 How the ICE Machine Works 

 

Page 9 

 

A general description of how the ICE-O-Matic Flaker works is given below: 

 

Whenever the ON/OFF switch is in the ON position (and the bin control and safety controls are closed) the machine 
will continuously make ice and deliver it into the storage bin. 
 
Water enters a reservoir through the float valve and is gravity fed into the evaporator barrel through an opening in the 
bottom of the barrel.  Water fills the evaporator to the same level as the water in the reservoir.  This level is maintained 
by a float valve which stops the flow of water into the reservoir when the reservoir becomes full. 
 
When the ON/OFF switch is turned to the ON position, the auger motor energizes.  On larger machines the 
compressor is delayed for 2 to 4 minutes.  After the compressor delay period, the compressor and condenser fan 
motor (air cooled machines only) starts causing the temperature of the evaporator to drop.   
 
The water in the evaporator freezes to the inner wall of the evaporator barrel.  A belt driven gear reducer continuously 
turns the auger inside the evaporator.  As the auger turns, it pushes the ice off of the barrel wall.  The auger also 
drives the flakes of ice upward and forces them out of the window in the barrel, through the delivery chute and into the 
storage bin.  As ice is pushed out through the evaporator, make-up water enters the bottom of the evaporator. 
 
As the level of ice in the bin rises, 
the ice will contact the 
thermostatic bin control thermal 
well.  The bin control then opens, 
shutting the machine off until ice 
is removed, allowing the bin 
control to once again close, 
starting the machine.
