The effects of heating temperatures and time on deformation energy and oil yield of sunflower bulk seeds in compression loading
Kabutey, A.; Herak, D.; Sigalingging, R.; Demirel, C. (Iop Publishing Ltd, 2018)The deformation energy (J) and percentage oil yield (%) of sunflower bulk seeds under the influence of heat treatment temperatures and heating time were examined in compression test using the universal compression testing ... -
Energy demands for pressing Jatropha curcas L. seeds
Herak, D.; Gurdil, G.; Sedlacek, A.; Dajbych, O.; Simanjuntak, S. (Academic Press Inc Elsevier Science, 2010)Experiments were carried out to determine required energy for pressing Jatropha curcas L. seeds (IPB2 variety from Indonesia), at three stages of fruits maturity, i.e. green (unripe), yellow (ripe) and brown (over-ripe), ... -
Numerical estimation of deformation energy of selected bulk oilseeds in compression loading
Demirel, C.; Kabutey, A.; Herak, D.; Gurdil, G. A. K. (Iop Publishing Ltd, 2017)This paper aimed at the determination of the deformation energy of some bulk oilseeds or kernels namely oil palm, sunflower, rape and flax in linear pressing applying the trapezoidal rule which is characterized by the area ...
