REVIEW PAPER ON PERFORMANCE ENHANCMENT OF DAIRY INDUSTRY BY ENERGY CONSRVATION ANALYSIS

Energy is critical component of dairy industry. Dairy industry depends on fossil fuels for energy supply. It is known fact that our fossil fuel reserves are finite and we should utilize these resources judiciously. Energy conservation is only route that can get better mileage out of the available resources. The need is to evolve an appropriate strategy for energy conservation to achieve economical and environmental benefits. Energy conservation in dairies is not the suppression of demand for energy use, but efficient use of energy and steep rejection of energy wastage. Energy Conservation in dairy plant means to develop a methodology to achieve energy saving to reduce energy costs in processing system. Energy is one of the fourth pillars for production of dairy products in addition to land, labour and capital. In dairy industry, processing of milk and milk products require considerable amount of energy in the forms of the heat and electricity. A major amount of electrical energy is used for running auxiliary equipments while heat energy is used for heat treatments of milk and milk products in the plant. The cost related to this energy consumption is entitled as overhead cost. One often overlooked, but major overhead is energy costs. Dairy producers are looking the ways to reduce these overheads. Energy Conservation will help to reduce the energy costs which will reduce the processing costs. It leads to develop capable processing system with optimum energy consumption in dairies which will result into the performance enhancement of dairy plant.
