Ice makers can be divided into commercial ice makers, household ice makers and industrial ice makers.

Ice making machines are divided from the shape of ice: granular ice (cylindrical, square, moon), snowflake, flake ice, plate ice, tube ice, and newly developed spherical ice.

Granular ice can be divided into spray type, flow type and immersion type according to the ice making method.

Cylindrical ice is generally spray ice making, which has low freezing point and can reach below minus 20 ℃. The contact surface between cylindrical surfaces is small, it is not easy to stick together, and it is convenient to use ice. Cylindrical ice has high hardness, low temperature and crystal clear ice. It is suitable for the cooling of foreign wine. The slow melting speed will not dilute the foreign wine and affect the taste of foreign wine. The disadvantage of cylindrical ice ice maker is that the ice production efficiency is relatively low. It is generally used to produce bar table small ice maker.

The temperature of flake ice is - 6 ℃ ~ - 12 ℃, which is most suitable for industrial processing and transportation of perishable goods. It is often used for seafood display at the fresh table of supermarkets. Large scale ice can also be used in cement plants, chemical plants, meat factories, marine fisheries, etc.

Refrigeration methods can be divided into: water-cooled ice maker and air-cooled ice maker.
