Icesnow flake ice machine working principle is the closed loop heat exchange of refrigerant. Outside water flow into the water tank, then pumped into the water distribution pan evenly flows down the inner wall of evaporator. The refrigerant in the refrigeration system evaporates through the loop inside the evaporator and absorbs large amount of heat by exchanging heat with the water on the wall.As the result, the water flow over the surface of inner evaporator wall sharply cools down to below the freezing point and freezes into ice instantaneously.
