Operation time
It takes about 20-35 minutes to produce a set of 24 ice pieces. The length of one cycle
of the ice maker (ice production and ice removal) differs depending upon the cleanness
of the ice maker, the surrounding temperature, and the temperature of the water supplied
to the ice maker. It takes about 10-12 hours to fill the empty ice container with ice.
Ice production
The ice production process largely consists of two cycles-ice production and ice removal.
24 pieces of ice are produced with each cycle of ice production and ice removal.
When water is sprayed on to the surface of the frozen iceforming mold, the ice production
cycle is started. When ice is removed and water is supplied to ice maker, the ice removal
cycle is started. The time taken for both cycles together is about 20-35 minutes.
Ice production cycle
As the ice production cycle progresses, the compressor exhausts the refrigerant, the fan
motor circulates the air, and the pump motor circulates water. When the surface of
the ice-forming mold absorbs the heat from the water, the heat moves to the part to
which the fan supplies water. 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 ice
-forming mold (at the upper end of the ice maker). When the surface of the ice-forming
mold has sufficiently cooled, the ice production cycle stops and ice removal is started by
the program installed in the ice maker.
Ice removal cycle
The compressor works during the progression of the ice removal cycle, but the pump motor
and fan motor are stopped. The hot gas valve and water supply valve work. When the two
valves are opened and the frozen surfaces are heated, ice drops down into the container.
Then the ice removal cycle is stopped and the ice production cycle is started again by
the program installed in the ice maker.
How to use water for ice maker
The ice maker starts its work with the fixed quantity that has been fed into the water
container. When water is sprayed on to the surface of the ice-forming mold, the water not
containing mineral impurities freezes and attaches to the ice-forming mold. The water
containing impurities drops down into the water container. During the progression of the ice
production cycle, the mineral impurity level in the water in the water container rises.
During the progression of the ice removal 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 pipe.
