Improved Cohobation Distillation Units have been successfully commercialized and have been installed and transferred to several farmers / entrepreneurs and industries throughout the country.
Application : For distillation of high value water miscible essential oils from aromatic crops like rose, geranium, lavender, chamomile etc.
Level/Scale of Development : From 100 kg herb / batch capacity to 1000 kg herb / batch depending on the bulk density of the aromatic herb to be distilled.
Design Particulars : The equipment / unit is based on CSIR laboratories know-how, designs and specifications. The unit is fabricated as per requirement of the crops to be distilled. The unit can be made of MS / SS depending on the crop. All contact parts, however, are made of high grade stainless steel.
As compared to the directly fired type field distillation units, these cohobation type distillation units are more efficient and are able to distill out the water miscible components of any essential oil. Cohobation which implies recycling is carried out within the unit so as to enhance the oil recovery. These units have been designed as a standalone unit with an inbuilt packed stripping column through which the water miscible components of any oil are recovered. These units are also built with an inbuilt calandria unit which enhances the steam generation rate thus higher oil recovery in less time.
