In recent years, a large number of health products have been used in freeze dryers, and various freeze-dried health products have been active in the health product market. At present, the freeze-drying industry has made great progress, and its application fields have gradually expanded. Freeze-drying technology is actually a method of removing water and using a specific method to preserve the material.
　　1. The freeze dryer should be installed in a room with an ambient temperature of 2 ~ 38 ℃, well-ventilated surroundings, and clean air; especially avoid corrosive components (such as ammonia) in the air. When the indoor ventilation section is good, the exhaust equipment must be installed in the machine room.
　　2. The distance between the cold dryer and the air compressor is at least 4 to 5 meters to prevent the vibration of the air compressor from affecting the normal operation of the cold dryer.
　　3. The distance between the air inlet of the cold dryer and the wall is more than 1.5 meters, and the air inlet of the two dryers must not face each other. There should be a certain space around the cold dryer to facilitate repairs and daily maintenance.
　　4. If the cooling water quality of the dryer is poor, a water filter should be installed at the inlet of the cooling water. The temperature of the cooling water is preferably between 10 and 32 ° C, and the water pressure should be maintained between 0.15 and 0.35 bar.
　　5. When the dryer is in operation, its own vibration is extremely small, and it is only necessary to make a cement foundation when the foundation is soft, and the foundation needs to choose a flat place. The impact of air compressor vibration from the air line should be avoided. If it is too severe, a high-pressure hose needs to be connected to eliminate the vibration.
　　6. The outlet of the automatic drain should be connected to the drain to avoid polluting the production environment. The height of the drain should not be higher than the drain.
　　7. When the cold dryer is connected to the air source system, it is best to make a bypass pipe between the air inlet and the outlet, with a bypass ball valve in the middle for debugging and maintenance.
