Renewable
energy system is a crucial issue for sustainable development. Thermodynamic analysis, especially exergy
analysis plays an important role to evaluate sustainability of the industrial
processing systems. Food production industry is one of the energy consuming
sectors and dairy industry could be placed at one of the top substantial amount
of energy consuming food industry segments. Hence, in this study, thermodynamic
analysis of a milk pasteurization system assisted by a renewable energy
resource -geothermal energy was investigated. In this regard, for the
pasteurization of 1 kg/s milk at 76°C the
required pasteurization capacity was 21.88 kW. In case of using geothermal
fluid at 100°C the exergetic efficiency
of the whole system was computed 71.05% as the first law efficiency and 56.81%
as second law efficiency, respectively. According to the exergy analysis the
biggest exergy destruction rate was seen in the absorber as 4.577 kW.
Additionally, in order to develop the system’ efficiency the optimum operating
conditions of the system components were determined such as absorber,
condenser, evaporator, heat exchanger.
