The maintenance of the refrigerated spray dryer includes the following aspects:
Daily maintenance: regularly check the working conditions of the drying chamber, pneumatic valves, control valves, temperature instruments, pressure instruments and other components of the refrigerated spray dryer to ensure the normal operation of the equipment. At the same time, it is necessary to regularly clean the dirt and impurities on the surface of the temperature instrument and pressure instrument, and check whether the value displayed on the instrument meets the specified requirements.
Weekly maintenance: The drying chamber of the spray dryer needs to be cleaned every week to remove rust, scale and impurities. At the same time, it is necessary to check the air breaker valve and remove foreign matter from the filter screen of the air breaker valve. Lubricate the cylinder and pneumatic box door to ensure that the drying chamber of the spray dryer can have a relatively high degree of sealing. In addition, it is necessary to check the working condition of each component and stop the machine immediately if there is any abnormality to prevent the failure from expanding.
Monthly maintenance: It is necessary to check the electrical contacts, low-voltage protection switches, gas circuit system, water system and other aspects of the freeze dryer every month to ensure the safety of the equipment. At the same time, the air filter should be cleaned regularly to avoid excessive pressure drop in the air pipeline due to impurity blockage.
Annual maintenance: A comprehensive inspection and maintenance of the refrigerated spray dryer is required every year, including changing the lubricating oil, cleaning the condenser, etc. At the same time, the equipment should be comprehensively inspected and tested to ensure the performance and safety of the equipment.
In short, the maintenance of refrigerated spray dryers needs to be carried out regularly, including daily maintenance, weekly maintenance, monthly maintenance and annual maintenance. Only by doing a good job in the maintenance of the equipment can the performance and life of the equipment be guaranteed.
