Editor's note：There is such a young man. 15 years ago, he started to work with artificial snowmaking soon after he graduated from college. In order to create a perfect artificial snowfall, he started from scratch and spent 15 years studying it. During the period, I experienced various failures and challenges, but finally overcome all kinds of unimaginable difficulties with my tenacious will. After 15 years of grinding a sword, I finally marveled at the world's indoor snowmaking strength. He proved that the Chinese can have their own indoor artificial snow black technology. This is the experience of Li Zixin, the founder of Mingxing Bingxue, and the journey of the protagonist of this article and the “first person” of Chinese indoor snowmaking experts.
When Wu Yanlong, the first person in China's cross-country skiing and the director of the Winter Sports Professional Committee of the Heilongjiang Provincial Sports Federation, first entered the Jilin Beishan Indoor Four Seasons Cross-country Ski Resort, it was instantly shocked by the sights.
Up to 1321m indoor ski tunnel, professional cross-country ski trail design, reasonable tunnel interior layout, and even the oxygen content in the tunnel is very comfortable. But for professional athletes like him, this is not enough, because there is a more professional consideration that will be crucial for the athlete's final training and performance - that is, snow quality.
After some "armed" field experience, Wu Yanlong was most surprised and excited that the snow in the snow cave is sand-like dry snow, and the snow quality is completely comparable to the snow quality in the real game. "The whole skiing process The movement is very smooth, the speed is relatively fast, and the facilities are very professional. It provides protection for the strength of China's cross-country skiing in many aspects."

Such indoor artificial snow and snow quality is completely blank for Chinese technology more than a decade ago. A fictitious coincidence fifteen years ago, Li Zixin, the founder of Mingxing Bingxue, entered this field and set up a team from scratch. After a lot of trials and improvements, he finally developed and successfully developed the "Xingxing" with independent intellectual property rights. Ice and snow indoor distributed snowmaking system, and successfully implemented in many world-class projects such as Jilin Beishan Indoor Four Seasons Cross-country Ski Resort and Harbin Sunshine Snow World, and set a number of indoor snowmaking world records, which can be described as Chinese indoors. The "first person" of snowmaking technology.

As the special training base for the winter skiing team of the national ski team and the national key project for winter Olympics, the Beibei indoor four-season cross-country ski resort in Jilin has received much attention since the launch. The project was jointly built by the State Sports General Administration in conjunction with Jilin Province and Jilin City. During the period, General Secretary Xi Jinping twice personally approved. At present, the base has been officially put into use. In addition to the Chinese national team, a number of national teams have also settled in the ski resort for professional training in cross-country skiing, biathlon, and Nordic projects. The venue is excellent in facilities and perfect. The snow quality has been well received by professional athletes and coaches from all over the world.
Indoor artificial snow making, how difficult is it to form the perfect snow quality that is comparable to nature? Xiaobian held the "breaking the casserole to ask the end" mood, specially interviewed Li. As a veteran expert in domestic indoor snowmaking technology, Mr. Li personally led the team to carry out the demonstration and implementation of dozens of projects, large and small, and participated in the formulation of technical standards for indoor ski resort industry and several national major project laboratories ( Equipment and technical services, including the National High Speed Rail Ice and Snow Laboratory and the 冰20 fighter ice and snow laboratory.

It is reported that the Mingxing Ice and Snow Indoor Distributed Snowmaking System mimics the formation process of natural snow, and its snow quality reaches powdery snow, ensuring the best skiing experience for skiers. Among them, the nuclear device is the core technology of the snow machine. First, the high-pressure air generated by the compressor is sent to the nozzle of the nuclear generator, and then the fan is responsible for blowing the atomized water mist into the air, and the nuclear device generates a snow core after the air and water form a certain ratio, and the snow core is Cold in the air forms snow. Before the snow is made, the controller will be set to the intelligent adjustable working state through the control of the automation software. During the formation of snow, the system can automatically analyze the quality, appearance and humidity of the snow core, and improve the quality and efficiency of snowmaking by adjusting the ratio of air to water. When the snow quality is at its best, the system will remain stable in this state, ensuring continuous output of the best snow quality, while having a very high snowmaking efficiency.
Usually, outdoor artificial snowmaking is basically “depending on the sky” – as long as the outdoor temperature, humidity, and no precipitation disturbances are met, snowmaking can be achieved. In contrast, indoor snowmaking requires the simulation of a “natural condition” suitable for artificial snowmaking in a relatively closed indoor environment, so the investment and technical difficulty of indoor ski resorts is much higher than that of outdoor ski resorts.

The composition of the indoor snowmaking system is extremely complicated. It is the integration of tens of thousands of components in the six systems of refrigeration system, snowfall system, dehumidification system, fresh air system, automatic control system and thermal insulation system, and it is indispensable to create perfect snow quality. To make the approach to natural powder snow, the control of the snowmaking process is very critical, which also directly reflects the comprehensive ability of an enterprise in the overall design, equipment manufacturing, project implementation and operation and maintenance, and also test an indoor ski resort. The most direct and even the most critical indicator of a snow equipment or system.
The Harbin Sunshine Snow World, which is certified by the Guinness World Record for Largest Indoor Skiing Facilities, is another classic case of Mingxing Ice and Snow. Its ice and snow process system design, equipment supply, engineering and technical services are all exclusively completed by Mingxing Bingxue. The venue has been in operation for nearly two years. The snow field is suitable for skiing because of the choice of snow trails, and the snow is completely comparable to natural snow (dry snow and powder snow), which is favored by the majority of ski professionals and enthusiasts.

In addition, due to the national hardware standards and snow conditions, including double-plate alpine skiing, freestyle skiing, mogul, slope obstacles and parallel rotation, BigAir and other skiing projects, As the designated training base of the national ski team, the National Sports General Administration, Heilongjiang Snow Training Center, Changping Jundushan Youth Ski Team, Beijing Haidian Ski Team, Liaoning Winter Sports Project Management Center and other national skiers perform professional training here.

"As a national independent brand, we have the opportunity to serve the Winter Olympics. We will make our own contribution to help the Winter Olympics athletes prepare for the full 2022. This is the pride and pride of all of our Mingxing people. As the global leader in indoor snowmaking technology, We will continue to respond to the national call, focusing on independent research and development and innovation of snowmaking technology, contributing to 'China's wisdom creation' and serving the world's ice and snow enthusiasts," Li Zixin said frankly. As of today, Mingxing Bingxue's "indoor distributed snowmaking system" market share exceeds 85%. Compared with similar products in the market, the production cost of this system can be saved by 50%, and the electricity cost per cubic meter can be saved by 27%, which greatly reduces the investment cost of customers.
The ultimate pursuit of snow quality, aptly explains the craftsmanship of Mingxing Ice and Snow for product and technology excellence. In the heart of technology to serve the country, Li Zixin's greatest vision is to improve customer efficiency and help China's ice and snow industry to the world with innovative, energy-saving, efficient and cost-effective products and services.
"The road is long and it’s a long way to go. I will go up and down." The ice and snow industry is in the ascendant, and there is much to be done. Mingxing Ice and Snow will not forget the original heart, and move forward with the "snow" as the way to embrace the most beautiful poems and distant places.
