Comparison of Deformation Energy of Particular Oil-Bearing Crops

Abstract

The study focused on the description of the empirical and theoretical relationship between the force and deformation as well as the deformation energy of bulk oilseeds of oil palm, sunflower, rape and flax. Each of the bulk material initial height of 60 mm was loaded using the universal compression machine and pressing vessel of diameter 60 mm at a maximum force of 200 kN and speed of 5 mm/min. The tangent curve model was used to describe the experimental data. The amounts of numerical deformation energy of oil palm and sunflower bulk materials at a force of 200 kN were1245.55 +/- 20.41 (J) and 675.94 +/- 5.55 (J) whiles that of the analytical were 1283.96 +/- 29.55 (J) and 823.31 +/- 123.20 (J). At an optimal force of 163 kN for rape and flax bulk oilseeds, the amounts of experimental and analytical model of deformation energy were 718.27 +/- 29.41 (J) and 690.55 +/- 45.71 (J) then 600.96 +/- 4.62 (J) and 566.82 +/- 5.31 (J).
