International Solar Food Processing Conference 2009 2. Summary A Department for Renewable Energy was established by BK in 1992, at the Gyan Sarovar Academy for a better World and a Solar Energy House was constructed. Since then, the solar radiation and wind speed have been continuously monitored on a computerized data logger In 1996, a solar steam cooking system for 1000 people was installed. The cooking system was sponsored by GTZ and designed by Wolfgang Scheffler / Brahma Kumaris/ Eco Centre, Valsad, and HTT, one of the leading German companies in heat transfer technology. The parabolic concentrators with a size of 7.2sq meter are made in India and have a total surface area of 190 sq meters. With an output of 650 kg steam per day, the cooker is a fine example of the successful use of solar thermal energy on large scale. In January 1998, a solar steam cooking system for a maximum of 35,000 meals per day was constructed in Shantivan Complex, Abu Road. This system consists of 84 newly developed concentrators of 9.5sq meter and generates the steam directly in the receivers. The system generates around 3500 Kg steam per day. The plant was successfully commissioned and tested and has been running excellently for the last nine years. A second steam cooking system for 600 people was set up in Yelapur (Hubli), and an additional system for 2000 people was constructed at Om Shanti Retreat Centre near Delhi. In 2003, one more solar steam cooking system with financial assistance of MNRE with an increased dish size of 12.6 sq m and new improved layout to provide steam for the canteen, sterilizers and laundry was completed for the Global Hospital and Research Centre in Mt. Abu. A smaller system with 7 dishes and state of the art receiver/ Tracking / Steam tank design was completed in 2005 at the Headquarters of Brahma Kumaris in Mt. Abu. In 2006 with the help of Wolfgang Scheffler a new 16sq meter prototype dish was successfully designed and tested as an R& D together with the MNRE. Further solar steam systems with the state of the art 16 sq meter dishes are in planning. In 2008 Brahma Kumaris designed, build and tested together with Wolfgang Scheffler a new and innovative 50sq meter prototype dish for power generation and steam production. The solar steam cooking systems developed by the Brahma Kumaris have been recognized by the ministry of Non Conventional energy sources and are eligible for 50 % grant of the total costs. 30
International Solar Food Processing Conference 2009 Our experience with Solar Concentrating Steam System in our Food Industry Ghanshyam Lukhi Tapi Food Products 112, Sahyog chambers, Mini Bazar, Varachha Road, Surat-395006.India. email:tapifood@gmail.com India is blessed with abundant sunshine and Sun has special position and Status in our Society and is worshipped. We at Tapi Food Products decided to tap solar energy for our process Industry because we are convinced that use of solar energy is good for everyone in many ways. First it reduces energy cost for our food processing because after one time investment there is hardly any running cost Second our company gets green image Third it may help in marketing our products as environmentally manufactured product and Last but most important it serves the cause of environmental protection. In our presentation we will present our case study and share our experience with other participants We have a solar system with 10 scheffler dishes generating steam which is used for concentrating juice n in making of products like Fruit jams, Jellies, Papaya tutti fruity, Syrups, Squashes, Marmalades, etc. We have been fortunate to get government support in form of subsidy and also carbon credits to make project more feasible. We are the first in India to manufacture food products by solar steam. 31
