The demand for various forms of ice, especially spherical ice, has experienced significant growth due to its unique appearance and consistent melting rate. However, the current methods of manufacturing spherical ice suffer from prolonged production times due to a low biotite number, as well as challenges with transparency and strength. In response to these limitations, this study introduces an approach to producing spherical ice, utilizing an expanding mold technique.

This method aims to optimize heat transfer through convection within a cooling device, facilitating the formation of small ice seeds. Subsequently, it expedites the ice creation process by regularly injecting water between the mold and the ice seeds, effectively reducing manufacturing time. By initiating ice formation from the surface, this approach ensures efficient cooling and further minimizes production duration.

Additionally, the proposed method promises to enhance ice clarity and strength. The mold's compressive and cooling effects contribute to these desirable characteristics. Our research endeavors to experimentally identify the optimal conditions for ice formation and explore the distinct features of various ice forms. This knowledge will pave the way for advancements in ice-making technology, offering users superior ice products that exceed their preferences and expectations.
