Through the setting of the fixing rod 13, it is ensured that the feeding tube 9 will not fall off due to shaking during the rotation of the spiral stirring blade 11, thereby ensuring the successful operation of the device.
[0023] The feeding tube 9 is provided with an installation groove 15 inside, and the heating pipe 12 is installed inside the installation groove 15. One end of the heating pipe 12 is electrically connected to the heating module 8 located on the outer wall of the shell 1 through a fixing rod 13.
