　　Freeze dryer China daily maintenance is quite important work
　　Freeze dryer China is used in biopharmaceutical fields such as antibody, protein, tissue, microbiological research. The entire system is composed of a refrigeration system, a vacuum system, a heat transfer oil heating system, and a dehumidification system. A freeze-dryer is a technical method that mainly freezes water-containing articles in advance, and then sublimates the water in a vacuum state to obtain dry articles. The freeze-dried articles are easy to be stored for a long time. After adding water, they can return to the state before lyophilization and maintain the original biochemical characteristics. For heat-sensitive substances such as antibiotics, vaccines, blood products, enzyme hormones and other biological products, freeze-drying technology can show its superiority. Therefore, the daily maintenance of the freeze dryer is a very important task.
　　1. The freeze dryer should be installed in a room with an ambient temperature of 2 to 38 ° C, well ventilated, and clean air; in particular, avoid corrosive components (such as ammonia) in the air. When the indoor ventilation department is good, install exhaust equipment in the equipment room.
　　2. There should be a distance of at least 4 to 5 meters between the cold dryer and the air compressor to prevent the vibration of the air compressor from affecting the normal operation of the cold dryer.
　　3. The distance between the gold vent of the freeze dryer and the wall is more than 1.5 meters, and the inlet of the two dryers cannot face each other. There should be a certain space around the dryer to facilitate repair and routine maintenance.
　　4. If the quality of the cooling water of the freeze dryer is poor, a water filter should be installed at the cooling water inlet. The temperature of the cooling water is preferably 10 to 32 ° C, and the water pressure should be maintained between 0.15 to 0.35 bar.
　　5. When the dryer is running, its own vibration is extremely small. Only when the foundation is soft, the cement foundation needs to be made, and the foundation needs to be flat. The impact of air compressor vibration from the air pipeline should be avoided. If it is too serious, a high-pressure hose needs to be connected to eliminate the vibration.
　　6. The outlet of the automatic drainage outlet should be connected to the drainage ditch to avoid polluting the production environment. The height of the drainage ditch cannot be higher than the drainage outlet.
　　7. The cold and dry machine is connected to the air source system. It is best to make a bypass pipe between the air inlet and outlet. A bypass ball valve is set in the middle for debugging and maintenance.
