On June 17, the Shenzhou-12 manned spacecraft was successfully launched and later docked with the Tianhe core module. Three astronauts were successfully stationed in the Tianhe core module, marking China’s first entry into its own space station. What interests extensive people is how Chinese astronauts will get fed over the next three months.
It is reported that there are more than 120 kinds of aerospace food for astronauts’ daily meals in space station in spite of the long distance. Unprecedentedly, the first aerospace microwave oven is also available to astronauts for abundant and nutritious food.
The Tianzhou-2 cargo spacecraft of China’s space station was launched on the evening of May 29 at Wenchang Space Launch Center in Hainan. It carries the world first aerospace microwave oven developed by Galanz so as to provide healthy food for astronauts in the core module of the space station.
Microwave oven has long been one of the most common home appliances, however, it has taken beyond 70 years for all humankind to send microwave oven to space. Owing to Galanz aerospace microwave oven’s application to China’s space station, China has become the first country to allow astronauts to eat healthy and delicious hot meals in space. Astronauts can easily cook various food on the station in accordance with appetites and seasons.
It is understood that the aerospace microwave oven is required to withstand high-frequency turbulence during the rocket’s lift-off process and work for 10 years continuously in space environment with fast and even heating performance. In order to resolve these problems to achieve “cooking in space”, Galanz assembled a group of professionals to start the project in 2011 and finally succeeded in 2021. “Ten years’ diligence makes an aerospace microwave oven”.
The key to the success of the project lies primarily in the efficiency of the magnetron and the restructuring of the aerospace microwave oven. As the top-one brand of microwave oven, Galanz also leads the world in self-supporting core components of microwave oven. Upon R&D mission accepted, Galanz initiated its development of special magnetron. Meanwhile, through innovations in components and parts integration, Galanz has made the aerospace microwave oven achieve energy efficiency of super level I, and it can complete a staple meal for three astronauts in 7 minutes.
The space station has extremely strict restrictions on the specifications and weight of facilities and supplies. In order to reduce the volume of the microwave oven and meet the reliability requirements of space operations, Galanz R&D engineers have been working to optimize the product structure, improve the product’s mechanical strength, and creatively adopt innovative technologies such as fasteners and integral molding. Moreover, Galanz has also specially made a frequency conversion microwave power supply to replace the traditional high-voltage transformer, greatly reducing the weight of the product.
