What technology does the Winter Olympics use to make ice?

The whole ice-making process is roughly divided into several steps: making frozen bottom ice, spraying white, sealing white, drawing lines, sticking Logo, sealing lines and lifting water to make surface ice. Liu, the ice maker of Beijing Shougang Park Sports Center, said that first of all, pure water should be poured on the court, and the ice maker needs to spray water evenly on the court with a spray stick to ensure that it completely fits the cement floor.

When the water freezes to a certain temperature, it will be sprayed with white paint, which will turn the stadium into a familiar milky white;

After the white paint is fixed, stick logo and draw lines;

Then water is lifted to make surface ice, and finally the ice is polished and leveled by an ice sweeper, so that the ice making work is really completed.

"The change of meteorological factors is very important for our ice machine. We need to monitor the outdoor temperature and humidity in real time and adjust the state of the unit in time to maintain the stability of the skating rink.
