SENSOR ASSEMBLY FOR DETECTING ICE CRYSTAL FORMATION ON HEAT EXCHANGE SURFACE AND ICE-MAKING MACHINE INCORPORATING THE SAME |
摘要 |
<p>A sensor assembly for detecting ice crystal formation on a heat exchange surface in an ice-making machine comprises at least one microphone monitoring the sound made by a rotating blade assembly within the ice-making machine during ice slurry formation. A filter filters the output of the microphone to remove background noise. A comparator receives the output of the filter and compares the filtered microphone output with a threshold to determine if the filtered microphone output signifies ice crystal formation on the heat exchange surface. The operation of the ice-making machine can then be adjusted in a manner to allow the formed ice crystals to be removed from the heat exchange surface.</p> |
