| In
the Arctic-Temp Ice maker is produced on vertical suspended, double-walled
cylindrical evaporators, chilled water is continually recirculated over the
inner and outer surface of the evaporator as refrigerant passes through the
annular space between the two ice making surfaces. This process utilizes
100% of the evaporator surface and provides fast production with maximum
efficiency of heat exchange. Ice making water is recirculated by a pump from
the stainless steel sump, where proper water level is maintained by a float
valve. Water flows onto the inner and outer evaporator surface by simple
tubed water distributors. The freezing period is determined by a repeating
cycle timer with a chargeable gear rack for adjusting ice thickness. When
the ice has reached its desired thickness, hot gas from the compressor is
introduced into the annular space. The introduction of hot gas "breaks the
ice bond" from the evaporator surface, releasing the concentric cylinders of
ice, which falls by gravity into the ice breaker/crusher assembly. The
rotation of the ice breaker delivers the ice across the grid and discharges
it into the storage bib or bunker.
