Mechanical behaviour of selected bulk oilseeds under compression loading

Popis výsledku v původním jazyce

Mechanical behaviours of bulk seeds of camelina, pumpkin and sesame relevant to cold pressing were investigated at moisture contents of 7,04, 8,60 and 6,06% (d.b.), 80mm pressing depth and a compressive force of 100 kN, applied uniformly at 10 mm min-1. Deformation varied with incremental force and among crops at peak compression. Deformations in Camelina, Sesame and Pumpkin seeds were 40,2, 41,6 and 50,9 mm at peak compression. Oil point pressures of Sesame, Camelina and Pumpkin seeds were 3,83, 7,49 and 8,83 MPa, respectively. Oil recovery at the applied load was similar in Camelina and Sesame but significantly lower in pumpkin seeds. Volume energy requirement for the expression of oil from camelina, pumpkin and sesame seeds were 2,56, 1,72 and 1,46 MJ m-3, respectively. An assessment of the pressed cake after oil expression revealed that the materials were capable of further deformation under compression.
