OPTIMALISASI DESTILASI NILAM KERING MELALUI PEMBEKUAN PRA DESTILASI
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 process could
be expected to damage the tissue at the cellular level. Pure research on
laboratory scale was used as the experiment method in this study. Freezing
temperature pasca-distillation was variated on -13,4 ºC, -19,6 ºC and -24,8 ºC
and without freezing process. While distillation process was varied on 95 ºC,
105 ºC dan 115 ºC. In this study, patchouli was distilled on wet and dry
condition. LPG was used with automatically combustion control system of for
keeping the temperature stability, increasing the capacity and quality of
patchouli oil and reducing the production cost and the distillation time to
less than 6 hours The stable distillation temperature was able to raise the
volume of oil per kilogram of dry weight raw material and decrease the
distillation time to less than 5 hours. Patchouli oil volume produced per
kilogram of dry raw materials post freeze predistillation increased with
increasing the distillation temperature. The low freezing temperature of the
pre-distillation produced the high volume of patchouli oil per kilogram of raw
material. Pre-distillation on the freezing process of dried patchouli was able
to shorten the time of maximum distillation only in 3 hours. The range of
distillation temperature on 95 ⁰C, 105 ⁰C and 115 ⁰C produced the different
colors of patchouli oil from light brown to dark brown color.
