Dairies run on cold water the way breweries run on glycol, and for a reason the product dictates: milk must be chilled fast, in equipment cleaned daily, without any risk of freezing it onto a heat-exchange surface. The sector's answer is ice water, water held at 0.5 to 1 ยฐC, and behind it one of industrial refrigeration's most elegant devices: the ice bank, which turns a refrigeration plant into a battery. This lesson covers the dairy cold chain from silo to despatch, the ice-water system at its centre, and why that system makes dairy refrigeration uniquely schedulable.
