[0034] During the stirring process, the plastic is in full contact with the heating tube 13 and the multiple heat conducting plates 14 connected to the side walls of the heating tube 13. The heating tube 13 can heat the plastic near the side walls of the stirring box 10 to maintain a suitable stirring temperature. The multiple heat conducting plates 14 can fully heat the plastic near the stirring rod 12 in the center of the stirring chamber 11.
