Inaccurate ratio can directly affect the quality and performance of the product, so that the final product may not meet the expected standard. In addition, the auxiliary materials frozen on the pipe wall need to be manually removed, which not only increases the production cost because more manpower and time need to be invested, but also may cause the production line to stop and delay. The process of manual removal is time-consuming and laborious, and the residual material on the pipe wall may not be completely removed. These residues may continue to affect the quality of the product in the subsequent production process. SUMMARY
