Operation time
It takes about 20-35 minutes to produce a set of 24 ice cubes. The length of one cycle of the ice
maker (ice production and ice harvest) differs depending upon the cleanliness of the ice maker,
the ambient temperature, and the temperature of the water supplied to the ice maker. It takes
about 8-10 hours to fill the empty ice container with ice.
Ice production
The ice production process largely consists of two cycles, ice production and ice harvest. 24
pieces of ice are produced with each cycle of ice production and ice harvest.
When water is sprayed on to the surface of the frozen evaporator, the ice production cycle starts.
Once the ice has formed, the ice harvest cycle starts. The time taken for both cycles together is
about 20-35 minutes.
Ice production cycle
As the ice production cycle progresses, the compressor cycles the refrigerant, the fan motor
circulates the air, and the pump motor circulates water. Once the surface of the evaporator
absorbs the heat from the water, the heat moves to the condenser and with the help of the fan,
the heat is removed . The heat is transferred to the air and the heated air is removed from the ice
maker. At the same time, ice is produced on the surface of the evaporator (at the top of the ice
maker). When the surface of the evaporator has sufficiently cooled, the ice production cycle stops
and ice harvest is started using the program installed in the ice maker.
Ice harvest cycle
The compressor works during the progress of the ice harvest cycle, but the pump and fan
motors are shut off. The hot gas and water supply valves open. When the two valves are
opened and the frozen surfaces are heated, ice drops down into the container.The ice
harvest cycle is now complete and the ice production cycle starts again using the program
installed in the ice maker.
How water is used for ice making
The ice maker starts its work with a fixed quantity of water that has been fed into the water
trough. When water is sprayed onto the surface of the evaporator, the water not containing
mineral impurities freezes and attaches to the evaporator. The water containing impurities drops
down into the water container. During the progress of the ice production cycle, the
mineral impurity level in the water container rises.
During the progress of the ice harvest cycle, water is fed to the ice maker, thereby diluting
the water in the container, and washes a part of the concentrated minerals through the
drain hose.
