maximum load of 200 kN and speed of 5 mm/min. The sample temperature of 23 ℃ served as the control. The pressing vessel of diameter 60 mm with a plunger was used with the initial pressing height of the sample measured at 70 mm (87.38 g). Each sample was repeatedly pressed four times to recover the maximum oil output from the bulk seeds and the residual oil in the seedcake. The force-deformation curves were obtained where the area under the curve represents the energy based on the trapezoidal rule. Oil yield (%) and oil expression efficiency (%) were also calculated. The correlation results were not significant (P > 0.05) indicating that the calculated parameters were not affected by the heating temperatures with or without the control temperature. However, the maximum mass of oil of 23.62±1.52 g with the corresponding oil yield of 29.64±2.29%, oil expression efficiency of 88.40±6.82% and energy of 2475.79±20.90 J was obtained at the heating the temperature of 40 ℃ and the time of 60 min.
