Flake ice
Flake (engl. Flake ice ) is an engineered form of ice . Flake ice consists of individual flakes with an irregular, flake-like, slightly wavy shape. The ice flakes are 1 to 2 mm thick and have a temperature of around −7 ° C during manufacture.
use
Flake ice can be used to cool food, especially fish, or to produce food. The advantage of flake ice lies in the large, dry-frozen surface, over which an optimal heat exchange can take place, whereby rapid and efficient cooling is achieved.
Another area of application is the cooling of concrete.
Manufacturing
In the production of a flake ice water is filled into a cylindrical container, for example in which a stainless steel roller is located and the wall of which is cooled by a strong cooling machine. Ice forms on the cylinder wall, which comes up through a screw conveyor and is scraped off by a scraper and then falls into a storage container.
Another manufacturing process works with a horizontally arranged evaporator roller that rotates in a water bath. With every rotation, water freezes on the strongly cooled surface of the evaporator and flakes off on a scraper.
Flake ice machines can produce amounts of ice between 100 kg and several tons per day.
