The flake ice is thin, dry and loose white ice with a thickness ranging from 1.0 mm to 2.5 mm. The shape of the slices is irregular, and the diameter is about 12 to 45 mm. Flake ice has no sharp edges and corners and will not stab frozen objects. It can enter the gap between the objects to be cooled, reduce heat exchange, maintain the temperature of the ice, and have a good moisturizing effect. Flake ice has excellent refrigeration effect and has the characteristics of large and rapid refrigeration, so it is mainly used in various large-scale refrigeration facilities, food quick freezing, concrete cooling and so on.
Flake ice machine vertical evaporator
The evaporator of the flake ice machine is a vertically erected barrel structure, which is composed of the ice blade, the main shaft, the sprinkler tray, and the drain tray, which are the main components of ice making. Driven by the reducer, they slowly rotate counterclockwise.
Principles of flake ice making
The water enters the water diversion tray from the water inlet of the evaporator of the flake ice machine, and the water is evenly sprinkled on the inner wall of the evaporator through the sprinkler pipe to form a water film; the water film exchanges heat with the refrigerant in the evaporator flow channel, and the temperature is rapid When lowered, a thin layer of ice is formed on the inner wall of the evaporator, which is broken into pieces of ice under the squeeze of the ice skates, and falls into the ice storage through the ice falling port. Part of the uniced water flows back into the cold water tank from the water return port through the water tray, and then passes through the cold water circulation pump.
flake Ice making cycle
Through the supplementary water valve, the water automatically enters a water storage tank, and then the water is pumped through the flow control valve to the diverter head, where the water is evenly sprayed on the surface of the ice maker and flows through the ice maker like a water curtain On the wall surface, the water is cooled to the freezing point, and the water that has not been evaporated and frozen will flow into the water storage tank through the porous tank, and the circulation will restart.
Ice picking cycle
When the ice reaches the required thickness (under normal circumstances, the thickness of the ice is 1.5-2.2mm), the hot air discharged from the compressor is re-introduced into the wall of the ice maker to replace the low-temperature liquid refrigerant. In this way, a thin film of water is formed between the ice and the wall of the evaporation tube. This water film will act as a lubrication when the ice falls freely into the groove below by gravity. The water produced during the ice picking cycle will return to the water storage tank through the porous tank, which also prevents the wet ice from being discharged by the machine.
It can be realized with air-cooled, water-cooled or evaporative condenser. The evaporative type is installed higher than the ice machine, the water-cooled condenser is installed below the ice machine or under the refrigeration system, and the air-cooled condenser is installed in the ice machine according to the actual situation. It can also be installed outdoors. If necessary, water-cooled condensers can be used on ships or on shore, using sea water for cooling. Evaporative cooling can be used when the ambient air temperature is high, but from the perspective of efficiency and economy, it is not suitable for water-cooled or air-cooled refrigeration.
