A bulk milk cooler is an essential refrigeration unit designed to chill and store large volumes of milk to maintain freshness and prevent spoilage. Typically made from stainless steel for durability and hygiene, it features a large, insulated tank that can hold several thousand liters of milk. The cooler uses advanced refrigeration technology to rapidly lower the milk’s temperature to around 4°C (39°F), preserving its quality and extending its shelf life. It includes a cooling coil or plate system, an agitator for even temperature distribution, and temperature controls for precise monitoring. Many bulk milk coolers are equipped with automatic cleaning systems to ensure sanitary conditions. Ideal for dairy farms and processing facilities, they help ensure that milk is kept at optimal temperatures from milking to delivery, meeting industry standards for quality and safety.
