China's disinfection and sterilization technology leading Europe and America

Recently, 26 college students from Deyang's Xiaoquan Normal School in Sichuan Province diarrhea after eating in the cafeteria and stayed in the hospital. Deyang City Liyang District CDC confirmed that the incident was food poisoning.

Li Xingmin, an associate professor at the College of Food Science and Nutritional Engineering at China Agricultural University, said that the total number of colonies or coliforms in food is the main indicator of health status. Excessive standards will not only affect the taste, but also other spoilage bacteria and even pathogenic bacteria. Exceeding the standard, causing poisoning.

It can be seen that food safety and hygiene runs through the entire production process, and advanced disinfection and sterilization technology and equipment are important means to ensure food hygiene and safety.

According to Xue Guangbo, a well-known disinfection and epidemiologist in China and director of the Department of Epidemiology at Shanghai Second Military Medical University, the disinfection and sterilization methods are mainly divided into physical sterilization, chemical sterilization and biological disinfection. At present, new disinfection and sterilization methods at home and abroad mainly include dibromohydantoin disinfectant, polyhexamethylene guanidine disinfectant, high-intensity ultraviolet sterilizer and bed unit sterilizer.

Physical sterilization methods include thermal sterilization, radiation sterilization, and plasma sterilization. Among them, the plasma sterilizer is a new type of sterilizing device, which uses a highly ionized gas cloud to act on a powerful electromagnetic field, so that the gas cloud contains charged particles, ions and uncharged molecules, excited atoms, and free radicals. And β-ray, ultraviolet light, etc., this mixed gas has a strong bactericidal effect.

The research on food disinfection and sterilization technology has been in China for a long time, and it has achieved good results in the fields of physical sterilization, chemical disinfection, and biological disinfection methods.

A successful research and development and application called NICOLER sterilization and disinfection technology (in the field of ion sterilization) fills the blank of domestic disinfection and sterilization technology, and its advanced level is far ahead of developed countries such as Europe and America.

The technology uses the principle of plasma sterilization, using the latest NICOLER three-stage bidirectional generating chamber, through the high-voltage DC pulse to make the plasma electrostatic field produce a reverse effect, generating a large amount of plasma. Under the action of the negative pressure fan, the polluted air in the air is drawn into the cavity, and the negatively charged bacteria are broken down when the cavity occurs through the NICOLER . The entire sterilization process takes only 0.1 seconds, and the components such as the drug-impregnated activated carbon are combined for the second time. Sterilization and filtration, the treated clean air is circulated rapidly and rapidly, keeping the controlled environment in the "sterile dust-free" standard.

According to the food safety engineer Zhou legislation, the equipment manufactured by this technology is the first food-specific dynamic disinfection and sterilization equipment in China. It mainly solves the problem of sterilizing and disinfecting the workshop environment under the condition of some people working. The limitations of the original traditional sterilization and disinfection equipment are not synchronized.

After repeated tests showed that: open a "NICOLER Food dynamic disinfection machine" After 60 minutes, the workshop air settlement bacteria ≤ 15 CFU / dish • 30 minutes 45 square meters of packaging occasionally filling workshop, air planktonic bacteria ≤ 800 a / cubic meter of air cleanliness ≥ 30 Wan level in full compliance with corporate and national standards. At the same time, in order to meet the needs of various small and medium-sized food enterprises, the company also launched the NICOLER pipeline sterilizer, which can be customized for the air conditioning system and ventilation purification system installed or newly installed, which can adapt to different air volume. Air conditioning box.

It is understood that the current NICOLER dynamic disinfection and sterilization technology has been widely used in the packaging, cooling and filling of some large food enterprises. The person in charge of the marketing department of Shanghai Kangjiu Dynamic Sterilization Technology Co., Ltd. introduced that the food-specific dynamic disinfection and sterilization equipment manufactured by this technology has been exported to Europe, America, Russia, Vietnam, Nigeria and other countries to obtain consumer recognition.

Dr. Alston , who returned from studying in Germany , analyzed that in the future, NICOLER ionic sterilization technology will gain market leadership and the superiority of technology itself will gradually replace traditional sterilization methods.
