Material purification in dust-free pharmaceutical cleanroom
The objects in the dust-free pharmaceutical cleanroom must be purified before they are sent to the clean area. The indoor equipment and material entrances and exits should be set up according to the nature and shape of the equipment and materials. The material purification room and its facilities, the layout of the material purification room , It should prevent the purified materials from being polluted during the transfer process; some objects only need to be purified once, some need secondary purification, the primary purification does not require the purification of the indoor environment, and can be located in a non-clean area, and the secondary purification requires indoor environment It also has a certain degree of cleanliness, so it should be located in the clean area or adjacent to the clean area; materials should generally enter the clean area through the air lock room, and the air lock room is often adjacent to the clean area or in the clean area, so its A reasonable pressure difference should be maintained between the indoor air pressure and the clean production area, so that the purified air flows from the clean production area to the preparation room.
If the production flow in the workshop is strong or in order to prevent mutual contamination or cross-contamination of clean areas of different levels or the production process requires to prevent unnecessary cross-contamination, materials should pass through the transfer window or other The devices are transferred in sequence; in order to adapt to the different situations of material transfer between products and intermediate products between processes, different types of transfer windows are used. Mechanical interlock switch, that is, when one door is closed, the other door can be opened; in the case of frequent closing or opening for a long time, some air curtains with high-efficiency filters are also installed in the box. Zhongjing Global Purification can provide consulting, planning, design, construction, installation, transformation and other supporting services for clean rooms and clean rooms.
Pass-through sterilization equipment is often used in sterile clean areas to transfer materials. After inputting materials, they will be heated and sterilized for a period of time, and then open the other end door of the sterile room to take out materials; Holes are opened on the partition wall of the car to continuously output the finished products through the wall, so the hole becomes a weak link in indoor purification. The general solution is to increase the indoor positive pressure, or set up an air curtain device above the hole at the same time; when transporting small items In the case of ensuring the positive pressure in the room, the conveyor belts can also be set on both sides of the hole, and the hole is equipped with an ultraviolet lamp. In the zoning design of the material purification, it needs to be organically combined with the process flow, the layout of the purification air-conditioning system and the transfer of materials, etc. At the same time, the material purification route should be concise and clear, avoiding round trips, excessive twists and turns and crossings, and the space should be opened as much as possible. Open and smooth, and should be considered together with safe entrances and visiting routes.
