Snow Snow Snow refers to forms of ice crystals that precipitate from the atmosphere (usually from clouds) and undergo changes on the Earth's surface. It pertains to frozen crystalline water throughout its life cycle, starting when, under suitable conditions, the ice crystals form in the atmosphere, increase to millimeter size, precipitate and accumulate on surfaces, then metamorphose in place, and ultimately melt, slide or sublimate away. Snowstorms organize and develop by feeding on sources of atmospheric moisture and cold air. Snowflakes nucleate around particles in the atmosphere by attracting supercooled water droplets, which freeze in hexagonal-shaped crystals. Snowflakes take on a
Pumpable ice technology main advantages in comparison with other freezing techniques are low energy expenditure and the possibility to tune the rate of the phase change from liquid to solid ice, which in turn increases the production of pure water ice crystals and simplifies the separation of concentrated juice or food liquid and ice crystals. In the 1990s, frozen carbonated beverages and frozen uncarbonated beverages began to enjoy great popularity. The manufacture (process and refrigeration equipment) of almost all frozen carbonated beverages and frozen uncarbonated beverages is organized like the production of pumpable ice. The frozen carbonated beverage machine was invented in the
