What are the requirements for the construction of a 100,000-level dust-free workshop in the food-grade SC standard?

According to the country's production license rules for food and beverages, the clean room environment of food and beverage workshops should be controlled to reach the air purification standard of 10,000 or 100,000 grades. In order to facilitate the design and sanitation management of different production areas, the clean room decoration of food factories is usually divided into non-food processing areas, general production areas, quasi-clean production areas and clean production areas according to the cleanliness of the pharmaceutical cleanroom. Quasi-clean production areas and clean production areas are controlled production areas. 1. SC certification requirements for 100,000-level purification projects in food workshops Clean room ISO level 7 level 2. General production area The general production area refers to the raw material warehouse, material warehouse, outer packaging room and finished product warehouse, etc., which are closely related to product production, but the cleanliness of the air in the area is inferior to the operation in the controlled production area. area. 3. Arrangement of production workshops and division of hygiene grades In order to facilitate the design and hygiene management of different production areas, food factory workshops are usually divided into non-food processing areas, general production areas, quasi-clean production areas and Clean production area. Quasi-clean production areas and clean production areas are controlled production areas. Fourth, the ground and walls 1. Ground: should have a drainage slope of 1%-2%. 2. Walls: In clean areas with relative humidity exceeding 80%, the walls should be coated with antibacterial and anti-mildew coatings, and the anti-bacterial and anti-mildew coatings should comply with 'HG/T 3950'. The limit of harmful substances in coatings shall comply with the provisions of 'GB 18582 Limits of Hazardous Substances in Interior Wall Coatings for Interior Decoration Materials'. 5. Quasi-clean production area Clean production area refers to the operation area whose cleanliness requirements are inferior to the clean production area, such as processing and conditioning fields. Including: food processing and conditioning fields such as cutting, grinding, mixing, blending, shaping, shaping, cooking and extreme extraction, improving food properties or preservation (such as oil extraction, starch separation, bean paste manufacturing, emulsification, coagulation or fermentation, sterilization , freezing or drying, etc.); the preparation room for inner packaging materials (referring to the inner packaging materials that can be used directly without any cleaning and disinfection procedures, and the operation place for removing outer packaging or forming, etc.); inner packaging Material preparation room (referring to the inner packaging material that can be directly used without any cleaning and disinfection procedures, and the operation place for removing outer packaging or forming, etc.); buffer room refers to the raw materials or semi-finished products directly entering the controlled production area without going through the normal manufacturing process In order to avoid direct communication between the controlled production area and the outside world, a buffer place is set at the entrance. 6. Cleanliness standard for decoration of class 100,000 dust-free pharmaceutical cleanroom 1. Large allowable number of dust particles (per cubic meter). 2. The number of particles greater than or equal to 0.5 microns shall not exceed 3,500,000, and the number of particles greater than or equal to 5 microns shall not exceed 20,000. Recommended pharma machinery: dust particle counter 3. Maximum allowable number of microorganisms. 4. The number of planktonic bacteria shall not exceed 500 per cubic meter. Recommended equipment: planktonic bacteria sampler 5. The number of sedimented bacteria should not exceed 10 per petri dish. 6. Pressure difference: The pressure difference between clean rooms of the same cleanliness level should be consistent. The pressure difference between adjacent clean rooms of different cleanliness levels should be ≥5Pa, and the difference between clean rooms and non-clean rooms should be ≥10Pa. Recommended instrument: differential pressure gauge 7. Temperature and humidity requirements: When the 100,000-level clean room has no special requirements for temperature and humidity, it is advisable to wear clean work clothes without feeling comfortable. The temperature is generally controlled at 20~22℃ in winter; 24~24℃ in summer 26°C; fluctuation ±2°C. The humidity of the clean room in winter is controlled at 30-50%, and the humidity in the clean room in summer is controlled at 50-70%. Recommended instrument: temperature and humidity meter 8. Power distribution: the general illuminance value of the main production room of the clean room (area) should be ≥300Lx; the illuminance value of auxiliary studio, personnel purification and material purification room, air lock room, corridor, etc. should be 200~300Lx. Recommended instrument: illuminometer 7. Structural system of food clean room: According to the 'Design Specification for pharmaceutical cleanroom', the walls and ceiling of the pharmaceutical cleanroom must be constructed with materials that do not produce dust and that do not accumulate dust and have a smooth surface, and there should be no si angles in the workshop. . The special color plate for construction is used, the top plate of the base plate is made of Baosteel's 0.4 steel plate, the core material density is 14kg/m3, and the aluminum material is made of Hualian special aluminum profile. Perform electrophoresis. The above is a summary of how to do the purification project and the precautions for the decoration of the food clean room.
