Normally an industrial ice making machine produces ice on vertically suspended, double-walled cylindrical evaporators. Chilled water is continually re-circulated over the inner and outer surfaces of the evaporators as refrigerant passes through the space between the two ice making surfaces. This process makes use of 100% of the evaporators??¡ê¡è surface and provides ultra fast production with utmost efficiency of heat exchange. Ice making water is re-circulated by a pump from the stainless steel made sump or reservoir, where the proper water level is kept by a floating valve. Water flows onto the inner and outer evaporator surfaces simply by tube water distributors. The freezing period is determined by a repeating cycle timer.
If the ice reaches the desired thickness (programmable), hot gas from the compressor is introduced into the annular space breaking the ice bond from the evaporator surfaces realizing the concentric cylinders of ice which fall by gravity into ice cutter assembly. The rotation of the ice cutter delivers the ice across the grid and makes the ice fall into the storage bin.
