1. The importance of temperature control

1. Affecting drying efficiency: Too high a temperature may lead to coking of the material or loss of heat-sensitive components; too low a temperature will prolong the drying time and increase energy consumption.

2. Determining product quality: Temperature fluctuations may cause uneven moisture content, agglomeration, or abnormal particle morphology in materials.

3. Equipment safety: Overheating may damage equipment components (such as bag filters, hot air ducts, etc.).

II. Key parameters for temperature control

1. Inlet air temperature: It directly affects the drying rate and is usually set according to the characteristics of the material (e.g., heat-sensitive materials require low-temperature drying).

2. Outlet temperature (exhaust gas temperature): Reflects the end point of the drying process and needs to be controlled within a reasonable range to avoid moisture regain or excessive drying.

3. Material temperature: Monitor the real-time temperature of the material during the drying process through sensors to prevent overheating.
