摘要

A method for manufacturing single crystal ice by creating a temperature environment in which a top section of the refrigerating temperature distribution of a hermetically sealed refrigerating space is held to high temperature and a bottom section to low temperature, guiding water to the high-temperature section, and dripping droplets of the water to the low-temperature section.
