Tech Profile

IPR Status : CSIR-CIMAP Know-how

Application/User : For distillation of high value water miscible essential oils from aromatic crops like rose, geranium, lavender, chamomile etc.

Level/Scale of Development : Variable : Can be designed from 100 kg herb / batch capacity to 1000 kg herb / batch depending on the bulk density of the aromatic herb to be distilled

Status of Commercialisation : CSIR-CIMAP Improved Cohobation Distillation Units have been successfully commercialized and has been installed and transferred to several farmers/ entrepreneurs and industries throughout the country

Environmental Considerations : Uses agro waste / distilled waste as fuel. Due to presence of chimney no pollution at workplace

Major Raw Materials to be Utilized : The equipment / unit are based on CSIR-CIMAP knowhow, 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

Major Plant Equipment and Machinery Required : The unit can be installed independently within a entrepreneur / farmers field or shed

Techno-Economics : The cost of the unit varies as per the capacity of unit, crops to be distilled, material of construction and other technical features etc.

Salient Technical Features

As compared to the directly fired type field distillation units the CSIR-CIMAP 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 and less time.

Salient Features.

Higher steam generation as more heating surface area.

Incorporated with a packed stripping column.

Lesser time for distillation approx 30-40 % time saving.

More fuel efficient, 20-30% fuel saving.

Less oil losses due to less vaporization and better oil separation device.

Utilizes agro waste / spent distillation waste as fuel No smoke in work area due to provision of chimney.

Technology Package

CSIR-CIMAP offers a complete technology package for setting up of the Cohobation type distillation units for essential oils. The technical knowhow / consultancy package includes designing, fabrication, installation and commissioning of the unit with trial runs and training to operators.
