Abstract

The Process of extracting oil from the leaves or stems cells by damaging the cell which usually done before or during distillation process. Damaging the cell can be done by mechanical process or freezing process. Chopping the leaves was done to damage the cells through the mechanical process, however the damage have not been able to destroy up to the celular level. While the freezing proces could be expected to damage the tissue at the celular level. Pure research on laboratory scale was used as the experiment method in this study. Freezing temperature pasca-distillation was variated on -50C, -100C and withouth freezing processs. In this study, patchouli was distilled on dry condition. LPG was used with automatically combustion control system of for keeping the temperature stability. The stable distillation temperature was able to raise the volume of oil per kilogram of dry weight raw material. Patchouli oil volume produced per kilogram of dry raw material post freeze pre- distillation increased. The low freezing temperature of the pre-distillation produced the high volume of patchouli oil per kilogram of raw material. The distillation produced the different colors of patchouli oil from yellow until light brown. Keywords: Optimalization, Distillation, Dry Material, Patchouli Oil, Freezing Process
