If, by contrast, the immersion elements are too cold during or immediately after immersion in the water tank, a cloudy ice layer forms immediately upon contact of the water with the immersion elements on the surface thereof, which even after complete immersion. permanent wetting of the immersion elements can no longer melt with the water and remains visible as cloudiness in the ice pieces.
  • the immersion elements are too warm during or immediately after immersion in the water tank, the water is cooled too slowly around the ice fingers, so that it can lead to significant hypothermia of the water without the formation of ice begins.
  • the formation of ice or a crystallization then begins after some time abruptly and it forms cloudy pieces of ice.
  • the ice crystallization must therefore not run too fast even under favorable starting conditions. If a critical growth rate is exceeded, the crystal lattice of the ice crystal can no longer form clear ice, because it leads to inclusions and lattice defects, which lead to cloudy ice.
  • thermoelectric ice piece preparator for example, an ice finger assembly having immersion elements can be immersed in a container with water, ie a water tank filled with water. On the individual fingers, the water freezes and pieces of ice grow. If the pieces of ice have reached a sufficient size, the ice fingers can be removed from the water or the water pan can be removed. By subsequently heating up the ice finger assembly, the pieces of ice dissolve away from the ice fingers. Subsequently, further ice pieces can be produced again.
  • the ice cubes are prepared on cooled immersion elements or ice fingers dipped in water.
