Design of Clean Drying Room in Pharmaceutical Aseptic Workshop Design of Clean Drying Room in Pharmaceutical Aseptic Workshop In the medical aseptic workshop, a large number of vessels used in the production cycle need to be washed and dried. The clean level of the clean area as the auxiliary production area generally requires D level, and the drying room is no exception. After cleaning in a clean environment, the dehumidification and drying of utensils that contain a lot of moisture has become a problem we have to solve. We use examples to show that reasonable design can achieve energy-saving, drying and dehumidifying effects, which has certain theoretical guidance and practical application significance for this work. 0 Preface Dehumidification is mainly divided into three types: heating and dehumidification, cooling and dehumidification, and desiccant adsorption dehumidification. In the past, the most commonly used method was heating, heating, ventilation, and dehumidification. However, in a clean environment, simply adopting the method of full delivery and full row heating and dehumidification, the energy consumption is large, and the load on the clean filtration system is also large, so we designed cooling and dehumidification 1. Comprehensive dehumidification method of heating and dehumidifying clean air circulation. 1 Principle In the actual design, a small amount of fresh air is added to maintain the pressure

Clean room standard clean room dust-free workshop grade division 2022-12-15
The clean room (clean room) is divided into many levels depending on the degree of cleanliness. At present, the clean room grades of various semiconductor processing and panel assembly factories are mostly 1000 and 100. The smaller the number, the higher the cleanliness level. The concept of the clean room (clean room) 1000 class is: no more than 1000 dust particles per cubic foot or more; The concept of Class 100 of clean room (clean room) is: no more than 100 dust particles per cubic foot or more; Note: the particle size controlled by each level is also different; According to the standard issued by the US federal government [Federal Atandard (FS) 209E, 1992], the clean room (clean room) can be divided into six levels. They are Level 1, 10, 100, 1000, 10000, and 100000; If the level of the clean room (clean room) is described by only the number of dust particles, it can be assumed that the size of the dust particles is not 0.5 um, and the clean room level should be expressed in a series of specific dust particle sizes. For example: level 10 is 0.2um (dust size is 0.2um or more, density is not more than 75/cubic feet), level 1 is 0.1um (dust size is 0.1um or more, density is not more than 35) Pieces per cubic foot). The clean room required for integrated circuit manufacturing must have a cleanliness level better than 1000. First, the federal specifications clean room level Today, the federal specifications set by the United States are generally pursued, and the BCR refers to the NASA specification for the biological particle limit. The Fed.std cleanliness is expressed by how many microparticles of 0.5 μm or more are contained in 1 ft 3 of air, and is called [grade ○ ○]. For example, when there are 10 or less in the air, it is expressed as "level 10". Second, the natural atmosphere usually contains 300,000 to 30,000,000 particles. Under the JIS standard

How to make the clean room more energy-efficient? 2022-11-07
1. Low Section Wind Speed Design Cross section wind speed is the speed at which air passes through the filter or heating/cooling coils in air handling components. Most engineers design air handlers to 500 inches per minute based on "experience." Although this design saves time, it increases operating costs. In low profile wind speed designs, larger air handlers and smaller fans are used to reduce the air flow rate and reduce energy consumption and life-cycle costs. The pressure drop determines the energy loss of the fan. From the [square rule", it can be known that the pressure drop is proportional to the square of the speed drop. If the section wind speed decreases by 20%, the pressure drop will drop by 36%; if the section wind speed decreases by 50%, the pressure drop will drop by 3/4. According to the [cubic rule", the change in fan energy consumption is proportional to the cube of flow change. If air flow is reduced by 50%, fan energy consumption will drop by 88%. As a result, larger size air handlers, larger filters, and coil areas consume less fan power, allowing smaller fans and motors to be used. Small fans add less heat to the air, reducing the difficulty of cooling. Smaller coils are easier to clean and work more efficiently, so the temperature of chilled water can be higher. Filters work better and last longer at low cross-section wind speeds. The design reduces the pressure drop of air and water
Cleanroom Cleanroom Cost Analysis 2022-10-21
To solve this problem, we first propose a concept: Each clean room is unique, so there will not be a fixed package for reference. However, we can list the factors that affect the cost, as a reference for the cost. 1. Level level, the market can be divided into conventional: 10, 100, 1000, 10,000, 100,000, 300,000, a million ... ... the smaller the smaller the number of stages, the higher the degree of cleanliness, The higher the cost 2. The production process is continuous, and each room has no independence. It is suitable for large-scale production processes. The dust-free workshop has a large area, a large number of rooms, and a relatively centralized location. However, the cleanliness of each room should not be too different from each other. The forms and different layouts can realize multiple air distribution methods, unified delivery and return air, centralized management, and complex system management. The clean rooms cannot be individually adjusted and the maintenance volume is small. The cost of this clean room is relatively low. 3. Single production process, independent of each room, suitable for renovation projects, dust-free workshops are scattered, single dust-free workshop can realize a variety of airflow organization, but noise and vibration need to be controlled, operation is simple, maintenance is small, adjustment Easy to manage, the cost of this clean room is high. 4. In the desig
Clean shower room maintenance 2022-10-19
First, clean Use a soft, dry cloth to clean the four sides and the bottom of the shower room. If there is slight dirt, please clean it with a soft cloth or sponge with a mild detergent.

IC clean room design and construction requirements 2022-10-06
The integrated circuit clean room is a clean room that meets the needs of the semiconductor manufacturing process. The clean room has certain requirements for environmental cleanliness, temperature and humidity, vibration, ESD, and AMC control. Compared to other industrial cleanrooms, integrated circuit manufacturing dust-free workshops have features such as large area, high cleanliness level, and high temperature and humidity control accuracy. According to the characteristics of the clean room workshop air circulation, the clean room can be divided into three types: a circulating air conditioner with an efficient air supply system, a circulating fan with a wet sealing system, and a FFU circulation system. The first form is widely used in the design of small-scale and low-level clean room workshops. For large-scale and high-grade clean workshops, there are disadvantages such as high operating costs and excessive space occupation. The second form of design can meet the high-level requirements of large-area cleanrooms for integrated circuit manufacturing, but the operating costs are high, and the clean room wind speed, air volume adjustment is difficult, the system upgrade is difficult, so the operating flexibility is very low.
