Milk and dairy products: production and processing costs

The total heat produced by vaporization of one kg of steam at 170°C at a pressure of 8 kg/cm 2 is 660 kcal. However, assuming the water comes into the boiler at a temperature of 20°C, the amount of heat needed to get 1 kg of steam from 1 kg of water would be: 660 kcal - 20 kcal = 640 kcal. and the monthly steam production would be
