Aucma redefines the domestic freezer - 40 ℃ frost free freezer first

Article source:Aucma redefines the domestic freezer - 40 ℃ frost free freezer first  Hits:768  Release time:2017-12-14

On September 22, 2017, "aucma-40 ℃ frost free freezer and refrigerator new product launch conference" was grandly released on the first day of China International Consumer Electronics Expo. Among them, seven air-cooled frost free refrigerators have been launched, covering a full range of products from household to commercial use, realizing full coverage from 100-400 liter volume section, declaring the true arrival of the "frost free era" of refrigerators.

 

The air-cooled frost free freezer perfectly solves the problem of frosting that has plagued the industry for many years. This is another milestone change in the history of the development of okma's freezer, which is based on the introduction of - 40 ℃ deep cooling and quick freezing freezer and 0.1 ℃ precise temperature control intelligent cooler.

Refrigerators really enter the "real frost free era"

In the 20 years since the freezer entered the Chinese consumer market, with the continuous improvement of consumers' living standards, the function of the freezer is still stagnant in the direct cooling system, and the food materials are not fully frozen and frosted, which has become a "natural" disease of the freezer, especially the problems such as increased power consumption, food smell, bacterial proliferation, poor preservation effect, etc. caused by the frosting of the freezer, making "no frost" a part of the market A strong demand.



Focusing on the causes of frost formation in the freezer, the R & D team of Aucma freezer, through multiple technological innovations such as compound return air system, air curtain locking technology, strong multi effect defrosting system, launched the all air cooled frost free freezer, which perfectly solved the century's problem of frost formation in the freezer that has plagued the industry for many years.



The main reason for the frosting of the refrigerator is that the moisture in the interior of the cabinet evaporates and condenses when it is cold. The R & D Engineer of Aucma has repeatedly experimented and corrected, and launched a multiple compound return air system. Through the eddy current variable-frequency fan, a multidimensional three-dimensional air cooling cycle has been formed in the interior of the cabinet. The air-conditioning is quickly and evenly surrounded, 360 ° without dead angle, and the moisture in the cabinet is brought out of the cabinet in time, and the refrigerator operates without frost. In addition, the specially designed composite air duct basket not only facilitates the classified storage of food materials, but also further reduces the blocking risk of the return air to the lowest level, ensuring the smooth circulation of the air conditioner in the box.



In view of the problem that the outside air enters the box and frosts when it is cold, the frost free freezer innovates the technology of "air curtain locking". Through the professional and precise air duct design, the cold air can circulate continuously on the top of the freezer to form a strong cold air curtain, which greatly reduces the air entering the outside of the switch box and the loss of the cooling capacity in the box, locks the cooling, saves energy and keeps fresh.



For the defrosting problem of traditional freezer, "adaptive intelligent defrosting technology" is applied to the air-cooled frost free freezer at - 40 ℃. The intelligent defrosting system is divided into time, temperature and multi dimension. It can enter the intelligent defrosting program adaptively according to the amount of refrigeration load, frost layer thickness, frequency of opening the door and the accumulated running time of compression. Through scientific defrosting process and time sequence distribution, it can ensure that Under the condition that the temperature in the box is basically stable, the humidity in the box is constant, intelligent control and high-efficiency defrosting.


For the internal temperature of the box fluctuates greatly, the preservation effect is poor. -The 40 ℃ air-cooled frost free freezer applies the 0.1 ℃ precise temperature control and fresh-keeping technology. The inside of the cabinet is arranged in three layers, each layer is arranged with multiple points to track the temperature detection, and the wind speed is accurately adjusted, so that the distribution of the air-conditioning cycle is more uniform. The temperature fluctuation in the cabinet is controlled within 1 degree, and the temperature uniformity is 3 times higher than that of the traditional freezer. It can avoid the water loss caused by the big temperature fluctuation, guarantee the freshness of the food and prolong the shelf life of the food.


As a - 40 ℃ freezer, the new freezer also better solves the problem that the traditional freezer can't freeze and keep fresh the high-end ingredients such as salmon, tuna, all kinds of deep sea seafood, and realizes that the frozen shrimp can't be blackheaded, the crab meat can't be q-shaped, and the dumpling can't break its skin, so as to maximize the preservation of the nutrition of the ingredients. At the same time, the freezer is equipped with an exclusive patented nano silver ion antibacterial technology, which can inhibit 650 kinds of harmful bacteria, kill 99.9% of the bacteria, and effectively ensure the safety and health of food materials.


Refrigerator iteration meets a gap, and technological innovation opens a new era of refrigerator


As a product of modern industrial civilization, the birth of freezer has brought people into a real era of food cold storage. However, since the freezer was born nearly a hundred years ago, with the gradual improvement of people's living standards and health awareness, especially with the introduction of high-end ingredients such as salmon, tuna, deep sea fish, French foie gras, black truffle and other high-end ingredients into the household consumption market as representatives, the performance of the freezer has been challenged, such as the deep cold quick freezing, accurate temperature control, air-cooled frost free and other technical gaps that traditional freezers need to cross 。



In 2015, the - 40 ℃ deep freezing freezer was born in Aucma. The low-temperature storage of household refrigerators has evolved to about - 25 ℃, which is enough for the storage of common food materials. However, the storage of high-end food materials such as salmon (- below 30 ℃) has become an insurmountable gap. Aucma R & D team tried to apply ultra-low temperature, precise temperature control, rapid cooling and other technologies to household refrigeration products, and successfully developed the first domestic "- 40 ℃ deep cold quick-frozen freezer", which is extremely cold with one key, as low as - 40 ℃, so that food materials can quickly pass through the "maximum ice crystal generation zone", avoiding the nutrient loss caused by ice crystal piercing cells, and preserving the nutrition of food materials to the maximum extent, It really brings the refrigerator into a new world of low temperature. Frozen fish can revive (under laboratory conditions), frozen shrimp is not black headed, crab meat is more q-shaped, dumplings are not broken skin, etc. it has also become a typical application of deep cold quick-frozen freezer.



Master accurate temperature control, in 2016, 0.1 ℃ accurate temperature control freezer was born. The temperature range of traditional freezer is basically 1 ℃, and the temperature in the freezer will have an error of ± 2.5 ℃ during the storage process, which can meet the needs of daily household use. However, for high-end ingredients such as tuna, truffle, French foie gras, more accurate temperature control is required. Aucma upgraded and launched "Zhiku freezer" on the basis of deep cold and quick-frozen freezer. The temperature in the freezer is precisely controlled to 0.1 ℃ by national patent technology, and the temperature change in the freezer is only ± 0.1 ℃ error, making the fresh-keeping enter the era of accurate temperature control, and making the cold storage of food materials to the extreme.


Complete defrosting. Today, the wind is cold and frost freeSince the birth of freezer, frosting is a persistent disease. Frosting not only enhances the complexity of manual defrosting, but also brings many problems such as increased power consumption, poor fresh-keeping effect of food materials and so on. On the basis of deep cooling, quick freezing and accurate temperature control, Aucma R & D team once again conducted public relations research and development. Today, it finally launched - 40 ℃ air-cooled frost free freezer, truly bringing the freezer into the frost free world.


For a long time, Aucma has adhered to the innovation driven development strategy, built a user-centered technology innovation model integrating market, R & D and production, and effectively promoted the leapfrog development of industry technology. Whether it is - 40 ℃ deep freezing freezer, Zhiku freezer, or - 40 ℃ air-cooled frost free freezer, the evolution of the three generations of freezers, all take the user's pain point as the starting point or foothold of research and development, and realize the deep fit of product functions and user needs.
