A milk boiler is a machine that heats milk to a temperature high enough to destroy any bacteria present in milk. Normally Milk boilers are used in the food industry to pasteurize milk. Milk is a liquid formed of water, fat, protein, and lactose.
Commercial Milk boilers are general in both electric and gas models. Electric milk boilers are more standard, as they are less costly to operate. Gas milk boilers are generally used in industrial settings, as they can heat milk faster than electric models.
