Tejomaya is a company who is working in Agriculture domain with energy solutions. Tejomaya is convinced with the technology developed by CSIR-CIMAP seed technology and as well as extraction of the extraction of essential oil from various grasses using a patented distillation process. The essential oil is used in most of all sector producing cosmetic products, medicated products, and perfumes. CSIR- Central Institute of Medicinal and Aromatic Plants, Government of India, popularly known as CIMAP, is a frontier plant research laboratory of Council of Scientific and Industrial Research (CSIR). Established originally as Central Indian Medicinal Plants Organization (CIMPO) in 1959, CIMAP is steering multidisciplinary high-quality research in biological and chemical sciences and extending technologies and services to the farmers and entrepreneurs of medicinal and aromatic plants (MAPs) with its research headquarter at Lucknow.
CSIR-CIMAP after long research they developed seeds of various grasses like lemongrass, Mint, Rose, Lavender, Geranium, Palmarosa, Java etc which contain more percentage of essential oil in it as compared to traditional available. Also, they developed patented essential oil extraction process through distillation which required Heat energy for extraction of oil from the various grass. Currently, they are using wood as a primary source for heat generation to heat the water at 95 degrees which is causing a lot of pollution in the environment as well as the force to cut the trees. Instead of wood Green life Proposed CPC system for heat exchange as heat requirement is only below 95 degrees and hence can easily extract the essential oil without burning.
As we all know India has been blessed with tremendous renewable energy potential. Solar energy is everywhere, it’s abundant and we’ll practically never run out. Even in mid-winter, we are blessed with a moderate amount of natural daylight provided courtesy of the sun. It might not be sunny every day but we are still experiencing radiation from the sun and it is this which can be gleaned for our own renewable energy purposes. Thus the need for finding a long-lasting energy resource is over.
ABOUT COMPOUND PARABOLIC COLLECTOR (CPC)
CPC Design Concepts – An interesting design for a concentrating collector makes use of the fact that when the rim of a parabola is tilted toward the sun, the rays are no longer concentrated to a point, but are all reflected somewhere below the focus. The rays striking the half of the parabola which is now tilted away from the sun are reflected somewhere above the focus. This can be seen in the Figure where the rays on the right-hand side are reflecting below the focus and the rays on the left-hand side are reflecting above the focus. If the half parabola tilted away from the sun is discarded, and replaced with a similarly shaped parabola with its rim pointed toward the sun, we have a concentrator that reflects (i.e. traps) all incoming rays to a region below the focal point.
Since the rays are no longer concentrated to a single point, this design is called a non-imaging concentrator. A receiver is now placed in the region below the focus and we have a concentrator that will ´trap´ sun rays coming from any angle between the focal line of the two parabola segments. Receivers can be flat plates at the base of the intersection of the two parabolas, or a cylindrical tube passing through the region below the focus. The basic shape of the compound parabolic concentrator (CPC) is illustrated in Figure below.
As CSIR-CIMAP after long research they developed seeds of various grasses like lemon grass, Mint, Rose, Levendor, Jirenium, Pamarosa, Java etc which contain more percentage of essential oil in it as compare to traditional available. Also they developed patented essential oil extraction process through distillation which required Heat energy for extraction of oil from various grass. Currently, they are using wood as a primary source for heat generation which is causing lot of pollution in environment as well as force to cut the trees. Instead of wood Green life Proposed CPC system for heat exchange as heat requirement is only 95 degree and hence can easily extract the essential oil without burning.
|Existing Arrangement||Wood fired Boiler|
|Heat required in form of||Hot water|
|Water Temperature||95 degree hot water|
|Working Timing||9:30 am to 4:00 PM|
|Total Energy required||1500000 Kcal per day|
|Required temperature||95 degree|
|Present Fuel (wood) Consumption||Up to 600 Kg per day|
After the survey green Life team find that we need to not disturb their existing setup, instead we can provide energy from our CPC system to extra the essential oil instead of burning of wood.
Below is the proposed solution for their existing setup to convert it on solar.

|Heat required for application||95 degree|
|Proposed System||Thermic Oil based|
|Heat provided in form of||Hot Oil|
|Integrated with Existing System||Yes|
|New system will be integrated||No|

Piping and Insulation
PROPOSED SCHEMATIC DIAGRAM
Total 720sqmts of Compound Parabolic Collector (CPC) solar thermal field will be installed which will help in collecting thermal energy in the form of thermic oil. We rotate the thermic oil through the CPC installed at. With every rotation, oil will gain temperature and same will be utilized by the user in its process heating application to heat water at the required temperature and extract the essential oil from the grass at a controlled temperature as shown in the above diagram.
