[0002] Fluidized bed dryer is a kind of equipment commonly used for drying solid materials. According to the properties of the material and experience, the drying effect and moisture content of the material can be controlled by adjusting the feed rate, discharge rate, air flow temperature and other parameters of the dryer.

[0003] During the fluidized bed drying process, the moisture content of the material will be affected by many factors, including the properties of the material itself, environmental conditions, and process parameters. The moisture content of the material will affect the effect and efficiency of the drying process. When the material contains a higher moisture content, it will take a longer drying time to reach the required moisture content. At the same time, the moisture content of the material will also affect the processing capacity of the fluidized bed dryer. Excessive moisture content may cause equipment operation problems. The common detection method is to regularly extract material samples from the dryer and send them to the laboratory for moisture content determination.
