Dairy processing is a precision heat business. Pasteurization laws specify exact temperature-time curves — 72 °C for 15 seconds in HTST plants, 135 °C+ for UHT — and the plate heat exchangers that deliver them depend on perfectly stable steam or hot water on the service side. Evaporators and spray dryers that turn milk into powder are even larger consumers, and every product changeover triggers a full CIP cycle of hot caustic and acid washes, all heated by the boiler house.
Because milk arrives daily and spoils quickly, dairy plants have zero tolerance for boiler downtime — a lost day is not lost production, it is dumped raw milk. Twin packaged WNS steam boilers in a duty/standby arrangement are the standard answer: fast steam-raising for morning start-up, high turndown across the day's varying loads, and dry steam that keeps heat-exchanger surfaces from scaling and burning-on product.
Hygiene extends to the steam itself: culinary-grade filtration and careful feedwater treatment are typical, and our boiler specification for dairies includes the water-treatment plant and blowdown handling needed to meet food-safety audits.
