Can purification project effectively solve food safety problems? In depth analysis: how to effectively solve food safety problems in purification project
For food and medicine, the main culprit is microorganism, bacteria and other pollutants, while the design of ED purification engineering in the purification workshop of food factory can effectively solve the root cause and achieve the purpose of food purification through the following three ways.
1. In the purification workshop of the food factory, good ventilation effect shall be maintained. The standard design of the purification workshop of the food factory can keep the positive pressure state all the time, so as to prevent the entry of the external non clean air. It is also necessary to control the air flow correctly, which can effectively reduce the air pollution in the workshop.
2. In order to meet the production needs of products, it is necessary to maintain the cleanliness of the workshop, which is related to the number of air changes. The air change times in the purification workshop of the food factory shall be more than 15 times per hour.
3. Filter the air through primary, medium and high efficiency filters, which can effectively remove dust, bacteria and other harmful substances suspended in the air.
To control the pollution in the workshop, it is necessary to know where the pollution comes from. The pollution source in the workshop of the food factory:
I. people
According to the research, people are the biggest pollution source of clean room, accounting for about 90%. Generally, more than 1000 bacteria containing particles are emitted to the surrounding area by men per minute, and more than 750 bacteria containing particles are emitted by women, and the amount of dust generated by walking is larger. Therefore, before entering the purification workshop of the food factory, the production personnel should do bath cleaning, change clean work clothes, air shower room and shower, and strictly control the number of production personnel and activities in the purification workshop. Walkie talkies must be provided to reduce personnel movement.
Two, machinery
During the operation of the machine, due to the friction and other functions, some particles will also be produced. Therefore, it is necessary to ensure that the machinery and equipment in the purification workshop of the food factory are in a clean state at any time. The external equipment sent to the workshop shall be clean and qualified to ensure that no dust particles are brought into the medical purification workshop.
Three. Materials
It mainly includes processing and production materials, packaging boxes, etc. used in food and pharmaceutical workshops. There are two main purification methods: one is that the materials must be purified and reach the corresponding cleanliness between entering the workshop; the other is to use materials that do not generate dust, such as using dust-free paper. In addition, a reasonable material transportation route should be set up to avoid cross contamination of logistics.
Four, method
Improper operation will increase the amount of dust. The tooling in the workshop must avoid the friction between the metals, arrange the processes less, and move out the processes that do not need to be completed in the workshop as far as possible; the processes in the workshop must be arranged reasonably without blocking the air outlet, and the processes that are easy to generate dust particles are close to the air outlet.
Five, environment
Adopt decoration materials and medical purification equipment that do not produce dust, do not dust and are easy to clean. Clean the workshop regularly, test regularly, understand the control situation of the purification workshop of the food factory at any time, and solve the problems in time if found
