Ice Cubes

Manually, ice is made by filling ice trays with water and placing them in the freezer compartment. With automatic refrigerator ice makers, we automate the process used to make ice manually. Instead of filling trays, water is piped into a tray in the freezer and the zero degree temperature freezes the water. The cubes are then dumped into an ice bucket.

However, with clear ice machines the ice making process* is substantially different. Water is sprayed onto a cold plate that is kept at 32 degrees Farenheit. Since water freezes at 32 degrees, the water freezes against the cold plate while chemicals and other contaminants fall off, leaving nothing but the clear cubes which are then dropped into the ice bin. The machine continues making ice until the bin is full.

The clear cubes consisting of healthy, pure water are always ready for use, and they never stick together or require breaking apart. That's because the ice bin is not a freezer compartment. The ice cubes are continuously melting and being replaced with new ice cubes. The resulting water is continuously sent out the drain. Depending on the brand and feature set that you select, some ice machines will also produce crushed ice, ice that is chewable, and even colored ice.

Crushed-Ice

Just as your refrigerator ice maker, clear ice machines have filters that regularly need replacing. In addition, they need to be cleaned every 6 months (varies with make and model).

*There are variations on this, but the end result is the same – the water is frozen in a clear condition without contaminants or air to make it cloudy.
