Answer:
Pasteurisation makes sure milk is safe to drink (by killing any bacteria) and also helps to prolong its shelf life. The process of pasteurisation involves heating milk to 71.7°C for at least 15 seconds (and no more than 25 seconds). ... The equipment which is used to heat and cool the milk is called a 'heat exchanger'.
