Industrial Ice Maker Principle: Water first automatically enters a water reservoir through an inlet valve. It's then pumped by a water pump to a distribution pipe, which evenly distributes the water to the evaporator, where it's cooled by the low-temperature liquid refrigerant. At this point, the water is cooled to freezing point. The water that reaches freezing point solidifies into ice, while the water that doesn't freeze in the evaporator flows back into the water reservoir, where the pump begins the cycle again.   When the ice reaches the desired thickness, it enters the de-icing phase. At this point, high-pressure hot air from the compressor is directed through a reversing valve to the evaporator, replacing the low-temperature liquid refrigerant. This creates a film of water between the ice and the evaporator, which pulls the ice away from the evaporator, where it falls freely by gravity into the ice storage tank below.
