The study conducted at a cooperative dairy plant having the capacity of 50,000LPD revealed that out of total units 971 thousand, about 80 percent of the electricity was consumed together in refrigeration, pasteurization and polypack sections. Only 1.67 percent of the total electricity was consumed in the product section. The steam condensate recovery in milk pasteurization was 200 litres per hour at an average temperature of 80°c, which was not being recycled and drained. If the water condensate were re-utilized, therewould be saving in soft water as well as thermal energy. Refrigeration requirement for pasteurized milk was found to be 61.35 kilocalories per unit. Out of the total refrigeration, the electricity contributed to the maximum percentage of the total cost about 55 percent. In the case of water utilization, washing and cleaning of trays and cans and overall floor cleaning of plant utilized about 50 percent of the total water. Cost of water pumping was found to be 8.38 per kilolitre of water.
