Abstract

The tea tree oil extraction conditions, including type of distillation method, steam flowrate, plant’s raw state, particle size and loading ratio, were optimized. The optimal extraction conditions were initially verified with the experiments which were carried out in a linear manner. The results demonstrate that steam distillation of fresh tea tree with its size as 1 cm at steam flowrate of 6.2 mL/min and loading ratio of 1:0 for two hours are the most optimal extraction conditions. A mathematical model that developed from Fick’s law in unsteady state was then used to validate the experimental data. Both data are in consent, with the diffusivity coefficient and mass transfer coefficient of tea tree oil extraction under the optimal extraction conditions to be 1.08 ×10-11 m2/s and 4.56×10-8 m/s respectively. The industrial scale tea tree oil extraction plant was designed to consist of a boiler (1157.5 kW), four stills (0.46 m3 per still), four condensers (220.6 kW per condenser) and four decanters (0.066 m3 per decanter). The oil yield was estimated to be 0.9 w/w%, correlating with the assumptions made
