As compared to local distillation units, CSIR laboratories have developed improved directly fired type field distillation units which are more efficient, give higher recovery and better quality of the essentials oils. The units are built with an inbuilt calandria unit which enhances the steam generation rate thus higher oil recovery.

Application/User : For distillation of essential oils from aromatic crops like Mentha, lemongrass, basil, vetiver etc.

Level/Scale of Development : Can be designed from 100 kg herb / batch capacity to 2.0 ton herb / batch

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

Design Particulars : The equipment / unit is based on CSIR 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.

Salient Features :

• Higher steam generation as more heating surface area.
• Better oil quality and recovery; 10-15% higher than local units.
• 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 condensation and separation devices.
• Utilizes agro waste / spent distillation waste as fuel.
• Better draft of flue gases due to provision of chimney.
• Less polluting.
• Better quality material of construction with all contact parts of SS.
• Highly safe : No chances of pressure build up.
