Snow are able to grow to hundreds of micrometers or millimeters in size at the expense of the water droplets by the Wegener–Bergeron–Findeisen process. The corresponding depletion of water vapor causes the ice crystals to grow at the droplets' expense. These large crystals are an efficient source of precipitation, since they fall through the atmosphere due to their mass, and may collide and stick together in clusters, or aggregates. These aggregates are snowflakes, and are usually the type of ice particle that falls to the ground. Although the ice is clear, scattering of light by the crystal facets and hollows/imperfections mean
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
