Cosmetics, food, health products industry clean workshop decoration purification engineering design planning_Purification knowledge_News_sz-pharm1
Clean workshop refers to the removal of particulates, harmful air, bacteria and other pollutants in the air within a certain space, and control of indoor temperature, cleanliness, indoor pressure, airflow velocity and airflow distribution, noise and vibration, lighting, and static electricity. A specially designed room within a certain range of needs. So what are the design planning, key points and grades of clean workshop decoration? Let sz-pharma take the clean workshop decoration of cosmetics, food and health care products industry as an example to talk about it. 1. Design and planning of clean workshops 1. Main points of moving line planning: review and analyze the paths of people and vehicles, pipeline systems, exhaust pipes, material handling and operation procedures, shorten the moving lines as much as possible, avoid cross-contamination, and prevent cross-contamination. Operators, chemicals, materials and other moving lines shall not be concentrated; a buffer zone shall be set up around the clean workshop; the entry and exit of manufacturing equipment shall not have a significant impact on the operation. Picture 2. Selection and arrangement of air filters with different air cleanliness in the clean workshop: for 300,000-level air purification treatment, sub-high-efficiency filters can be used instead of high-efficiency filters; air purification treatment with air cleanliness of 100, 10000, and 100000 Use primary-efficiency, medium-efficiency, and high-efficiency filters; medium-efficiency or high-efficiency air filters should be selected according to the rated air volume less than or equal to; medium-efficiency air filters should be centrally located in the positive pressure section of the purification air conditioner; Sub-high efficiency air filter. 3. If the air of some air purification systems cannot avoid cross-contamination after treatment, it cannot be recycled: crushing, weighing, batching, mixing, material preparation, tableting, coating, filling and other processes of solid materials; organic solvents Refining and drying process of refined APIs; radiopharmaceutical production area; pathogen operation area; production process that produces a large amount of harmful substances and volatile gases during production; purified air used in solid oral preparation granules, finished products, and drying pharma machinery. 2. Key points for attention 1. The production process flow is connected from top to bottom, and the flow of people and logistics are separated to avoid crossover. The flow routes of raw materials, packaging materials, products and people should be clearly defined. 2. The total area of the manufacturing, filling and packaging rooms for each production pharmaceutical cleanroom operation line shall not be less than 100 square meters; the total area of the filling and packaging rooms for simple sub-packaging production workshops shall not be less than 80 square meters. 3. The semi-finished product storage room, filling room and cleaning container storage room for the production of eye skin care cosmetics and baby skin care cosmetics shall meet the requirements of 300,000 class cleanliness; semi-finished product storage room, filling room and cleaning container storage room for other skin care cosmetics It should meet the cleaning requirements of 300,000 grades. Three, clean workshop grade standard Clean workshop is divided according to the air cleanliness grade. If the class of a clean room is only described by the number of dust particles, it can be assumed that the size of the dust particles is 0.5 μm. For example, the maximum number of dust particles in class 1, 10 and 100 clean rooms is less than or equal to 1, 10 and 100, respectively. If the dust particle size is not 0.5 μm. The clean room grade is expressed by the grade of specific dust particle size, which is divided into grade 1, grade 10, grade 100, grade 1000, grade 10000 and grade 100000. The smaller the value, the higher the purification level. The higher the cleanliness, the higher the cost. Requirements for cleanliness levels in various industries: Class 1 clean workshop: It is mainly used in the manufacture of integrated circuits in the microelectronics industry, and the accuracy requirements for integrated circuits are sub-micron. Class 10: Mainly used in the semiconductor industry with bandwidths less than 2 microns. Class 100 clean workshop: It can be used for aseptic production process in the pharmaceutical industry. Class 1000 clean workshop: mainly used for producing high-quality optical products, as well as testing, assembling aircraft snails, assembling high-quality miniature bearings, etc. Class 10,000 clean workshop: mainly used for the assembly of hydraulic equipment or pneumatic equipment. In some cases, it is also used in the food and beverage industry. In addition, 10,000-level clean workshops are also commonly used in the medical industry. Class 100,000 : Class 100,000 cleanrooms are used in many industrial sectors such as optical product manufacturing, small component manufacturing, large electronic systems, hydraulic or pneumatic systems manufacturing, food and beverage production, medical and pharmaceutical industries.
