The main objective of this research was to develop a solar energy based thermal reservoir cum heat exchanger using thermic fluid viz. paraffin oil as thermal heat storage and heat transfer medium for generation of hot water which can be used for milk processing operation like pasteurization of milk. In this research, basically three mild steel pressure vessels were constructed; one of which was simply a concentric mild steel vessel with a single cavity (configuration 1) which was only used for the preliminary study of thermic fluid and based on this, a thermal reservoir with two different configurations (configuration 2 and configuration 3) were constructed for hot water generation which could be continuously circulated for in plant processing of milk. In thermal reservoir, there were three layers viz. section 1, section 2 and section 3. Among these layers, section 1 was cavity for thermic fluid, section 2 for steam generation and section 3 was for production of hot water for circulation. In configuration 2, there was a copper pipe (section 3) for hot water circulation but due to some cons, another configuration viz. configuration 3 was developed by replacing section 3 of configuration 2 with a drum of high volume and thus a complete setup was developed for generation of hot water to be circulated for continuous processing of milk even after peak sun hours. Earlier a research study was performed in college of Dairy Science and technology, GADVASU by M.tech (Dairy Engineering) student for solar in-bottle sterilization of milk; it was found that solar energy could be effectively used up to 3 P.M. This study was in continuation with that study and thus a thermal reservoir was designed and fabricated to trap the sun’s heat energy in peak hours, which could be effectively utilized in off sun hours i.e. after 3 P.M.
