On August 16th, a video of an ice sculpture experiment on the Internet caught the attention of netizens. The video showed that the ice hockey was frozen to shape in the Haier feast refrigerator. After 7 days, the ice sculpture master took it out and carved it into crystal ice cubes in a short time. After careful observation and comparison, people found that the ice crystals carved by the ice sculptures are the same as the real crystals. The surface is smooth and crystal clear. It is reported that the ice hockey can be carved into a crystal-like texture, and the original Haier feast refrigerator Intelligent constant temperature freezing and preservation technology is closely related.
Preservation technology into the watershed of the refrigerator industry
A few years ago, domestic refrigerators were still in the air-cooled, multi-door, frequency conversion and other aspects, so that they tried their best to compete for the refrigerator stock market. But in 2018, the refrigerator industry has seen a new development trend. Aowei Cloud Network (AVC) Yan Dongmin, senior research manager of the Ice Wash Division, said in an interview that the refrigerator door has rapidly changed from homogenization to homogenization, and it is difficult to innovate on the door; and various technologies such as air cooling and frequency conversion have been rapidly promoted. , popularization, in this context, preservation technology will become the next watershed in the refrigerator industry.
The wording of continuous warming is becoming the key word of the industry. The company has successively released new refrigerator preservation technology. According to the refrigerator ZDC report in the first half of 2018, in this fresh-keeping technology war, many innovations and upgrades of many refrigerator enterprises are innovative and upgraded. Concentrated in the cold room, and ignored the exploration of the freezer preservation technology. Zhongyikang data shows that as of the 32nd week, the overall retail sales of the refrigerator industry showed a negative growth, with an increase of -1.9%.
In this market context, Haier Refrigerator achieved a contrarian growth of 11.1% based on technological innovation, with a market share of 35.1%. Its original intelligent thermostat technology, with a freezer fan shield between the rear cover and the front of the frozen air duct. The stepping motor drives the gear shaft to open and close it, which reduces the temperature fluctuation of the freezer compartment by 45%. This solves the problem that the air duct of the freezer compartment of the air-cooled refrigerator cannot be closed, which is easy to cause temperature fluctuation of 10 °C, avoiding the density of the ice hockey. The temperature fluctuates and becomes larger, and there is expansion and extrusion, rupture and deformation, and finally crystal ice is produced.
Original technology meets users' frozen storage needs
It is understood that the Haier banquet refrigerator produces crystal ice cubes, which simulates the freezing effect of the ingredients in the refrigerator. When the ingredients are frozen, the Haier banquet refrigerator relies on intelligent constant temperature technology to create a constant temperature and freezing environment for the ingredients to ensure the ingredients. The cells, like frozen ice hockey, will not rupture, effectively maintain the nutritional value of the ingredients, and provide users with a freezer storage experience. In addition, Haier banquet refrigerator freezer uses fine control micro-channel technology, dry and wet storage technology, regulate refrigerator temperature and humidity , to ensure that the refrigerator and fruit and vegetable ingredients are fresh as ever, dry goods do not return to moisture.
On the contrary, when there is temperature fluctuation above 10 °C inside the refrigerator, the internal cell moisture of the meat ingredients will be freeze-thawed repeatedly, and the volume will increase. The larger the ice crystal will further squeeze the cells, causing the cells to deform or even rupture, resulting in irreversible Mechanical damage - the loss of nutrients such as protein. The loss of nutrients in meat ingredients will further lead to its decline in water holding capacity, drying out, and taste when it is eaten.
The birth of Haier Intelligent Thermostat Technology originates from the user's need for freezing and fresh-keeping. Users often complain that the meat in the refrigerator has been whitish for a long time, and the hair is dried. The Chinese New Year dumplings are frozen in the refrigerator for a long time... After capturing this demand, Haier Japan R&D Center integrated resources from Qingdao, Southeast Asia and other countries for global research, and finally determined the research and development direction of intelligent thermostat technology, and developed it in 16 months, from research and development to mass production. After one year of verification, the preservation of the freezer was finally realized.
