Does the flake ice machine consume electricity?

The structure of the flake ice machine determines that the flake ice machine does not consume electricity. The flake ice machine does not need to de-ice like the cube ice machine, tube ice machine, and block ice machine, which is more energy-saving.

The flake ice machine is mainly composed of a compressor, an expansion valve, a condenser, and an evaporator, forming a cycle-closed refrigeration system. The evaporator of the flake ice machine is a vertical barrel structure, which is mainly composed of ice blades, a main shaft, a sprinkler plate, and a water receiving plate. Driven by the reducer, they slowly rotate counterclockwise. Water enters the water distribution plate from the water inlet of the evaporator of the flake ice machine, and through the sprinkler plate, the water is evenly sprinkled on the inner wall of the evaporator to form a water film; the water film exchanges heat with the refrigerant in the flow channel of the evaporator, and the temperature drops rapidly , A thin layer of ice is formed on the inner wall of the evaporator, and under the extrusion of the ice knife, it breaks into flakes of ice and falls into the ice storage bin from the ice outlet. Part of the unfrozen water flows back into the cold water tank from the water return port through the water receiving tray, and enters the next cycle through the cold water circulation pump.

What kind of refrigerant does the flake ice machine use?

The flake ice machine is composed of four basic components: refrigeration compressor, condenser, expansion valve and evaporator. They are connected in turn by pipes to form a closed system. The refrigerant circulates continuously in the system, undergoes state changes, and exchanges heat with the outside world. Refrigerant is an important medium for flake ice machines, which is equivalent to the blood of the human body.

The flake ice machines currently on the market mainly use R22 and R404 refrigerants.

The small flake ice machine with a daily output of 300 kg to 3 tons mainly uses R404 refrigerant, which is an environmentally friendly refrigerant that does not damage the ozone layer.

Large and medium-sized flake ice machines with a daily output of 5 tons to 60 tons mainly use R22 refrigerant. R22 refrigerant is cheap and has excellent thermal performance, but it will destroy the ozone layer.

Now large and medium-sized flake ice machines also use R134a environmentally friendly refrigerant, but the thermal performance of R134a is only 60% of that of R22. The heat transfer rate of R134a is 90% of R22, so a larger cold machine is required. In a comprehensive comparison, flake ice machines using R134a refrigerant are half as expensive as R22 flake ice machines.
