The Milky FJ 50 E is a multipurpose stainless dairy kettle designed for controlled heating and cooling of milk for products such as pasteurized milk, cream, yogurt, and cheese. It’s an open-type unit that uses a double-wall water jacket for gentle, even heating and water-jacket cooling. How it heats: Think of the FJ 50 E as a stainless pot sitting inside a second stainless pot: The inner pot holds your milk (or mix). The space between the inner and outer walls is the water jacket. An electric heater warms the water in the jacket, and that warm water transfers heat through the stainless wall into the milk. This means the milk is not heated directly by an element. Instead, it’s warmed by the surrounding hot water in the jacket, which helps provide more uniform heat. Control features (time + temperature) The control unit allows you to set: Temperature setpoint: 68°F to 210°F Holding time: 0 to 999 minutes Important detail about the temperature display! The temperature you set on the controller refers to the secondary heating water (the jacket water), not the milk itself. Because heat has to travel: jacket water ? stainless wall ? milk, the milk temperature will lag behind and should b
