Pure water is pure water that can be directly consumed. Because of its convenience and speed, all kinds of bottles (barrels) filled with pure water have entered thousands of households. However, according to the monitoring situation, microbial exceeding the standard has become the main reason affecting the quality of its products. How to control microbial pollution has become an urgent problem to be solved in front of all production and business units and health supervision departments.
Ms. Mao Shan, manager of Shanghai Kangjiu Disinfection Technology Co., Ltd., specializing in R&D and equipment manufacturing of food sterilization technology, believes that in order to improve the safety of pure water filling and the implementation of QS food quality and safety market access system, such food enterprises must be built without Dust aseptic clean workshop, "dust-free" can be obtained by means of high-efficiency circulating filtration in junior high school; "sterile" through raw water and sterilization, air environment uninterrupted, equipment cleaning and sterilization, empty bottles (barrels) And a series of system engineering such as disinfection of the cap and sterilization protection of the operator to achieve the sterility of the finished water.
The water production process of the pure water plant is basically similar, that is, tap water (or deep well water) → mechanical filtration → precision filtration → electrodialysis, ultrafiltration (or reverse osmosis or secondary reverse osmosis) → finished water (ozone or ultraviolet disinfection) → irrigation The filling process is generally washing, disinfecting, rinsing, filling, capping, labeling, packaging, packaging, manual, simple mechanical, fully automatic three kinds. The relatively simple process has the threshold of QS access. The relevant national functional departments stipulate that the cleaning and filling workshops must have air purification devices and air disinfection facilities. The air cleanliness level ranges from 10,000 to 100, and the entrance to the filling room. All have air shower facilities, and the equipment and pipelines are disinfected using CIP decontamination system, which invisibly increases the investment operation cost.
So, how is the air environment disinfected by pure water during the production process? Ms. Mao Shan, manager of Shanghai Kangjiu Disinfection Technology Co., Ltd. said: It is recommended to use “white†plus “black†to carry out environmental disinfection. The so-called white means: workers use NICOLER dynamic technology sterilization when they go to work, and NICOLER dynamic sterilization equipment can work in some cases. The next synchronization sterilizes the inoculation chamber and is harmless to the human body. It is a disinfection technology that has been widely used in recent years. The principle of sterilization and disinfection is: the special pulse signal causes the nuclear resistance of the NICOLER cavity to generate a large number of sterilization factors, and the whole The sterilization process takes only 0.1 seconds to keep the environment in the production plant relatively sterilized. When disinfecting the workshop, people can work in the workshop at the same time, without any harm to the human body. Therefore, NICOLER dynamic technology is also called “food dynamic sterilization machineâ€. The so-called black means: at night, workers use static disinfection equipment after work, such as ozone, ultraviolet light and other sterilization measures, to kill bacteria in the environment and on the surface of the object, to prevent bacteria from breeding and multiplying when workers do not go to work, and the smell of ozone can be Effectively drive away the pests and worms, effectively reduce the harm of biological water to pure water filling. It should be noted that whether ozone or ultraviolet light is harmful to the human body, it needs to be turned on after the workers get off work, turn off before going to work, and then open the doors and windows for ventilation. After the NICOLER dynamic sterilizer, workers can enter the workshop.
At the same time, all enterprises should establish a sound and realistic health management system, especially for the important aspects of microbial contamination in the production process of pure water must be specifically in place to ensure operability, and do not disinfect the air in the production workshop. In the form, strictly in accordance with the disinfection specifications to ensure the sanitary quality of pure water.
