Only 5 seconds of irradiation is needed to complete the physical elimination, and the average daily delivery quantity is more than 10000 pieces! Fuzhou University has equipped a cold chain logistics UV catalytic composite killing machine in the campus Express Center to kill all express packages entering the campus and control the first gateway of campus logistics.
"As China's first photocatalytic equipment for killing cold chain virus, the equipment has been installed and deployed in 30 important scenes such as the Beijing Winter Olympic Games and the provincial cold chain supervision centralized warehouse, postal service, colleges and universities, hospitals and so on." On March 20, the relevant person in charge of Fujian Provincial Department of science and technology told the science and Technology Daily that at present, it is coordinating and organizing the disinfection effect evaluation test, providing scientific basis and operation guidance for the evaluation of disinfection effect, and accelerating the pace of popularization and application.
Make every effort to tackle key problems and ensure the first pass of cold chain logistics
It is reported that the killing machine is jointly developed by the academician Fu Xianzhi team of Fuzhou University and the Dr. Chen Jian team of Fuxia technology. It is also the only large-scale surface killing equipment approved to be used in the Beijing Winter Olympic Games. It has the effect of effectively killing covid-19 virus on the outer surface of cold chain food and logistics express. The killing rate of standard bacteria is more than 99.9%, and has no impact on human body and food. In addition, the cold storage of the canteen in the student living area of Fuzhou University is also equipped with the killing machine to kill the cold chain table, so as to ensure the first pass of food safety for the campus.
In Fujian, in addition to the cold chain logistics UV catalytic composite disinfection machine, a number of "hard core" anti epidemic scientific research achievements such as China's first set of "industrial electron beam cold chain virus disinfection equipment" and the country's first "ultra-high power deep UV LED portable disinfection instrument" have been released one after another. Among them, China's first set of "industrial grade electron beam cold chain virus killing equipment" has passed the acceptance of experts from China Center for Disease Control and prevention. It can disinfect and sterilize pathogenic microorganisms on the surface of cold chain logistics packaging as soon as 1 second, and the killing efficiency is greater than 99.99%; It can be used for transportation and preservation of frozen Shenzhen Agricultural Products Group Co.Ltd(000061) , aquatic products, medical devices, aerospace equipment, logistics and packaging, etc. The first "ultra-high power deep UV LED portable disinfector" in China has an instant killing effect on covid-19 virus, and the inactivation rate is 99.93%. It has been applied in the cold chain logistics industry, subway bus, taxi and other fields in the province.
After the outbreak of covid-19 pneumonia, Fujian Provincial Department of science and technology, relying on the social development science and technology division of the Department, established a special class for scientific research in the whole province, organized and coordinated the advantageous scientific research forces in the whole province, and coordinated the scientific research in epidemic prevention and control. Over the past two years, the special class for scientific research has adhered to the principle of "urgent need of the epidemic and short-term results" and "research first and then project approval", opened up a "green channel" for scientific research, and started to implement about 30 emergency scientific research projects focusing on clinical diagnosis and treatment technology, vaccines and drugs, testing products, cold chain killing equipment, etc., with a total allocation of more than 31 million yuan. Through the joint efforts of all units and departments, the province's scientific research on epidemic prevention and control has achieved remarkable results, and a number of scientific and technological achievements have played an important role in national and provincial epidemic prevention and control.
Strengthen the landing and add more scientific and technological tools for epidemic prevention and control
At present, Fujian Province is launching a series of measures for the implementation and transformation of scientific and technological achievements, strengthening the cultivation of covid-19 virus killing industry such as ultraviolet catalytic killing machine, focusing on supporting a number of leading enterprises, striving to make the killing industry bigger and stronger and help the high-quality development of economy and society. For example, the promotion and docking meeting of scientific research achievements in epidemic prevention and control and the road show of torch scientific and technological achievements through train (Fujian station) of the Ministry of science and technology - special session of biomedicine and medical devices were held, with a total of 134 achievements promoted and 15 on-site contracts signed; The group participated in Hainan International Health Industry Expo and China International Medical and Health Industry Summit Forum, promoted 106 scientific research achievements, intensively displayed 30, and reached docking intentions with 7 enterprise customers from other provinces; Participated in the 23rd China International High Tech Fair Online, promoted 30 scientific research achievements, and Fuxia technology's "ultraviolet catalytic composite killing machine" won the excellent product award issued by the organizing committee.
At the same time, Fujian has also accelerated the research on industrial standards of ultraviolet disinfection products or technologies, and promoted the national technical guide for covid-19 virus prevention, control and disinfection in the production and operation process of cold chain food (Second Edition) to add relevant contents of physical disinfection technology; Three items of equipment, including "conveyor belt ultraviolet disinfection machine", "cold chain inactivation intelligent equipment" and "virus killing system of centralized ozone killing warehouse in large cold storage", were listed in the guidance catalogue for the promotion and application of the first (set) major technical equipment in Fujian Province (2021 Edition); Siasun Robot&Automation Co.Ltd(300024) products, such as "Xiao Xiao Bao" and "Xiao Xiao Xin", developed by Fujian smart cloud Technology Co., Ltd., have the functions of mobile temperature measurement, epidemic prevention supervision, automatic spray killing and so on. They have been applied in venues such as Winter Olympic Games, airports, hospitals and so on.
"Comprehensively accelerate the scientific research on epidemic prevention and control, strive to add more scientific and technological 'sharp tools' and contribute more scientific and technological strength to epidemic prevention and control." The relevant person in charge of Fujian Provincial Department of science and technology said that he would seriously study and implement the spirit of the important speech made by Xi Jinping general secretary at the Standing Committee of the Political Bureau of the CPC Central Committee on March 17, and continue to track and fully serve the approved projects such as vaccine research and development, drugs, diagnosis and treatment, rapid detection and cold chain killing equipment in accordance with the decisions, deployment and requirements of the provincial Party committee and the provincial government, so as to speed up the research and development progress and market-oriented promotion and application. At the same time, timely track the latest situation and scientific research trends of epidemic prevention and control outside China, pay close attention to domestic self-test technologies and products such as covid-19 virus antigen detection reagent and oral drugs, and then start a new round of epidemic prevention and control scientific research projects, so as to strive to develop more scientific and technological "sharp tools" for epidemic prevention and control in the whole province and even the whole country. In addition, in the decision on Commending the advanced collectives and individuals of the national science and technology system in combating covid-19 pneumonia recently issued by the Ministry of science and technology, five collectives including the social development science and Technology Department of Fujian Provincial Department of science and technology and six individuals including Dr. Chen Jian of Fuxia science and technology were selected.
