Science and Technology Daily, Beijing, November 12 (Reporter Chen Yu) The reporter was informed on the 12th that the second-generation cold chain tunnel-type omnidirectional automatic disinfection system independently developed by Tongfang Weishi has arrived in Qingdao cold storage and started the disinfection operation trial.
According to Li Yuanjing, senior vice president of Tongfang Weishi, the system has been greatly improved in terms of accuracy, applicability, convenience and intelligence based on user feedback on site use.
In order to effectively prevent the risk of the new crown virus being imported through imported cold chain food, on November 9, the National Health Commission issued the "Notice on Issuing the Work Plan for Preventive and Comprehensive Disinfection of Imported Cold Chain Food."
The plan not only requires the realization of full-process closed-loop control and traceability, but also clarifies that before the first contact of imported cold chain food with people in China, preventive and comprehensive disinfection is required in the ports, transportation, warehousing, wholesale and retail links.
It is understood that as early as July this year, Tongfang Weishi quickly responded to the needs of Tianjin Customs and began the development of the first generation of cold chain tunnel-type all-round disinfection system.
In just one month, Tongfang Weishi completed the installation and commissioning of 10 sets of equipment at the Tianjin Port International Logistics Cold Chain Base and other 6 cold chain food companies and storage bases, and carried out sampling and elimination of imported cold chain food packaging.
The second-generation sterilization system can achieve precise sterilization of different microorganisms such as viruses and bacteria by adjusting the flow rate, wind speed, and transmission speed, and will not cause pollution to the package contents.
The equipment adopts the "automatic six-sided spraying and killing technology", whether it is cold chain goods, postal parcels or checked luggage, the disinfectant can be evenly sprayed on the outer surface of the object to achieve full disinfection without dead ends.
At the same time, the system can realize one-key conversion of import and export functions, which is convenient for two-way disinfection control.
The modular and integrated design of the overall structure can be flexibly used in different places such as ports and cold storage, and can be moved in a short distance to achieve docking with various logistics transportation systems to meet the requirements of different delivery methods for sterilization items.
In order to ensure the safety of personnel during the disinfection process, when Tongfang Weishi developed this product, the design of such as relatively closed spray space, automatic detection and replenishment of liquid level, self-recovery of waste liquid, and no spillage were designed to minimize irritating contact. risk.
At the same time, through 5G/4G communication technology to access the Internet, combined with Beidou/GPS positioning, the system can remotely monitor the location and use status of the equipment in real time, and can also access the user’s proprietary management system through multiple security authentication methods to receive and disinfect remotely Command and return disinfection data.
It is understood that, previously relying on the integration of industry-university-research and use of scientific and technological achievements transformation platform, Tongfang Weishi has launched infrared binocular temperature measurement camera, intelligent non-contact temperature measurement and security inspection integrated platform, epidemic prevention isolation unit, positive pressure protection non-contact nucleic acid sampling station, etc. Technology anti-epidemic products.
