Injection production dust-free purification workshop
In the production of injection purification pharmaceutical cleanroom, the filtration process usually does not use one type of filter equipment, but two or more types of filter equipment are often used in series to ensure the quality of injection; The relative position and distance of the area, the combined filtration equipment can be divided into three types: high-level static pressure filtration, decompression filtration and pressure filtration; high-level static pressure filtration device mainly uses the pressure generated by the liquid level difference to filter, the speed is slow, It is suitable for small-scale production or upstairs liquid distribution through pipelines to downstairs for filtration, filling and sealing; the decompression filter device uses a vacuum pump to evacuate the entire filter system to form a negative pressure and pump the filtrate through the filter medium. The reasonable design can achieve continuous filtration , the whole system is also in a good airtight state; but the pressure of decompression filtration is sometimes unstable, which is easy to loosen the filter layer and affect the filtration effect. At the same time, because the whole system is in a negative pressure state, some microorganisms or impurities are never sucked into the system and pollute the product. Therefore, the decompression filter should not be used in the sterilization process.
Pressurized filtration mainly uses centrifugal pump to pressurize the filtration system to achieve the purpose of filtration. Due to the large and stable pressure, the filtration speed is fast, and the entire system is in a positive pressure state, with good airtightness, and it is difficult for debris and microorganisms in the air Contaminate the filtrate, and the liquid can be continuously filtered repeatedly, and the filtration quality is good, but the air entering the system must be filtered. Ampoules are containers for sterile liquid medicines. Microorganisms and insoluble dust particles are not allowed in ampoules. However, it is difficult to avoid environmental pollution during the manufacturing and transportation process of ampoules, so that ampoules cannot meet the requirements of injection filling without washing and disinfection. Hygienic requirements, so in the production process of injections, ampoules must first be repeatedly cleaned, and then sterilized and dried before they can be used for filling; commonly used ampoule washing equipment includes spray-type ampoule bottle washing unit, air-water jet washing machine There are three types of bottle unit and ultrasonic ampoule washing machine. Zhongjing Global Purification can provide consulting, planning, design, construction, installation, transformation and other supporting services for injection purification workshops and sterile workshops.
Air-water jet ampoule washing machine is suitable for washing large size ampoules and revolving neck ampoules. The machine is mainly composed of water supply system, compressed air and its filtration system, and bottle washing machine. The filtered compressed air of the washing machine sprays the inside and outside of the ampoule alternately through the nozzle to clean the ampoule. Ultrasonic ampoule washing machine is a device that uses ultrasonic technology to clean ampoules. It is a relatively advanced ampoule cleaning equipment that can realize continuous production. A kind of 'cavitation' effect generated when the contact interface is in the state of severe ultrasonic vibration, the dirt on the inner and outer surfaces of the ampoule is impacted and removed, so as to achieve the purpose of cleaning the ampoule; when the ampoule is immersed in the ultrasonic cleaning tank, it not only guarantees The cleaning of the outer wall of the ampoule can also ensure that the interior of the ampoule is dust-free and sterile, so as to meet the cleanliness requirements.
Although the washed ampoules have washed away large bacteria, dust and foreign particles, some live microbial particles need to be removed by drying and sterilization, so as to achieve the purpose of sterilization and depyrogenation, and can also be removed at the same time. Moisture in the ampoules; under normal circumstances, the washed ampoules are placed at 350-450 ° C and kept at a temperature of 6-10 minutes, which can achieve the purpose of sterilizing bacteria and pyrogens, and can also dry the ampoules; drying and sterilization equipment There are many types, which are divided into intermittent type and continuous type according to the continuity of production. The energy used is steam, gas and electric heat.
