|発明の名称||SOLIDIFYING METHOD FOR LIQUID, ICE MAKING METHOD AND ICEMAKER|
PROBLEM TO BE SOLVED: To provide an ice making method and an icemaker 10 capable of continuously manufacturing monocrystalline ice of an optional shape with high hardness, high transparency, and a high commercial value.
SOLUTION: The icemaker 10 is characterized in that a periphery excluding an opening 13 of a vessel 12 filled with water 11 is covered by a heat insulating material 14, the opening 13 of the vessel 12 is covered with a vacuum tank 18, a low temperature heat source 12 of a freezing temperature or lower is provided on an outer surface of the vacuum tank 18 in an opposite side of the vessel 12, and the water 11 in the vessel 12 is frozen by radiation via the vacuum tank 18. A buffering vessel 17 communicating with an interior of the vessel 12 is provided, and a Peltier element is used as the low temperature heat source 21.
