During operation, it drives the round rod 343 and stirring blades 344 to rotate slowly. The drive motor 342 is a variable frequency motor, which can adjust the speed of the spiral shaft.

[0059] In some embodiments, in order to install or remove the cover plate body 341 by gripping and rotating the cover plate body 341 through the ear plates 4 on both sides of the side wall, ear plates 4 are fixedly mounted on both sides of the cover plate body 341.
