The reporter recently learned from the China Astronaut Research and Training Center that space food is expected to enter the supermarket in the near future, and ordinary people can taste the food that the astronauts eat in space at any time.
Chen Bin, chief designer of the food and nutrition subsystem of the manned spaceflight astronaut system, introduced that space food is safe, nutritious, efficient, convenient, and diverse.
Due to the limited capacity and volume of the spacecraft and the special space environment, the advantages of aerospace foods such as high nutrition, high performance, and convenience are very prominent. Chen Bin said that if it is applied to civilian use, it will be welcomed in polar expeditions, mountaineering, tourism and other activities.
In addition, aerospace food adopts the most stringent food production standards in the world. It has near-rigorous standards from raw material selection, processing technology, and production process to the whole process of analysis and testing. For example, the requirements for air cleanliness of production workshops are the same as those for drug production. Chen Bin said that as food safety becomes more and more important, the advantages of aerospace foods in terms of safety will become more apparent.
“We have been committed to industrializing aerospace foods since 2006.†Chen Bin said that at present, they have cooperated with relevant companies, provided by the Astronaut Center with production technology, technology and quality standards, and cooperative enterprises provide production plants and equipment. Has produced chocolate and cake products.
Chen Bin said that in the future there will be more aerospace foods or foods that use aerospace food standards and processes into the supermarket. (Reporter Sun Yanxin, Bai Ruixue)
Non-tapping screws are machine Screw, the pieceworker to be fastened must be tapped with taps in the screw hole in advance to match the screw threads.
The difference between tooth screws and other screws depends on whether they can be used together with nuts. Tooth screws can be used with nuts. And relative to the screws of other teeth, there are self-tapping screws. The nut of this kind of screw has no bow teeth. As for the standard teeth and fine teeth are only different pitch, it is the nut of the machine screw
