AI Technical Summary
During the drying process of polyacrylamide powder, existing equipment is difficult to achieve uniform heating, which leads to local overheating and degradation or side reactions, and the material is not dried evenly.
The system employs heat-conducting plates placed close together inside the drying chamber to form a material channel, and air channels are set in the heat-conducting plates to allow hot air to pass through evenly. Combined with the design of vertical pipes and conical hoods, it ensures that the hot airflow flows from bottom to top to avoid blockage. Temperature sensors are used to monitor and control the heating temperature.
This method achieves uniform heating and efficient drying of polyacrylamide powder, avoiding localized overheating and clogging, and improving drying efficiency and product quality.
