8. The icemaking process The Follett ice machine uses a stainless steel jacketed evaporator and operates on a continuous freezing cycle Water is supplied to the evaporator from the water reservoir where the water level is controlled by a float valve This valve also shuts off the water supply when the ice machine is not running When the ice machine is running a layer of ice forms on the interior surface of the evaporator This ice is continuously removed by a slowly rotating 12 RPM auger The auger carries the ice upward into the cavity formed by the top bearing housing and the compression loop where it is compressed to remove excess water When the ice reaches the desired hardness it rotates within the cavity and is forced through a discharge port and compression nozzle and into the ice transport tube The discharge tube and compression nozzle are slightly restricted to further compress the ice and produce the desired hardness As the formation of ice continues ice in the transport tube is pushed through the tube to the storage compartment in the ice dispenser A solid state control board located in the electrical box of the ice machine controls the normal operation of the ice machine and monitors gearmotor torque This control board will shut down the ice machine should an over torque condition occur It is very important that you familiarize yourself with the operational sequences detailed in this manual before attempting to
