The first step in building food and medical cleanrooms, dust-free workshops, clean rooms, and purification rooms is site selection

Regarding the selection of clean room locations: The location should be kept at a distance of at least 25 meters from toxic, harmful places and other sources of pollution to ensure that it is not contaminated by pollution sources. The factory area does not allow the selection of areas that significantly contaminate food, and toxic waste, dust, toxic gases, radioactive substances, and other diffuse sources of pollution are not allowed in the surrounding area. Pollution sources refer to places where pathogenic microorganisms or other serious harmful pollutants may be generated, such as chemical plants, cement plants, stone plants, lime plants, smelters, hazardous chemicals, and other places with hidden dangers of dust, harmful gases, radioactive substances, and other diffuse pollution sources; Places for garbage collection, storage, transfer, and treatment; Slaughterhouse; Livestock and poultry farms, public toilets, and other places.

1. Maintain a clean production environment in the dust-free workshop, with no potential areas for the proliferation of pests or harmful waste, as well as no dust, harmful gases, radioactive substances, or other sources of diffuse pollution. When various sources of pollution are difficult to avoid, necessary preventive measures should be taken to effectively eliminate the impact caused by the pollution sources.
2. The layout of the clean room factory area is reasonable, and the functional areas are clearly divided. Maintain appropriate distance or separation between living and production areas to prevent cross contamination.

3. The roads in the factory area should be paved with hard materials, and there should be no dust or water accumulation in the factory area. The greening of the factory area should be kept at an appropriate distance from the production workshop, and the vegetation should be regularly maintained to prevent the breeding of pests.

4. Factory buildings and purification rooms: There should be factories and workshops that are suitable for the variety and quantity of products produced, and the work areas should be reasonably arranged and divided according to the requirements of production technology and cleanliness to avoid cross contamination; The inspection room set up in the factory should be separated from the production area!

5. The selection of production workshops for cleanrooms: Due to the many ventilation ducts and purification equipment in cleanrooms, there are certain requirements for the selection of cleanrooms, such as the floor height, the shortest part of the floor including obstacles must be sufficiently positioned to prevent ventilation ducts, and the size of the ventilation ducts needs to be calculated based on the required air volume In addition, there needs to be sufficient space to place purified air conditioners, which are divided into outdoor units and indoor clean air cabinets.

Return air duct for purification workshop (pay attention to the floor height when selecting the workshop)

Outdoor air conditioning unit (the factory building needs sufficient space to place the unit, and the placement location needs to be well ventilated)

Purification air conditioning room (in addition to the area required for production, a purification air conditioning room should also be reserved, and the size of the room should be designed according to the cooling capacity requirements)
