Pressing of vegetable oils plays an important role in the food processing. This study
described the compression behaviour of copra (Cocos nucifera L.) using the universal
compression testing machine and vessel diameter of 60 mm with a plunger. The influence of heat
treatment on oil recovery efficiency and specific mechanical energy were determined.
Compression tests at the rate of 1 mm s
−1 under five different temperatures 20, 40, 60, 80 and
100 °C were performed. The measuring range of force was between 0 kN and 50 kN. It has been
found that the amount of obtained oil increased and specific mechanical energy decreased with
increased temperature. Measured data were analysed by computer software Mathcad 14
(MathCAD 14, PTC Software, Needham, MA, USA). Mathematical model describing the
mechanical behaviour of bulk copra under compression loading was represented.
