In the vast open space in front of the Aavin dairy in Sholinganallur, the agency has installed Concentrated Solar Thermal (CST) systems. Aavin sources said that during pasteurisation, milk is heated to 78 degrees Celsius using steam that is generated through a boiler using furnace oil as fuel. Similarly, 100 of Aavin’s 299 bulk milk coolers in the State are using solar water heaters for cleaning the systems. Aavin has been using solar power systems to heat water in all dairies in Chennai. This is the second such system installed by the Tamil Nadu Cooperative Milk Producers Federation, popularly known as Aavin.
