Abstract

India is a world leader in milk production, with an annual production of 230.6 MT. Only 30 percent of milk is currently handled in the organized sector. A cheap source of reliable energy is needed to shift the unorganized sector to an organized sector, as dairy operations are energy-intensive. Solar energy is renewable, inexhaustible, promising, and abundantly available in India. In the literature, it was found that dairy operations such as sterilization of milk can be done using solar energy. However, the limited sunshine hours make it possible to handle only a limited quantity of milk day-to-day. This paper aims to discuss the performance evaluation of a solar heat reservoir to enhance the operational hours during the daytime when solar radiation is insufficient to provide the required energy to carry out the operations. It was found that by using the designed thermal reservoir, the working hours for milk processing were enhanced by 25 to 50 percent, depending on the ambient solar conditions.
