The sum of the heights of the stirring paddle units is greater than 1 / 2 of the height of the kettle body, which makes the stirring more uniform. The top end surface of the curved stirring paddle and the bottom end surface of the side wall of the kettle body are located on the same plane, that is, the inner wall of the bottom end of the kettle body is in contact with the curved stirring paddle, so that there is no dead angle in the inner wall of the bottom end of the kettle body, and the stirring is more uniform.
