Factors to consider for drying
Thread Content
1. Properties of the material. 2. Properties related to the moisture content of the material. 3. Requirements regarding drying output and the desired level of dryness. 4. Subsequent dust removal requirements. 5. Requirements for the working environment. 6. The sequence of processes in the material drying process. (State methods related to feeding and discharging materials) 7. Energy consumption requirements 8. Operating requirements 9. Installation requirements 10. Site constraints. 11. Capital invested 12. Easy for maintenance. 13. Local average annual temperature and humidity. 14. Compare the different drying methods to determine the most appropriate one
Here’s one more thing: the choice of heat source as well
I’d like to add one more point: the specific surface area of the material during the drying process cannot be ignored, as it affects the heat transfer efficiency.
