| Abstract: | A simple first order kinetic model has been
developed for steam distillation of lemongrass (Cymbopogon spp.). This rate
model was tested on pilot scale, steam distillation units, with lemon grass
batches of 70 to 1000 kg. For intimate contact of lemongrass and steam, two
improved direct steam spargers were provided in these units. It is observed,
that, the loose packing of plant material inside distillation still and steam injection
rate, increases the oil yield. Straight line behaviour with intercept on time
axis of the above rate model explains, that, oil production inside the
distillation unit is not instantaneous, but some time is required for wetting
of grass for the diffusion and osmosis of oil. |
