The first one is that the ice-making device produces ice flakes, and then the ice flakes are used as raw materials for making snow. The working flow is that water is first made into flake ice by an ice-making device, then the already made flake ice is crushed into powder by an ice crushing device, and finally the powdered ice crystals are sent out by an air conveying system. The system of making snow in this way is very complicated, and the quality of snow is far from that of natural snow.

The other is to use traditional high-pressure water and air to make snow. Its workflow is that high-pressure water from high-pressure water pump and high-pressure air from air compressor are mixed at double inlet nozzles. After the air leaves the nozzle, it takes away heat through natural evaporation and volume expansion, so that the droplets condense into ice crystals. However, the problem is that the smaller the water droplets, the greater the evaporation, the more water loss and the lower the snow-making efficiency. In addition, it can only work below freezing point, which is highly dependent on the external environment temperature and has low snow-making efficiency.
