The requirements for flake ice machines include the following aspects:

Water temperature and quality: For use in fresh food areas, drinking water tested to national standards is required, and mechanical equipment needs to be thoroughly disinfected to ensure that the borneol is edible. 

The water temperature is generally around 16 degrees, and the ambient temperature is around 25 degrees.

Proper water temperature: The inlet water temperature is usually 0-45 degrees, and the ambient temperature can reach -30 degrees to 50 degrees, depending on the fresh food and the current environment.

Choose the appropriate refrigerant: The most common refrigerant on the market currently is R22, and some also use R404.

Specifications of flake ice: The specifications of flake ice suitable for supermarkets are 1.5-2.2 mm thick and the temperature of flake ice is between -5-8 degrees.

Flake ice quality: It should maintain lower temperatures and higher efficiency. Ice machines should be serviced and maintained regularly to ensure the quality of the ice flakes.

Flake ice machine Operation safety: You need to pay attention to safety when using the flake ice machine. You should operate it in accordance with the instructions and perform regular maintenance and repairs.
