Abstract
An ice making machine includes a cooling vessel arranged to store an amount of liquid cooling medium and an amount of separation medium located above the cooling medium. A refrigeration mechanism is provided for refrigerating both the mediums in the cooling vessel, and a water supply system is provided for supplying fresh water in the form of water drops into the liquid cooling medium. The water drops are formed into ice balls while rising in the liquid cooling medium, and the formed ice balls are separated from the liquid cooling medium in the separation medium to be harvested. In this ice making machine, mercury is used as the liquid cooling medium, and hydrophobic liquid is used as the separation medium. The melting point of the separation medium is lower than that of the formed ice balls and the specific gravity of the separation medium is more than the formed ice balls and less than the mercury.
