The ice making principle of a flake ice machine is to quickly condense the water on the inner wall of the evaporator barrel into ice, which is then scraped off by a precision steel ice knife and formed.
When water at normal temperature encounters -20 ℃ refrigerant on the inner wall of a copper evaporation barrel, the temperature will quickly transmit. After obtaining the temperature, the refrigerant will boil and evaporate into gas, and water will naturally quickly form ice on the inner wall.
Subsequently, the ice skate will cause the entire piece of ice to fall off, and the water will circulate on the inner wall again, thus replicating the ice. This is also why the speed of ice making from sheet ice is very fast.
The refrigerant that evaporates will be extracted by the compressor to maintain a pressure of 2 bar inside the evaporator, which is called evaporation pressure.
The refrigerant vapor extracted by the compressor enters the condenser through the condensing pipeline.
